4″ Quiet Exhaust

New 4″ 3 box quiet exhaust, cant believe how quiet it is now, no more noise worries at any race track now, it sounds like a milk float. Seriously I reckon its about 93db on idle, haven’t tried it down the road yet. Quite a size that rear box though isn’t it! Also the wastegate is recirced back into the exhaust and I have the option of having it open to, sweet.
