Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
The seller says the cat flange has a "gasket" that needs removing. I dont think this is correct, heres what Im seeing at the back of the cat, theres no way I can see to get that protruding part off this flange.... Its not what I would call a gasket either.
The note is great, wife doesnt mind it and it feels like a V8 should now, at full throttle though it does sound a bit ragged.
Headers and cats should sort that out. Next on the list?
