TEC Stainless “De-CAT” X-Pipe


EURO 5 – A lot of models now have a cat in a different section of the pipes which is now welded in.  This pipe will not work on these models.  If you have a Euro 5 bike and are unsure, please get in touch.

Bolt-in replacement for the very restrictive standard exhaust CAT under the motor.

Our all-stainless and hand welded TEC X-pipes are unrivalled for quality, performance and price.

Designed to fit all watercooled Triumph Twin models (with cat NOT welded in the rear pipes) from 2016 onward including:

Bonneville T100
Bonneville T120
Bobber/Bobber Black

Speed Twin 1200cc
Street Twin
Street Cup
Thruxton 1200
Thruxton R 1200
2018 Speedmaster

Will NOT fit Street Scrambler

Will NOT fit Thruxton TFC or Thruxton RS as the catalytic converter is welded to the tail pipes on these models

Advantages include:

Dyno developed to give improved gas flow – giving better torque and power.

Vastly improved exhaust sound even with standard silencers.

Less back pressure and heat soak into motor to help with cooler running.

Unlike many other X-pipes on the market, our kit uses all 3 of the mounting points and standard exhaust clamps for a secure vibration free installation.

It retains standard heat shields and all “E”  compliance marks for a standard unmodified look – No problems at M.O.T testing time as emissions are not part of the test.

No drilling or cutting required and fully reversible.

Can be installed without a remap.  No problem as ECU will adjust.

You can use with Triumph’s uprated Vance & Hines maps to release even more power and smoother running on 900cc motors.

Can be used with all types of standard, TEC and Vance & Hines silencers.

TEC de-cat is used by many Triumph dealers and owners all over the world.

Please note you will need new front pipe to cylinder head crush gaskets.  All the other gaskets are re-useable a few times.

EURO 5 Bobber & Speedmaster – You can potentially fit this x-pipe on these models but ONLY if your bike has an exhaust system where the mid pipes are not welded to the cat.  This is only on some of these models, you must check before you purchase.  It will not fit any other models of Euro 5.

Excellent service, customer consideration and product 10 out of 10 well done.

Decat X pipe for speed twin 1200 2020

A real b*tch to fit, it's not easy to get the downpipes off due to the link pipe which makes it a 2 person job. Also getting the clamps back on to the rear exit pies from the X pipe is fiddly as hell.
However keep at it as it will be done eventually.

The reward is worth it, much better throttle response and acceleration, a lot less heat build up on your legs and sounds louder and better.

Stephen Sammons

Great fit and makes the bike run alot smoother

De-cat x pipe

Not fitted it yet but the quality is superb, ive watched the video and it looks simple enough to fit, just waiting for some free time, can't wait to hear the change in the exhaust note

Ray Charrington

Really gave the bike a cleaner, more responsive acceleration.
