After many sleepless nights figuring out which exhaust would best compliment the Whipple 2.9, I decided to purchase the Dynatech system with the Magnaflow axleback. I could not find any sound clips with this setup so I had to just gamble and hope it sounded good. I wanted a deep sound that wasnt very raspy, but quiet enough to hear the whipple. I think this combo works perfectly. After each part I put on the car, it goes to the dyno to see if there is any improvement. I will say the fit and finish of this kit is perfect. Now onto the results. The car only has a Whipple 2.9 with stock boost, 72lb injectors, and the Whipple CAI. Has stock TB and pulleys. Honestly, I did not think I would pick up much gain, if any at all. I mainly just wanted the sound. But with the help of Lethal Performance and Jon Lund, these were the results...
