My 1976 Pontiac Firebird Esprit with Summits 2.5 inch true dual alluminized exhaust installed. I have a video taken with my laptop computer so the sound quality is fair. I included pics of the system the day I installed it so you can see how nicely it fit with little fabrication.
My bad just noticed this thread, guess ill repost here.
350 with hooker headers running 2 1/4 true dual with flowmaster super 10's
Im going to be rebuilding and dropping in a 400 and running 3" with either 10's or 40's
A video of my car in 2010. At the time it had a stock LS1/4L60E, stock manifolds, hollowed out stock cats, bolted to a Bassani 2.5" true dual (x pipe) catback. 1999 Pontiac Firebird Y87 - YouTube
Wish I could see the viewing statistics to figure out where all those views are coming from. lol
Stock manifolds, to stock Y, no cats, to a 3" magnaflow mid pipe, up over the axle to a 3" sweet thunder muffler, to a 3.5" dump
ive got mac headers and matching 2.5" y to install soon, just need to get supporting mods first
