Hey
Who in Auckland knows their stuff re getting an exhaust system to sound better. I got a 2.5l straight six ( old school non BMW I confess) with twin system straight pipes through to rear mufflers ( in mint condition). Sounds great when your above 4000rpm but below that it's pretty nana.
I don't want it too loud and I don't need better performance really just want a good resonance / crackle. Who in Auckland knows is smart / can think outside the box as far as exhausts go. I'd probally take it to Woof on Dom Road - but only cause it's close
cheers Rob
