Hey mate, sorry about the super slow reply. Haven't been on here in months.
If you're still after the info, here it is: I don't have extractors or hi-flow cats, its completely stock except for the cat-back system. Its been ages since I put them on but if I remember correctly it was a twin 2 1/4" into a single 3" Manta system. It still sounds great
