My 91 trans am convertible (305 TPI Auto) needs exhaust... lost the muffler and pipe that goes to the muffler is rotted.......



My parts car a 88 GTA 350 auto ( was TPI now a carb )
Has flow master exhaust but the y pipe looks to be 3" diameter all way back.....
Convertible looks small....??








Can I swap the exhaust from y pipe back.......
Flow master exhaust on small y pipe in my convertible....
Or do I need to change exhaust manifolds and y pipe....
Can 350 {1988} manifolds bolt to a 305{1991}..??
Thank you in advance

Yes

Only if they're messed up somehow

If both are TPI, then not only are they interchangeable, but also AFAIK they are the same
