What's the difference b/ween the Mopar Performance Exhaust & Race Exhaust

[FLYNLO]

There are 2 mopar exhausts available, One is the Performance exhaust that retails at 545 dollars, and the Race exhaust that retails at about 845 dollars. What exactly is the difference between the two, and which one is ultimately better?
here are the descriptions...

Street exhaust $545.99-

Features stainless steel construction with mandrel-bent tubing. This free-flow system provides a horsepower and torque gain, improved fuel economy, and a deeper tone. Includes 2 mufflers, right and left turn out assemblies, and four 2-1/2" clamps

Race Exhaust $849.99

This 3" Race Exhaust System provides low restriction from manifold to tip. Catalytic converters are eliminated (upstream and downstream), and it has a side exit from the sill that removes H-pipe crossover.


So which is better?

The race exhaust is 3". I think that's your difference.

[FLYNLO]

yea...it's three inches..but I think the race exhaust also eliminates the cats as well...I was reading about the race exhaust, and it said that it required the Mopar computer module to adjust for the loss of the cats..I was wondering if anyone has seen these systems first hand and could give me the better route to go..It's as easy as me calling my dealer tomorrow and ordering..I just want to make the correct decision.

And the race exhaust probably has more piping since it removes the cats!

[FLYNLO]

OK..i understand that much, which is why I question everyone who is putting on the Street exhaust. Why would you pay for something which will not net any HP increase since is doesn't remove the cats? Also, the street exhaust does not keep the cabin cool. So im guessing that the race exhaust is obviously the better one. However, I would like to hear from someone with first hand experience with the race exhaust...
thanks guys

[SRTRICKY]

You will gain HP with the street exhaust as well! It will also keep the cabin cooler. I dont' think the street exahust has a cross over and thats what causes the heat build up etc. I wouldn't run cat less on a viper! Get the street exhaust with high flow cats and you'll be happy! It will be loud though!!

[FLYNLO]

Hmm...I understand what you mean, however whenever i called my dealer, he told me that the street exhaust is on back order...So I have no idea when he would be able to get one for me. The race exhaust, I can get in 3-5 days. Why don't you think I should eliminate the cats in the vehicle? Would this trip a check engine light? Also, for the corsa track, how is it different in design to the mopar street exhaust? Doesn't the corsa eliminate the crossover?

www.partsrack.com Jon B can find the exhaust for you if anyone can.

Have you heard this setup? Today at the dealership I was quoted $545.00 for the Mopar Performance Exhaust. The guy said he hadn't heard it on a Viper but that he'd heard the Mopar on the Ram SRT-10. That it had a much deeper rumble than the stock system and that people would definitely hear you coming. He also said that the Mopar system and the Borla were one and the same.

I wish there were sound clips somewhere to be able to compare the Mopar and the Corsa (both with high flow cats). I would like the sound of my Viper to be a little more aggressive (and would especially like to get rid of the heat problem) - but not to the point that it's obnoxious or sets off car alarms or cause me to have to turn the volume way up on the radio just to listen to a song.

If you go to either corsa or borla on line you can listen to their exhaust. It might not be the exact sound that you looking but you get the idea.

Flynlo,

My opinion - get the street exhaust. I got mine from Roe Racing (took 4 days via std. Fed-Ex) and installed it this past weekend. To me the sound is perfect, loud enough but not annoying (although sound comes down to personal preference, you may think its too loud or too quiet, I have no idea). Easy installation, no problems at all as with another brand I have read numerous posts about not fitting correctly, falling off, burning paint, etc. It eliminates all crossover piping under the car, therefore there is less pressure drop through the exhaust system. Less pressure drop = more exhaust flow = more HP. I think I saw a claim of about +10 HP for this system on the internet somewhere but unless you dyno it before and after HP numbers are a guess. I can tell you that it now blows water out of the tips when first started and if you hold your hand next to a tip it feels like a hair dryer blowing on your hand whereas with the stock system this was not the case. Trust me, you will like it. Don't mess with eliminating cats, there are O2 sensors installed upstream and downstream of the primary cat, my guess is you will have diagnostic problems (check engine, etc..) if removing these cats, plus if you have to take a sniffer test it won't pass (I'm in Texas too...)

Thanks for the info slither. I was looking at the mopar parts catalogue, and i thought that the street exhaust did not eliminate the factory cross-over. This was my reasoning with going with wanting to purchase the race exhaust. I wish there was a way to put the race exhaust on because im sure it's louder than all of the systems. I like that obnoxious rumble When I called my parts guy at the local dodge dealership, he told me that the street exhaust was on a back order. I will ask again tomorrow...if you don't mind, what is the part number that you have for your mopar system?
thanks

PS. As for the sniffer test, I have my own service station, so inspections come rather easy, if you know what I mean

[GR8_ASP]

Now you guys have me thinking about another change. So does anyone own the track version (3") and can describe the sound?

[Tico]

Slither,

Does the Mopar street exhaust help in any way to eliminate some of the heat from the sidepipes? I ask because you said not to eliminate the cats and it was my understanding that cat elimination or high flow cats is what helps with the heat problem.

Thanks.

[Sellshomesdrivesviper]

Can someone tell me what exhaust will eliminate the side sill heat, and not screw up the paint, the size fits like the stock and remains sound wise relative to the stock as I think the sound is fine.
