How do the factory headers compare to after market headers?

They cant be that bad

[Chuck 98 RT/10]

They aren't.

[JWVIPER]

They aren't.

Chuck, you alway have good info, folks have led me to beleive the Gen I (mine) will gain more from header upgrade then Gen II, any thoughts ?

JW -- I'll be able to tell you EXACTLY how much in about two weeks. It'll be the only upgrade between dyno pulls. Will let you know. (96 RT/10)

He asked if the factory headers were that bad. I'm just saying they are not that bad.

You will get HP gain from headers and exhaust. Probably somewhere between 20 - 35. Headers only will be less. Having side exhaust prepare for some loudness.

CHuck, thanks Im sure you will gain no matter what car but was just trying to see if you knew if there was any truth to what some are telling me in that the Gen I exhausat manifold design is inferrior to the Gen II in that Gen II is a lot closer to that of an aftermarket header design thus a Gen I upgrade wwould see more benefit. Looking to upgrade my system along with rear shortly.

Depends on the year of GenII as well. The creampuff cars had a little better header than the earlier GenII's.

Here is a comparison of a stock '01 header setup to a Belanger aftermarket header.

Great shot, thanks, working with Belanger for prices and complete system choices now.

Janni Cone did some excellent analysis comparing the later Gen II headers to Gen I. Along with a possible slightly better flow she discovered the 98 and newer headers were 23lbs lighter if I recall correctly. Based on her conclusions I have a set of the newer headers that I will someday get around to installing on my 97 for just a bit more than shipping cost. I'm just not prepared to spend the high price on long tubes right now. Somebody revive me when they are more reasonably priced.

The highest increase I've heard of with long tubes and exhaust upgrade is 43hp. But I think most are around 30hp.

[JWVIPER]

Yeah, I agree that is what I was trying figure out, a lot Gen II stock one's around for very cheap, If I can pick up 15HP or so and put on the whole Roe Cat back to the sides, well not much diff other than maybe $800 vs $2500 for say 15HP. Can GEN II bolt on to my 95 ? Would love to put the $ toward new HRE's and rubber. Just an angle for me to look at, thanks....

You can install the later Gen II on an early Gen II or Gen I. Some modifications are required. For Gen I's the connections between the exhaust flanges need to be cut off as they interfere with the Gen I head bolts. You also either need to get the Gen II turnouts (90 turn with flexible link) or make a new one as the connection changes.

Well, I do have a set of B&B's basically brand new, I was going to use them, but the car I got had TNT's. I had them Jethotted(over $400) for the cooler engne compartment. If you want a REALLY good set of headers, PM me.

[RedEnuf93]

I have Gen 2 headers on my -93, 3" exhaust and smooth tubes.
410HP/477TQ

I had to cut the lower bars off, piece of cake.

I bought them from E-bay for 75 bucks.

Send them to me or I'll post the vid of your 39-second 100-yard sprint...Forrest.

It's not blackmail, I'm making an offer you can't refuse.
