Here is the first version of our 2.5" GTM cat back with some dyno results and some pics, The car made 308 RWHP and 261.1 RWTQ with adding 2 degree's of timing via the consult III. The 370Z counties to impress us by how well it responding the modification we are making. We will be finalizing the GTM ecu flash for the 370Z within the next 10 days and i have no doubt that we can get other 10 to 15 RWHP with some tuning .
We have another week to finalize our GTM 3 " exhaust then we will move to the turbo kit .
Stay tuned
