I am in the middle of doing a LT1 swap into my '91 RS which had the 305 TBI. My question is will a 4th gen Y pipe fit with no problems ? I had a SLP Y pipe off of a '95 Firehawk given to me, and I really don't want to have to cut it up. I will also be using the stock LT1 exhaust manifolds too.
Thanks,

It will fit but make sure to match the y-pipe to the manifolds. 1993-1994 manifolds are different than 1995+ and SS or WS6 manifolds. You will need to make sure the manifolds are 1995+ to work with your Firehawk Y-pipe
