Atleast they aren't starving their engine like you are with the 2.25" piping on a car that came with 2.5" stock!

 

they both do not sound ricey

 

I have heard the Vibrant in person and with an added resonator sounds great (LOUD) but good! The Hahn I have heard clips of, and it sounds good!

I would still go with a 3" over a 2.25" anyday!

 

anyone can text me at 732 620 6499 or pm me im going out for thee nigfht

 

my only complaint with them is that they are too much piping and sound ricey under full throttle. nice otherwise.

and my 2.25 makes my car better than most stage 2's...if you look at my times. so thank you. And its a lot less restricitive than stock, believe it or not. Stock LOOKS like 2.00" at some points in it.

 

2.5" stock is kind of misleading . It's more like 2.5 in some areas with crush bends , down to 2 -2 1/4'' in others. I'm sure that GMPP exhausts flow better than the stock SC's .

SS/SC dyno before and after GMPP exhaust.
