Ok, i did a search and didnt really find a definite answer. im going to end up putting a borla catback on my 92. problem is the thirdgen tips look like ***. my question is, other than the hangers will a 4th gen setup bolt up (read: is the over axle pipe the same as on a 3rd gen). the i-pipe shouldnt be a concern because it will be connected to a mufflex y-pipe with a 4" to 3" reducer(hooker long tubes). ill be ordering the 93-95 single cat system. i just dont want to do too much hacking for $600!

 

i have a mufflex 4in from a 4th gen on my 88. its the sameother than hangers/brackets. i used to sell stock take-off ls1 systems to 3rd gen guys all the time. doit.

 

thats what i wanted to know. thanks a lot.

 

i had installed a new muffler a friend of mine had purchased for his 97 firebird onto our 84 z28 we had when i first got the car .........fit fine ...

 

i put a 4 th gen borla cat back kit on my 3rd gen and it was good but could never get the tips to line up the exact way i wanted. never could figure out if it was the kit or just me

 

The exhaust on the 4th gen is offset slightly, thats probably why they didnt line up.

 

I just put a 4th Gen Borla catback on my 85 Trans Am. I bought the muffler/tailpipe hangers from a 2002 fbody, it fit perfectly and the tail pipes lined up.

 

it will fit just fine but you must use (all the mounting parts) from a 4thgen too
