We have tested the differences between 2 1/2 and 3" multiple times. When you have comparably flowing systems, you will see little to no difference in power between the 2. If you have a corked up 2 1/2" exhaust, the the 3" will show a very large improvement.
I prefer 2 1/2" over 3". Its easier to manuever around the body, and rear cradle. But ONLY if its a very free flowing system.

Quick question, with that kind of power that this car is putting down, how much of a difference would 2 1/2" exhaust compared to 3" exhaust make for hp and tq?
Edit: I think Photobucket was doing some site maintenance when I clicked on the link. Looking forward to hearing her scream soon.
