I want to upgrade my current standard single pipe exhaust system to a long primary 4-2-1 or 4-1 system, to allow for future tuning. I am looking for a R3/4/500, SLR, Powerspeed, EBD, Simpson etc. Preferably with a cat as the car is 2005, but happy to consider exhausts without. Please let me know if you have anything tucked away. Thanks Julian
