I have one nearly new (covered less than 3000 miles) Blitz Nur spec RX exhaust system.
I bought this system from Nic but it's too restrictive for my single. I can't make more than 427bhp, so it will work well on a BPU car but nothing above that.
The car is very quiet with this system. When I say very quiet, I mean I've heard louder electric cars
It does still sound good though, typical straight 6 burble and on boost it sounds awesome.
I'm after £400 but if that's too much make me an offer.
