Just went to the muffler shop this morning and let them do a test drive with me of coirse, and said: the noise too much rasp is because my setup is pretty much straight pipe. And the RPM issue is the tune. There was no leaks or problem with the pipes. So they recommend getting an axleback with muffler (?) And put some resonators on the downpipes. Im still contacting trifecta tune but they havent respond yet.
