i made an alteration to the resonator so that i would have more back pressure. because since i already had my resonator previously removed, i had to put it back in because it was too lodu without it. so i basically left 2 inches of the pipe that i used to have there extending into the resonator. its kind of hard to explain, but there is about 2 inches long of the old pipe sticking inside the back of the resonator(on the side towards the trunk)

i think it is 2.5 inch pipe but im not 100%

and it might void warranty i dunno, but im going to put it back in t lease end.
