Dyno numbers with bolt ons/dod tuned out

[VanNuland39]

I recently had my 08 gt tuned at Wicked 1 DNR in Fremont, CA and these are the numbers that they were able to get. Mods are 91 tune, Vararam CAI, JBA shorty headers with stock cats/resonators, x pipe on stock pipes, Badlandz electric cutouts after cats. The interesting part is that the red line is with the cutouts closed (so the exhaust is factory quiet), and the blue line is with the cutouts open (so the exhaust is just about straight pipe loud, with cats/resonators at least) These are with stock cam, converter, and differential.

Blue line is HP, red line is torque.

[STL_G8GT]

Blue line is HP, red line is torque.

No - at the top it shows each run horizontally - run 5 is red vs run 6 is blue.

Interesting - cutouts gain anywhere from 5-10hp & tq in the power band pretty consistently, and then, of course, extends that increase further up the rpm range.

Nice to see a real number associated with factory exhaust restrictions on a mildly modded / bolt-on G8.
