I took my car to a dyno a few weeks ago and ran the Whipple cal. I ended up with 663/521 (SAE)
I had Pypes headers, off road pipe, factory resonator, and Flowmaster axle back which everyone said was a power killer (the Flowmasters)
So, I swap the resonator for a Magnafow competition cat back. Now I have an X-pipe and the Magnaflow system. Well, it was too loud so I added two Dynomax race bullets. That is where I am now.
Went back to the same exact dyno today and got 663/501(less tq) again, but with a worse looking curve than before I swapped exhaust. I did turn the knock sensor feature off this time with the Whipple tune.
