Hi Dmoff,dmoff said:
The Super Dragger is one of the most restrictive aftermarket exhausts. The loss of power I was mentioning was comparing it to other aftermarket exhausts like the HKS Hiper Muffler, Blitz Nur Spec etc etc..... The SuperDragger is very restrictive at the point at which it enters the backbox compared to other designs. I've seen cars make more bhp on the rollers just from changing from a SuperDragger to a Hiper Muffler.
I have a honda now but it wasn't always the case
