CB450 2-INTO-1 EXHAUST

 

Omar's designed this system because there is no cool cafe exhaust available for CB450/500s. This 2-into-1 megaphone exhaust is reasonably quiet. Includes all brackets welded on for easy bolt-on installation. Our "new" megaphone is made of stainless steel and 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. 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. 

Includes high quality clamp and 1 can of high temp black or silver VHT ceramic paint. Chromeable steel.

OMARS XHAUST OPTIMIZERS ARE AVAILABLE NOW

OPTION: 2 EXHAUST GASKETS

Omar's exhaust pipes use proven racing technology 1-3/4" diameter pipes. The stock Yamaha pipes were only 1.15" ID. Our pipes improve flow by about 200% over stock for increased top end horsepower. The XtremeXhaust Optimizer™ kit fattens out the power band with a bunch more power and torque over the entire useable RPM band but the biggest gains are in mid and low range.

 

These EPO inserts fit between the head and exhaust pipe. The sleeved portion of the insert reaches into the port and "fools" the exhaust port into improving valve flow. It also reduces cylinder head heat retention by filling the back-pressure gap (black area) previously filled by narrow stock pipe. A cooler head and hotter exhaust gases make more power. After an exhaust valve opens, the exhaust pressure wave rushes down the pipe, hits the end of the pipe, then turns right around and pulses back toward the cylinder. These narrow diameter port inserts minimize some of that reversion wave in anticipation of the next outward wave. This improves low and mid range carburetion efficiency. You will find carb tuning for maximum output is much more precise. This insert works wonders with stock engines but it is highly effective with tight lobe center acceleration cams in high performance engines. They "bolt-in" as you tighten pipe flange.
