TEC Stainless “De-CAT” X-Pipe
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 from 2016 onward including:
Speed Twin 1200cc
Thruxton R 1200
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
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.
Fitted to a Speed Twin. A well made bit of kit that aligns all the fittings up perfectly. Take the on-line installation videos with a pinch of salt, there's a bit more to fitting this than I've seen on YouTube but they are okay as a guide. The Haynes manual was also a big help for torque settings and the correct order to remove and install parts. Can be a bit fiddly as Triumph definitely go for looks over ease of maintenance and a decent tool kit is a must. A lot more free revving now, sounds a lot throatier and up a few dBs from the cat, tested using the Decibel X app.
Works like a dream. Bike feels and sounds so different. Would highly recommend. 👍
My 2017 T100 no longer sounds like a vacuum cleaner. Removing the cat releases just the right amount of volume and is easier to move around in the garage and on the road. Its a subtle upgrade but you can feel the difference. Perhaps also smoother fueling and a bit more engine brake when shifting down. Sounds better across the rev range but particularly at tick over and high revs.
Fitting is a pain, if you don't have a lift get ready to roll around on the garage/shed floor for a few hours. Only needs basic hand tools though. Take your time and all will be fine.
Really well made product & postage time to Australia very acceptable. However, beware if you have a 2021 Euro 5 spec Bonneville. The cross pipe isn't meant to go on. The mid pipes on the cat are welded to the cat. I will find a way of getting it on my bike tho. I suggest maybe making copies of 2019 mid pipes to aid the fitment of this one. Overall a great experience dealing with Tec. I will be back for more mods. Keep up the good work.
X-pipe for Street Twin arrived securely and safely packaged. I was surprised that it arrived so quickly as clearly despatched close to payment. Love the quality of manufacture as it looks robust and beyond fit for purpose yet lightweight and thoughtfully constructed with gas flow in mind. Fitting does require some effort as frame and other components require loosening. Don't let this deter you as it sounds and performs beautifully.
