Building time: 3 to 4 weeks

Once Toce dropped the Razor Canister System, we revisited the 09-14 Yamaha R1's to see if we could run a shorty exhaust/slip-on without sacrificing performance. A unique alternative to the common undertail systems, eliminating the need to run an additional cat-delete and ultimately save overall weight as our baffled canister assembly itself weighs in at 3.2lbs!
Note that these systems require the deletion of the o2 sensor.

Constructed of Chemically Certified 6061-T6 & 6063 Aircraft Grade Aluminum and loaded with a 304 stainless steel spiral welded perforated baffle assembly + ISW Packing. These exhaust systems from Toce Performance are one of the company's best sellers, made right here in Manchester, Connecticut USA, and are hand-welded; comprised of all in-house designed and machined CNC components.  When paired with our ECU Flashing service + MWR Filter Combo, completely opens the bike up to its true potential while standing out from any other setup on the market.

Toce Exhaust systems are all designed for each application. No two systems are the exact same, nor are they generic muffler assemblies held onto bikes with universal band clamps. Each one is designed for its application and made in our facility in jigs, to ensure perfect fitment. This is why Toce Performance offers one of the most comprehensive lifetime warranty programs that offer more to its customers than anyone else in the industry.

Additional Components available for these vehicles 

Servo Eliminator
Allows you to remove the entire exhaust servo assembly without getting an FI light.

MWR High-Efficiency Air Filter
Washable, Reoilable, Performance filter with Maximum Protection and perfect design + fitment. The HE Filters specifically help with air turbulence and not only provide more equal flow to each cylinder, but reduce intake noise as well. 

ECU Flashing
A "mail-in service" Eliminating the need for piggyback fuel computers, Toce offers a same-day turnout ECU Flashing Service. Simply purchase the flash with the exhaust, and upon email confirmation, you'll receive instructions on how to mail us your computer. Remove the unit, send it to Toce Headquarters, and we'll flash it the day it's received, package it with your exhaust and ship everything out to you in one big insured box. 
Toce ECU Flashes include corrective fueling for all modes and on both the IAP and TPS Maps. With cooler fan temp settings, reduced engine braking, and unrestricted factory settings, you'll experience smoother drivability and more
