I bought the catback...installed it...didn't like it....cut the tip off...put a wider diameter tip on it...didn't like it even more (it resonated at 40 mph like a bottle) and sold the damn thing. Put the OEM back in...nice an quiet but had appreciated the sound of a friends VX with the PV version 1 muffler and started again. Bought the PV muffler only..took the OEM off and installed it. No bottle effect..just a good sound and now with the SC..a necessity! Thanks to CatmanV now a.k.a VX man for the ride with the PV original.
