what company makes a really large pipe exuast system i just bought an 84 z28 and it has a huge exaust on it in to a big flowmaster muffler

 

what do u call really large? why dont u take a tape measure to it.

 

IT LOOKS TO BE 4" I WAS TOLD IT WAS A COMPLETE FLOWMASTER EXAUST SYSTEM BUT I HAVE NEVER SEEN A FLOWMASTER KIT LIKE THIS FOR SALE ANY WERE

 

mufflex maybe.
whats under the hood. sounds like it might be fast?

 

there used to be a company in the back of my hot rod magazines that made a custom 4in exhaust just for fbody's...i cant seem to recall the name..if i come across it, ill be sure to let you know...

and i dont think flowmaster makes a 4in...
