My friends bought a cat back for his car (magnaflow). The gave him a free high flow cat3in. His cat is bad u can telll... smells like bad eggs.. Does anyone make a aftermarket Y pipe that will bolt up to his manifolds. His car is bone stock

 

what year car is this??

the LS1 equipped cars (this forum) are dual cats

LT1 cars from 93-95 were single cat...and some 3rd gens were depending on year and engine

 

98 Ls1 Trans Am

 

Well it has 2 cats and neither one of them are 3" They are 2 1/4-1/2". There is no y-pipe made for factory manifolds that is 3"

BEWARE this guy doesn't know what he's talking about.
98-99 have tubular manifolds. 00-02 have cast iron manifolds.
They are TOTALLY different and one y-pipe can NOT fit all years as he has stated.

 

ok thanks
