If I have headers do i have to change my stock exhaust?

sorry this may be a dumb question.

 

No need to change your exhaust... you wont see any improvement if you do.

 

You don't need to...but boy do they add to the whole look and sound of your car!

 

They totally do... really finish it off nicely. Plus, you may get 1-3hp

 

thanks again guys

 

so wait I'm not understanding sorry if i installed headers(OBX) which i probably would purchase I would NOT need to change the stock exhaust??

 

Correct... the stock exhaust is extremely free-flowing as it is.. so it almost makes aftermarket exhausts on this car a cosmetic/sound mod....

The highest gain I've seen on this car (well, CL-S, but same difference) was 6hp. That was one dyno. Everyone else has dynoed around 1-3hp max....

 

Did you mean the 6hp was gained from an aftermarket exhaust alone? Or with headers? I'm not sure what mods added 6hp.

 

You wont get 6hp... that was just a ONE TIME that happened on a dyno, so its not vaild...trust me. You will get 20-30hp from the headers though.

Get the headers, dont bother with the exhaust unless u want it for sound or looks.

 

Agreed.

 

I agree.....people over on the AV6 board think that an exhaust will net 8-10hp..........I have a TL-S exhaust on mine, I just can't stand the sound/look of most aftermarket systems........comptechs are nice, but I just couldn't justify spending that kind of money for that little hp, plus I didn't really want the added sound. If you are set on getting an exhaust, get the comptechs.
