Had a Powerflow fitted. Was really nice when I first got it, but now it's just gotten too noisey and it's pissing me off. It sounds nice when you blat it, but unfortunalty it just rumbles to much when doing low revs.
Anyone know what I can do? Not a lot I guess other than take it to Powerflow. Just wondering if anyone has had previous experiences.
I thought that zorsts got quieter once they had 'coked' up a bit.
