I hv a 94 ls and im putting in a gsr motor, can i use the stock header for now or do i need to buy a gsr header right away. Need info pls!!!!!!!!!!!!!!!!!

 

Since you're not changing the exhaust, Yes you can use what you have.

 

if you used a gsr header it would not fit correctly because of the length of the catalytic converter. keep the LS exhaust manifold until you are able to buy a header, test pipe and modify your exhaust length to have it all fit right.
Good luck

Thanks I appreciate it. I gs If i go with and ls header 4 - 1 wud not be a problem. I gs later i will go with a full cat back exhaust.

 

Thanks again.

 

Wut do u recommend i go with. And where do i get the test pipe. Thats the small extention btwn the cat and the collector right? So shud i go with a full cat back for the LS set up.

Buy the exhaust to replace the current one, being a 94 LS, not to match the motor.

And a testpipe replaces the cat, which is pretty much pointless n/a.
