Do you need to tune your vehicle with a wide-range AF ratio sensor? There's no need to drill a hole in your exhaust and weld in another bung.  We now offer U bend eliminators with two O2 sensor bungs - 1 for your production factory post O2 sensor, 1 for your wide-range AF ratio sensor for tuning purposes. Replace the restrictive "U-bend" on your factory exhaust with our pre-made unit, increasing horsepower and throttle response. We even supply a plug to insert into the unused bung during normal operation.  When you're ready to tune, simply remove the plug, install your wide-range sensor and you're ready to go. Your factory exhaust system has a restrictive section of pipe which causes added backpressure resulting in power loss. Modifying your car with a different intake system and/or smaller pulley only makes this restriction worse. Free up this restriction with our U-Bend replacement. Requires welding.

NOTE: Typically, 1997 - 1999 cars will use the SHORT VERSION & 2000+ will use the LONG VERSION. To insure you get the one you need, measure from the end of the CAT to the flange. Our SHORT Version is approx 8" & our LONG is approx 10".
