CB450 2-INTO-1 EXHAUST

Omar's designed this system (with the aid of master fabricator-Larry Conner) because there is no cool cafe exhaust available for CB450/500s. This 2-into-1 megaphone exhaust was not specifically designed with performance in mind (gasp) but we're sure performance gains will be realized over the stock system. Omar's is not going to get dyno readings to prove this point. You will find the megaphone reasonably quiet. The core is straight through with rearward facing louvers oriented in a spiral pattern. The packing is stainless steel wool, which never needs repacking. This system was designed to be used with rear sets. WARNING, this exhaust will not fit with stock foot pegs. It was configured to clear oil drain plug and center stand (We're big believers in center stands-they make working on the bike so much easier). If you are going to use this pipe, bend and shorten your center stand's foot operated arm-it no longer needs to curl out and around an exhaust pipe on the left side.

CB450 Jetting with 2-into-1 pipe system This is real basic information which does not cover all jetting variables-be cautious about jetting on your own if you don't have experience.

Stock engine - 130 main jets with stock exhaust and stock air cleaner boxes
Stock engine w/Omar pipes - variable not tested

Mod engine w/Omar pipes - 140 main jets
