Does anybody know where I can get a 3" tailpipe specifically made for a 1994 F-body? I have a single exit 3" flowmaster that I need a tailpipe for. Also, does anybody know what glasspack mufflers sound like on an LT1?

 

I'm sure any competent exhaust/muffler shop could bend one up for you with minimal fuss. Or you could contact Flowmaster for a 3" pipe to connect to their muffler, as I believe they offer the single out setup as a catback system. Simply order the tailpipe from that system.

 

I got the flowmaster catbacks and when they installed it they had all the different tips there. I got the 3".....heck or maybe bigger chrome tail pipes and love it. I think they look great. Try and check your local exhaust shop too nearby they should have it.

 

Glasspacks sound like a$$. Instead of a smooth rumble from the exhaust you'll get a pop pop pop pop pop sound. Basically it'll sound like an old farm truck. I don't think you want your car to sound like a turd

 

Got any picture of the 88 Iroc, how much are you asking, and how many miles does the car have on it?
