ok you guys any one have this exhaust system.. if do how you like it and how dose it compare to tpr and trd

on a gts its about 5 whp higher which is above average. it's also slightly heavier than the stock exhaust. i dont have this for myself so i can't help you with the opinion part..but you can listen to sound clips of it (as well as several other exhausts) here...also included are dyno graphs, weights, tip diameter measurements and some other info as well
