Default Livernois GXP, Exhaust, CAI, Tune Results 410 RWHP!!

We recently installed a Corsa catback and "X" style crossover pipe on our 2009 G8 GXP. We put the car on the dyno to get results from just the exhaust, the exhaust and a tune, then the exhaust, Rotofab CAI, and tune.

For the small amount of mods, we are happy with the results. Now we just need the weather to stay nice so the track can open.

Stock Baseline 371 RWHP / 382 RWTQ - After Corsa 383 RWHP / 384 RWTQ



Corsa Exhaust & Livernois Tune 396 RWHP / 401 RWTQ



Corsa Exhaust, Rotofab CAI, & Livernois Tune 410 RWHP / 410 RWTQ



Here is a video of the car at start-up and idle, cruising at 30 mph, 70 mph, the 1st-4th gear WOT. (excuse my slow shifts )

and a video of it on the dyno with the Corsa Exhaust

Not bad for the stock exhaust...hehe.

I'm thinking that there won't be too much in the header swap...as the stock cat setup is the bottle neck with the stock OD tubes.

Probably won't do longtubes, because we want to keep it quiet. If anything it will get shortys.

Anything's better than the stockers! still some insane #s for hardly being modded. I read on the GRRRR8 forum this was a fairly conservative tune as well. The curious side of me wonders what an aggressive tune and a nice set of AR or Kooks Headers will do!
