Are Test Pipes Legal

Post by bails74 » Thu Nov 09, 2017 8:24 pm

I've just had installed a HKS Hi Power exhaust. It sounds way better than stock but I wouldn't mind it a bit louder. If I got test pipes installed, would it pass a WOF?

Think you just have to be under 95 or 97 decibels at 2500 - 3000 rpm to pass wof standards.

More than likely wouldnt get tested unless it obnxiously loud

Yes my guess is you'd pass WOF. Though be careful which test pipes you install because 90% of them will make a dual exhaust like the HKS super raspy (tinny sounding). For best results i'd suggest either Motordyne ART pipes or a set of high flow cats (HFC). Best of luck.
