Decat X-Pipe for Triumph Motorcycles – Unleash True Performance & Sound

Unlock the legendary Triumph sound with our Decat X-Pipe, designed specifically for 2016–2021 liquid-cooled Triumph Modern Classics. This direct catalytic converter replacement transforms your bike's character—boosting performance, shedding weight, and revealing the raw, parallel twin exhaust note Triumph riders crave.

Crafted in California from 304 stainless steel, each Triumph X-Pipe is precision TIG welded and mandrel bent for optimal exhaust flow and durability. By eliminating the restrictive factory catalytic converter, this decat pipe improves throttle response, enhances mid-range power, and delivers a deep, aggressive exhaust tone.

Note: Tuning is recommended. See our Tuning Guide for more details.

For Thruxton RS: The X-Pipe for the Thruxton RS model will include a new left and right mid-pipe, since the factory mid-pipes are welded onto the catalytic converter for these models.

2021+ (EURO-5) models: Some 2021+ models may not work with the X-Pipe, since newer models have the intermediate/mid-pipes welded onto the catalytic converter. To verify this, check under your bike from the front of the frame to confirm if your intermediate/mid-pipe is welded on or fastened by a band clamp. Please see Competition Headers for this 21+ application.
