ok this dude has a 2001 ls1 trans am and i have a 96 lt1 trans am, and he is selling me everything headers back, the ypipe and the borla cat back, and he told me a guy said that the ypipe wouldnt work on my lt1 cause ls1 y pipes are different!! is that true, ok will the catback even work on mine ?

 

I don't know about the y, but the catback should bolt right up.

When SLP first came out with the Loudmouth, it was only made for LS1 cars but it bolted right up to my '97 with no modification and no extra parts needed.

 

The y- pipe won't work without modification. The driver's side LS1 header angles towards the driver's rocker panel, where as the LT1 headers both point strait toward the rear of the car. The cat back however, as stated above, should work just fine.

 

don't buy LS1 headers! very different. The only thing that will work without modification is the Catback

 

Oh no no bro I just installed long tube pacesetter headers new on my 96 lt1 and an orypipe that came with it, I am buyinh his cat back and he is throwing his ypipe in with it and I was just curios if it would fit lt1 cars or not, I am NOT using it I have a brand new one on my car with the headers!! I. Am just buying his exhaust for really cheap and. All I need is a couple of parts off it, I already have a borla catback but I messed up my I pipe so I. Was gonna buy a new ipipe from borla for 200 but this guy is selling me the whole catback plus ypipe with brand new borla tips for 200
