Test pipe 87 GN

[Randy Hagins]

Still trying to find a 2 1/4 test pipe to fit a stock down pipe. I have a ‘87 GN.
Thanks!

www.kirbanperformance.com use to have them.
I would call Dennis to see if he happens to have one yet.

They have a 4 bolt flange to take to a muffler shop to have one made if all else fails.

Think stock is 2-1/2” for that test pipe ? ‍

my nos down pipe was just a tick under 2.5 and the one on randy's car was 2 3/8 , was wondering if heat cycles may have shrunk it a little , but 2.5 will be the choice don't think they make 2 3/8 or 2 7/16 pipe
