Our Monster Pipes feature heavy 16 gauge steel tubing and measure a true 2.5" in diameter. The 1.75" header pipe continues inside the larger outer body to maximize scavenging pressure resulting in significant performance gains and reduced discoloration. Each set includes removable louvered-core baffles with billet aluminum end tips. The pipes have the larger bore O2 sensor bungs and are supplied with reducers for later model 'slim' sensors, as well as plugs for bikes not running O2 sensors at all. Mounting bracket and necessary hardware also included. Models with floorboards may need to shim right floorboard slightly to clear front pipe (no more than 1/2" max - our Forward Control Adapter Plates make excellent 'invisible' 1/2" black shims).
These pipes are supplied in raw steel, or with ceramic High-Temp powder-coated finish in Sterling Silver or Satin Black for an additional $300. In some cases we may need to send pipes to be coated once you have ordered, so please allow up to 3 weeks for us to ship coated pipes.
For use with Evolution and TwinCam engines. These Pipes are not legal for sale to California.
