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.

Great quality product and great service

The team were super helpful in answering all my questions and super quick in preparing my order. It made it for England to New Zealand in exactly a week despite all the dramas of COVID.
I haven't fitted it yet but having close look it's excellent quality and exactly what the website shows.

Great stuff will definitely be getting more from TEC in the future
