The Tapout Blue Belt performance package includes a ported and polished throttle body, two K&N high flow air filters and performance downpipes to replace your factory catalytic converters. Help your engine breathe by giving it more air in, and a lower restriction path out. This performance package will normally produce gains of 100 to 125 whp, giving you 500 to 550 peak whp with 93-octane fuel on a DynoJet dyno, using SAE correction and smoothing = 5.
Catless downpipes do not meet emissions requirements and are intended for off road use only.
Non-EPA catted downpipes utilize ultra-high quality and high performance catalytic converters, that balance exhaust flow with effective emissions conversion, and are also for off road use only.
The EPA Catted Downpipes are legal for all states that don’t have CARB regulations.
None of our downpipes are available for sale, shipment to or use in California.
