What year car, BADVENOM? The later cars don't repond the same to exhaust modifications as the earlier cars did. In fact, Vipers w/o catalyst from 96 (GenII) to 99 have made 45+rwhp whereas the later car w/o catalyst would be lucky to see a 20+rwhp gain from the same components.

My car pulled 402rwhp stock, after the catback it pulled 412. After the headers it pulled 437rwhp and 498rwtq. I dont seem to remember the torque numbers for the first two pulls, I ll try to find the dyno sheets.

My Belanger headers, Random Tech high flow cats, and Belanger exhaust modifications only gained 17 rwhp... 97 GTS

Not quite the 50 rwhp gain that Belanger claimed I would get.

On a 98+ car I'm with Larry. GREAT sound, but bang for the buck.....NOT!

I was going the header route, but for $2k, Im still trying to find someone that has taken stock 98+ headers and installed a 3" collector / pipe connection. I might go this route with RT hi flows and B&B catback.

Anyone seen or know of anyone that has done some junkyard engineering on 98+ headers?
