Hi all, sounds like my back box is blowing quite loudly, although it does sound awesome when you put your foot down, the resonance through the car is deafening. Priced up a new one from nissan in gloucester and i`m not suprised everyone fits aftermarket systems, they want £346 for the back box, and for the whole system, its nearly £900!! So nows the time to get my s/s system. My question is mainly directed to Kev or BigPhill, can you recommend a reasonably priced system that sounds good but doesn`t intrude into the car and is the magnex system any cop?, how are you fixed for a fitting on saturday I`m desperate to get it sorted so any advice would be great.
