There's no denying the new 4-strokes provide great power delivery, but most folks will agree that, for off-road riding, low RPM response can be a problem. We've all been in situations where you need to lift the front end quickly to clear that nasty log or rock, but when you crack open the throttle, the bike either hesitates, bogs or stalls. And it always seems to happen at the worst possible time or place! Well after a number of years of trying everything from jetting kits to race fuel, we've learned the problem lies in a combination of restrictive intake and exhaust flow and a lean condition caused by the accelerator pump on FCR carbs.

The products listed here all address the off-idle bog seen with most new 4-strokes, but they also have the added benefit of increasing performance and throttle response everywhere. In addition to aftermarket exhausts, we're running everything listed here on our KTM's, Honda's, Suzuki's and Yamaha's with amazing results!
