Finally got round to fixing the bung on my Blitz Nur Spec S backbox after 2 months! Drilled hole in tailpipe for bung screw fixing but as suspected there is approx 2 to 3cm gap between bung & tailpipe. As Iv read on here, others have either used exhaust wrap (wears out over time with heat) or fixed 2 bolts as spacers etc.

I drilled a small hole in edge of bung & fitted a small bolt & nut to act as a kind of wedge for a tighter fit. Needed to file down head of bolt as it was a little too big for gap. A couple of washers, nut tightened hard & a permenant, discreet fix to a possible irritating rattle! This small bolt never needs to be removed & is hardly noticeable.

ps Hate the dam bung though, as well as the fact car felt down on power, it lost its growl & sounded like poo Itl only be for quiet trackdays & when family are in the car on long journeys
