Eliminate the performance-choking catalytic convertor on your 2009-2010 YZF-R1 with the Catalytic Convertor Eliminator Kit from Two Brothers Racing. This seemingly simple cat eliminator goes in-between the OEM mufflers and the OEM collector pipe and will knock a few pounds off the weight of the R1 in addition to liberating a few ponies from the motor. Less expensive than a full system, combining this with a slip-on exhaust and a proper tuning will improve your R1’s engine performance. You won’t feel so much heat coming off the right side of your leg either. The pipe is constructed of mandrel bent stainless steel and bolts right into place.

Get one by calling TJ at 866.931.6644 ext 817. You can also email us for shipping and availability – send those to FORUM at RIDERSDISCOUNT dot COM with the subject line R1 CAT ELIM and we’ll get back to you right away.

Looking from what would be the bottom of the pipe upwards.

For those with an aftermarket self-tuning device installed on their bikes, the Two Bros Cat Eliminator includes a lambda sensor bug to accept the probe from either the Bazzaz Performance Z-AFM (http://www.r1messagenet.com/forums/showthread.php?t=4174) or the Dynojet AutoTune for Power Commander V (http://www.r1messagenet.com/forums/showthread.php?t=4144).
