2 into 2 pipes made by
The ID is 1.410" , the OD is 1 1/2", they are 35" long with a slight kick up at the end.
They have complimentary Theoretical Horsepower and Torque Peaks, so TPOs are not necessary.
EPOs recommended. These come with a stock-style removable finned clamp.
(Gaskets are available below).
XS Performance 1 3/4" Stainless Steel Head Pipes
2 into 2 Stainless Steel head pipes made by
The ID is 1.635" , the OD is 1 3/4", they are 39" long with a slight kick up at the end.
These do not have complimentary Theoretical Horsepower and Torque Peaks, so the EPO/TPOs kit is
recommended. These come with a stock-style chrome removable finned clamp.
1 3/4" "P" Clamps
1" wide, 1/8" thick chrome clamps with a 6 1/2" strap. For mounting MXS07-0758 without mufflers.

Exhaust Port Optimizers
They say imitation is the sincerest form of flattery. Having been so fortunate as to have learned from the Anti-Reversion Master himself, Jim Fueling, I have been working with this concept over 30 years, so it's not surprising I am able to offer a superior product.
Now an improved CNC version, including stock pipe replacement rings, with enhanced exhaust port flow, less heat radiation into the head, less reversion. Billet assembly, suitable for 1 1/2" to 1 3/4" head pipes. Bolt in.
"My clutch never slipped before!" -- UD
The Theoretical Torque Peak (TPP) will determine the operating range of your motor. Typically with stock pipes, this is at 1000 RPM below redline, sort of a built in rev limiter. On road racers, it is at or slightly above redline, so the motor will pull to redline. On flat trackers, it is 1000 RPM or more above redline, to give over-rev capability, and soften power delivery off the turn. On a 650, 1 3/4" head pipes give a TPP of 11,000 RPM-- Useless. Even on a 750, it is over 9500- useless unless racing. There is no free lunch-- you can only shift this powerband. Mid-range is what gets it done on the street. You can have your large OD pipes and still optimize the TPP for your displacement and RPM range. Each set custom designed and built for your application.
These inserts must be welded in the head pipes just before the mufflers or may be butt-welded to effectively extend the head pipes for a complimentary Theoretical Horsepower Peak

Using the principles of anti reversion, these limit the backflow from the exhaust
into the intake port during overlap. Flow bench testing has shown as much as a 53%
difference between outflow and backflow. Most effective with tight lobe center cams.
Improves low end and mid-range carburetion, especially with large head pipes.
For 1 3/4" head pipes only, best on 750s, stainless. Bolt or weld in.
