"
Key points*
-No power Commander needed, works with stock ECU and is within all parameters
-Gain of 4+ foot pounds of torque and 3+hp on Dyno
-Drops almost 26lbs off of the stock system
-Sounds amazing, with all the pops and crackles, definitely on the loud side but I love it, did not put the baffles in.
-Too loud and deep to register on phone MIC, will try to upload a proper sound clip soon."
