Btw post sound or video clips of your engine sound!
Stainless Steel Bolts etc http://www.groveco.co.uk/ Steve What were the sizes of bolts/nuts you ordered from them? I have a 328 US spec car & will be changing out the exhaust also. The Stainless Steel is the way to go..Just don't know what sizes to order Mike
328 Mondial here (same engine and exhaust) but with a Stebro instead of the Tubi. The Stebro sounds great, is a little less bling (not polished), with good build quality and not too much resonance at idle. My Alfa spider sounded great, but this sounds better! My wife is accustomed to her S-class Mercedes so the Stebro is a little loud and raw for her - same for my 1 year old - but what do they know?
