TURBO4LT Member 1,533 Member For: 21y 8m 12d Gender: Male Location: NSW Posted 28/04/11 10:58 PM Share Posted 28/04/11 10:58 PM Rear muffler was restrictive on mine, it sounded like it was going to explode over 370rwkws. Once I unbolted the rear muffler the boost came back in the higher end of the rev range.
