I'm trying to get my car ready for smog. The car came with BBk L/T headers, O/R x-pipe and a catback. I want to know if the stock H-pipe from a 99-04 GT with manual transmission fit my 98' cobra if I replace the headers with factory exhaust manifolds or shorty headers? Any input or help highly apreciated. thanks

 

You are in Cali and facing the exact issue of which I am debating how to face

I know the LT's are not gonna pass, but you know that already. I am not even sure if the shorties would work, but I know that some will.

Wish I could be of more help

Good luck and welcome to MF's, Jazzer

 

Per various catalogs it seems that the '99 to '04 GT pipe will not fit your '98 Cobra, however a '96 to '98 GT pipe will...

 

JBA makes a shorty header called cat4ward (http://products.jbaheaders.com/cat4ward.asp) which is 50 state legal I just installed them on my car and got the carb sticker with them. As far a the x-pipe I really don't know, But you could try and contact Racers Edge Tuning in Downey, CA ( www.racersedgetuning.net). They have a complete parts department. I know the guy I used to have work on my car had 04 cobra x-pipe laying around in case someone needed one for a hefty price of course. Good Luck it's tough in California.

 

Thank you guys for all the info I really appreciated. I'll look into those headers your talking about snakelover. Thing is I have a 01 GT oem H-pipe in my garage. Guess i'm gonna have to do some custom work to make it fit lol

 

The hanger locations are different from 96-97 to the 98-04
