I've now read the last few years of topics on people wanting to put a 4th gen exhaust in a third gen. Seems the going opinion is to put a flowmaster/SLP/Borla/whatever on instead. My problem is I have two 4th gen cat backs. One off my old (traded in for my vette) 98 TA WS6 and one off a 99 Camaro SS. They are both in good shape and would like to use one of them and save the $200-$300. Will also install the SLP headers I've had laying around for a year. Where can I find info on the mods to the cat back (brackets, hangers and 45 degree elbow) needed to adapt it to my 92 RS? Any help is appreciated.

 

i really couldn't find any hangers for my cat back (after I had to cut one off) I tried welding up my own, but now I'm just gonna go to the shop and have them do it

 

I would like to find this one out too....(4th gen exhaust in a 3rd gen). I believe it would work and there isnt any real weird hangers etc, but if you do find out I would certainly be intersted.

 

i know the muffler parts all go the same way,with the hangers and all,my old setup had a flowmaster from a lt1 camaro,and everything else would prolly be the same wouldnt it??

 

is there any diffrence in the exhaust at all besides the way it hangs in there? i always thought the muffler was offset just a little in the fourth gen's

 

The 4th gen rear section over the axle is the same the difference is from the manifolds to the axle. The 4th gen center section is a different angle before the cat I think it may bee too close to the passenger side floor board (hump) to work on a 3rdgen but its worth a try if you have all the componets.

 

so then from the muffler back it should work?

 

From the muffler back definitely works... here's mine with the muffler and tails from a 2000 WS6...

 

borgx....what did you use for the pipe between the cat and the muffler then, the stock piping?

By any chance is yours one of those "takeoff one's" I have seen for sale????

 

I already had the pipe from the cat to the rear... you could use stock, or in my case, I had a cat-back already on there that was WAY too loud! I know many people like them loud, but me and my neighbors were starting to fued... so I installed this muffler and install a cut-out at the same time so I can get LOUD when I want to... hehe

The only difference I ran into was the way the muffler connected the tailpipe to the driver side. 4th Gens have an "L" shaped hanger and 3rd Gens have a hanger that connects via a bolt. We cut the one off the original tail and used it on the new setup... easy fix...

Of... forgot... I had a friend give me this setup off his car when he installed a Corsa cat-back... this one is the same as the take offs though...

 

nice...thanks for the help
