Quite a few 2008 Viper Owners have purchased or are considering a purchase of Belanger headers for their new Vipers. Great! However there is a special note that we have been asked to pass along: These headers have NOT been tested and/or tuned by Chrysler or SRT to be OBD II compliant. As such, there is a very real possibility of Malfunction Indicator Lamp (MIL) illumination (check engine light) and resulting driveability issues that are NOT covered by the factory warranty.
Bottom line? The factory control module has not been calibrated for aftermarket headers, so any resulting check engine light issues are the owner's responsibility - not Chrysler's. |

And on a personal note, we have Belanger headers on our 2005 Viper and absolutely love them. We have never had a single issue with them and have put about 10,000 trouble-free miles on 'em with our DLM build. Lou makes great exhaust systems for the Viper, so be sure to work with your tuner for best results.

As someone who currently has the Belanger system installed, was it Chrysler who asked to pass this message along? Thanks. /Rich

Rich -
I am not going to comment on the source other than to say they have a vested interest in this. We had been asked to keep it confidential. Thanks for your understanding, Chris PS. I assume you aren't having any issues with check engine lights? |

Relevant posts from the recent SRT Engineer chat. See below. These, taken together with the above news mean to me that the bottom line is that you spend your money and take your chances. If something goes wrong, it has been made clear that Dodge's warranty will not cover it. Is there a warranty with the headers? And, if so, what does it cover?

Can you please tell us, once and for all, whether there will be a Mopar horsepower upgrade for the 2008 model or not. There has been much speculation that such an upgrade to the 675 hp. range is forthcoming sometime in the future. Recently, however, one source advised that this is not going to happen. We continue to look at opportunities but at this time there are no definitive plans to release a kit. I am seriously considering adding the Belanger exhaust system to my ACR when it arrives, however, wanted to know if something was coming from Mopar that I should wait for. Thank you. Understand that you're looking for something to get a bit more performance however while we have some experience with the Belanger system we can't endorese it. Quote: Originally Posted by Bobpantax 5.

If so do you have any specs on the preferred pistons to use? Bob, The 2008 engine is a highly tuned and highly stressed engine. We left few stones unturned in the development or calibration process. Achieving 600 HP required that many of the parts be stressed to their limits and the pistons are one of the most highly stressed components in the engine. If the customer modifies the engine to increase the output by any significant amount (more than just say headers, i.e. supercharger, turbo, NOS), a quality forged piston would be a good idea. We don’t currently offer a replacement piston but many of the aftermarket suppliers could probably offer a good replacement part. Follow their recommendations for fit. Also be careful to make any adjustments for balance if the weight is much different than the stock piston. Don't forget to use a good engine builder and make sure the calibration matches the modifications!

All of this is another reason why I believe 3.33 rear gears should be any '08 Viper owner's first performance mod. No ECU issues, faster in the 1/4mi. and more fun to drive in 1st and 6th gears, and easier on the life of the clutch too!!

I had a very lengthy conversation with Lou Belanger about the '08 headers/exhaust even though I didn't call him about that specific product. The man went into incredible detail about the '08 exhaust, testing and the science that went into it. I wish I had recorded that conversation so I could post it here. If anyone has any doubts about the '08 Belanger headers/exhaust I highly recommend that you call the man yourself and ask him about it. Please post the info you receive here.

Look at the last quote from the engineers. The Gen 1 and Gen II engines, at least through 1999, were tough as nails. With the elimination of forged pistons in 2000, the engine got a little weaker. With the use of the SRT8's cast pistons in the '08, the engine, as the engineers said, the engine is more stressed. The way I read what they are saying is that there is no envelope or little envelope to stretch with the '08 engine. Minimal remedy - change out the pistons. However, this will not solve any programming issue that might arise. And that appears to be what the recent news is about.

So it is mostly a programming issue... The engineers also said this implying the hp increase seen by adding headers should be ok for the pistons
If the customer modifies the engine to increase the output by any significant amount (more than just say headers, i.e. supercharger, turbo, NOS), a quality forged piston would be a good idea. |

Also the srt8 gc guys have been modding their engines with nitrous , headers , tune, and have no issues achieving even 3 second 0-60 times... i think there are even supercharged srt8gc out there..

The stock SRT8 environment is either 420 HP or 425 HP depending on the SRT8 model. Thus, it is one thing to mod a 420/425 HP engine with the SRT8 pistons. It is an entirely different matter to mod the stock 600 HP engine with the same SRT8 pistons. As the engineers carefully stated, the '08 engine is HIGHLY STRESSED. Short of hitting us over the head, they could not have been more clear.

Okay, dumb question for the day. If the Belanger headers/exhaust is potenially detrimental for the engine, why did Ralph Gilles put them on his ACR?
|
|

|

#15 |

I don't think Mr. Giles needs to be concerned about warranty issues. He also has daily access to SRT engineering input if he desires same. The engineers used the word "may" for a reason. They also used the phrase "highly stressed" for a reason. I am sure that they caused the recent programming alert to be issued for a reason. The bottom line is that unless a warranty is issued with the headers that covers any problem, any problem that arises attributable to the headers, if any, is not covered by the OEM warranty. And that has been made crystal clear. Until Chrysler issues a public statement to the contrary, this is the reality we have to deal with.

Fact of the matter remains that Lou's headers "fit" within the "tight" tolerances of the factory PCM without throwing a code of any kind. This speaks volumes of the research that went into his design of the system. "IF" there was going to be a problem with the longevity of the engine the controller WOULD NOT allow it and throw a CEL right?
Some circles cannot by any means endorse the removal of ANY emissions device for a non off road application and that is exactly why I think they choose the wording the way they do, end of story. IMHO of course. Thanks all Belangers FTW!!!! off road of course.

If the VCA was spending on Chrysler's legal budget, the VCA's highly paid lawyer might have said" "DON'T MENTION ANY BRAND NAMES."
----------------------------------------------------------------------------- Lou Belanger was a bit blindsided by this post, and Lou has a call in to our esteemed treasurer. He relates that Dodge has bought over 140 sets of Belanger headers for everything from Comp Coupes to developmental Vipers. NO header has ever been returned / rejected by Dodge to Belanger. Dodge also bought and tested other brands. But what is on the Comp Coupe? Mclaren performed EXTENSIVE testing for "someone" and Belanger did NOT pay for it. Who did? Arrow also did extensive testing of these headers. For who? Belanger did not pay for it. McLaren also tested other brands, Belanger was told. But it was 2008 Belanger headers that were a PART OF DODGE'S DISPLAY at the 2007 NAIS Auto Show as seen here. When Dodge raced the F-16, the public line was "All Stock, (WINK!)" I saw what was under the hood on that 2008 Coupe. {Belanger even attended and donated a set to Dodge's charity event there.} It is a touch misleading to come here out of the blue and say "Hey All, not OBD-II Compliant." Weasel Words. Lou sells all these components labelled for OFF ROAD USE, the same as Mopar sells stuff. So this question remains: ON Board Diagnostic -II systems monitor emmisions compliance. Since the Belangers seem NOT to throw any post-break-in CELs, in the vast-vast majority of 2008s, (and none of the 1996.5-2006) then WHERE IS THE NON COMPLIANCE? You dont need (illegal) simulators to trick OBD-2 ! The Belangers just WORK! Tacit Compliance. Does it mean they will likely pass emissions testing where required? Yup. Does this make them "Federally tested " and / or certified ? Nope. Hell, half the MoPar parts are sold "off road use" only, and "no warantee of any kind." What is the difference here? This post is also potentially damaging to Belanger's business, and the VCA being the 'mouthpiece' of this anonymous post is just, well..... ____. (I just cannot seem to find the right word.) Strange? We just LOVE our anonymity here. Don't dare shout "FIRE" but it's OK to shout "SMOKE" ? I guess we have the basis for an entire new SRT Chat ...

Those same lawyers probably advised Chrysler to say NOTHING....so that is probably why it seems so ________ (weird / strange / obvious / appropriate? / inappropriate ?) that the VCA is the mouthpiece. It is also historic. The warranty process from 4/94 til 2007 was written one way, but performed with a different, relaxed philosophy. Taken along with HUGE parts price increases, Methinks this historic and ___________ post may be a bow-shot of sorts. Quote:

Mark and Jon. Thank you for your posts. I think that the utterances of the SRT engineers, including the most recent one, are meant to manage the expectations of those who mod their cars. With the intense concern over dollars at Chrysler LLC, I am not surprised at their action. I think the simple marketing solution is for Lou, if he has not already done so, to provide a limited warranty that covers any damage to the engine if it can be shown that same was directly caused by the use of the headers. If, as you and others say, they work flawlesly, the cost of providing the warranty should be little to nothing. Paxton provides a limited warranty with its supercharger - why not a header manufacturer?

Chris,
It's been a few years since I've posted anything on the VCA classisfied section but when I went to list one of my Vipers for sale today (you used to handle all that stuff for me) I was not prompted for my VCA membership number and it appeared I was going to incur a fee if I completed the listing and submitted it. As a dues paying Venom member I thought free listing was one of the perks. Was I wrong? GLT

One more observation. If the message passed on by Chris was from Mopar as opposed to the SRT Engineers, it makes even more sense for Lou to issue a limited warranty. Mopar, assuming that they ever get their act together well enough to create a workable set of headers for the '08, will never issue such a warranty. So, if Lou does, it will allow him to obtain a greater market share. JM2C's.

limited drivetrain warranty seems like a decent idea....installation would probably have to be done by a certified installer though

Besides why would headers cause more stress on the engine?....i'm no mechanic(obviously)but all the headers are doing are allowing combusted gases to exit the chamber more efficiently thereby allowing the piston head to rise up easier and therefor putting less tension on the piston and less passive resistance on the driveshaft...right? The piston goes thru 2 phases.. the first phase is when the piston goes down and the gas/air mixture is introduced , then the piston goes up , compresses the gases and they are ignited...this is the phase that causes stress on the piston and the headers have no effect on this phase whatsoever... is my logic right?
Seems to me the headers are causing the pistons to work less o well i've said enough... i'm putting my faith in belanger/jorgensen/partsrack |

Thanks Wall....but the SRT Engineers know this Answer (but apparently not from any testing!) Performance Headers create extra TORQUE on the crank and rods etc.

I completely respect your need to protect sources. My questions was only trying to clarify whether this message was prompted by a specific problem encountered by the source of the message or whether the message was just a generic disclaimer regarding the use of aftermarket parts on the 2008. I fully understand from the documentation that came with my Belanger system that it is designed as "Off Road Use Only" and has not been federally certified. My concern lies with whether the source of the message has encountered specific programming or driveability issues that I as a consumer should be made aware of. Thanks for any help you can provide clarifying this. /Rich

Okay, in all seriousness and without any of the personal BS that seems to infect many a post, here is the deal as I see it:
As for me, if I can score one of these 2008's or 2009's (shhh, don't tell Venomiss), Belanger headers will be the FIRST modification I do - then the MGW shift kit. Fuzzy dice come later and I don't care if they throw a "check windshield" light or not. Over and out, Chris |

It appears that all of the consternation would have been avoided if VCA posting policy #9 had been followed in the initial post.
