PH2 172
Had a exhaust fitted by Prospeed friday. Was a stealth cat back with a decat and small middle box to make it pop and sound nice and raspy. They told me it would take around 2 weeks for the system to start making the sound i want due to it being decated means it will take longer to coke up the system. Iv covered around 600 miles in it already and still no change in sound still quiet lil rasp till bout 5k then after that sounds like a screamer pipe on a turbod car and still no popping at all. Anyone have any ideas or do i just wait another week.
