You will all have to tell me how your extractors go guys, mine are still sweet, glad i got HPC coating, just wondering i got a hi-flow cat on my system, do you think i would be losing any power considering its a 3" cat, he just downed it to my 2.5" system i got, would i have got any power increase at all?
Also gotta get it fixed, either the muffler or cat is rattling under there like a B&$%#. Does anyone notice a sucking noise from extractors, or air noise?
Also any difference in havin a resonator or muffler on your system, he put muffler on before the cannon, but last system i got on my old car he put a resonator, sorry im a noob
