haha yeah that's how i was at first when i installed it. but with the catback its actually more noticeable even at lower RPM's with a nice growl, yet still quiet enough to drive to.. then at 3.5k+ RPM it roars. welcome to the twinloop gang buddy :D how much did the catback set you back? and what other components you have in the catback? reso? new highflow cat?
