TEC Stainless “De-CAT” X-Pipe

(366 customer reviews)

£89.99

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.

NOTE – This product now comes with a more shiny finish than shown in the picture to better blend in with headers.  The part is still hidden from view when fitted though.

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.

The product is strictly for off-road/race/demonstration use only and is marked “NOT FOR ROAD USE”.

Gives my Bonnie just what it needs

Fitted a coupe to my 2019 new to me T120 sounds so much better even with standard pipes. I’ve fitted two of these and have only just learned that put the clamp and seal on the rear flange of the coupe then push in the rear pipe

De-cat. X-pipe

Wow so responsive

The x pipe is well made and fits perfectly and it certainly makes a difference the engine revs easier and the revs fall back quicker it’s how the bike should have been when made.its a bit lighter not that you can feel it really and it releases a bit more noise and I think it’s makes the t120 sound very nice just loud enough all in all well worth the money.but I would not say it was an easy fit not due to the x pipe but those horrible stupid clamps under the back of the engine that join the exhaust.but it was definitely worth it ⭐️⭐️⭐️⭐️⭐️

De Cat X pipe

Excellent service from TEC. Fitted to my T120 with standard cans. Helps with fuelling and pick up is a lot smoother. Not as loud as I was hoping though.

Does what it says on the tin.

Ordered a De-Cat X pipe from TEC. Best value on the market that I could find. Well made and a good fit. Uses all the OE mounting points. Clearly well made and engineered. Once the engine learn was carried out the bike appears to pull better low down and mid range. Sounds the same just more audible at higher speeds. Removed a couple of kilos from the bike too. A good upgrade. May be worth ordering new front pipe gaskets when you fit this part as they are fragile and it is a tight fit. Also I tapped up the frame tubes which judging by the marks left on the tape from the exhaust during fitting was a wise precaution.

Better Than Expected. Excellent Quality and Finish

The product looks even better than in the pictures. The welds are solid, and the chrome finish is beautiful. The photos don’t do it justice. Delivery was excellent. I’ll install it in the next few weeks and see how it performs."

10 out of 10 the pipe fitted as per your video but took me a bit longer 😊. Has made a difference to sound and power delivery. Really pleased. Delivery was fantastic 👍

Just right!

Bought late last year for my 2016 Thruxton 1200 but only recently had the chance/time for the installation. Fairly straight forward but struggled to seal on one side. Fitted new triumph crush washers but they didn't! so put one of the originals on which worked. The exhaust note is now deeper and a bit louder at tickover but has a lovely bark when given some beans. Pickup from low revs has completely eradicated the slightly snatchy throttle behaviour and it feels more rev happy and smoother from low down and through the rev range. The bike feels quicker but that might just be me. Altogether really happy and at the price is a bargain! Another great buy from TEC Bikes.

Easy mod to make

Item is well made and was easy to fit. You need a paddock stand. Changes the sound to a nice deeper burble without being offensive. Also you lose a lot of mass when you take the cat off. Fitting was straight forwards, there are plenty of videos on youtube on how to do it - but if you are just methodical and remove things until you can get to the original and then, as the Haynes book of lies says "refitting is the reverse of removal"

x-pipe

well made and easy to fit and really does make a big difference to engine response at low revs in town plus a much meatier sound from the stock end cans so what more do you want .

Good price and seems to do the job

So I’ve not done many miles since putting the xpipe on but it sounds a little louder and deeper but not by much. The bike is running very smoothly with it on. Apparently it was a pig to fit as it wouldn’t line up (I had it done by an independent Triumph specialist who is used to doing the job) but it was very light and over half the price of another alternative and from a UK company rather the Europe so that’s a big plus. All in all happy with it and good value for money. I will continue to use tec 👍

Tec D-cat X Pipe. Speed Twin 1200

I've had this item for quite a while and I have been steeling myself to face the job of fitting it. It's a pain in the A*** to fit, I have previous experience fitting one to a T120. It's even worse on the Speed Twin. The Chinese puzzle of the header and balance pipes takes a bit of solving. Read the Haynes manual and it all fits perfectly. Once fitted, you will be amazed how much more rideable the bike is, especially riding round town, less jerky and lumpy, being able to stay in a higher gear instead of keep changing down. Out on the open road, give it some beans and listen to the glorious tone of the exhaust (even with standard mufflers) as you rocket into space. It's well worth the day I spent fitting it. This and the Tec Progressive front fork springs are essential for Speed Twin Owners. Fit yours now! I am waiting for the Men of Tec to market some stainless Pea Shooter silencers? John Essex.

De cat X pipe

Now fitted to my T120 (2018) and very pleased. Have been pondering for 12 months and wish I done it sooner. Local dealer fitted for me, took 3 hours but now smoother at low speeds and a more throaty (not excessive) noise. I chose Tec after reading countless reviews also my dealer said he had fitted many Tech parts (not decat) and quality excellent. A well worth while upgrade and very quick service (24 hours) from the Tech team

This X pipe was a very easy fit and is very well made. It has given my speedmaster a nice bark to the exhaust sound and a very nice bumble on the overrun. Delivery was very fast too. Excellent service 5 stars.

t120

it didn’t fit very well on t120, there are two places for bolts on x pipe but they are not distant enough from each other, so I had to screw only one. which is not a major problem, pipe still holds very well.

Excellent

This was the second order that I placed with Tec and same with the first one it was great! This time was for my second bike, a Triumph Bobber, and it was the decat x-pipe. The delivery arrived soon after the order, it was well packed and although there was no instructions you can easily find a lot of videos on YouTube. The bike now breaths better and have a pleasant bass sound from the stock silencers!

Great value and produces a really good sound. Fiddley to fit, but that's the bike's design, not the product. Thnaks.

Xpipe

Great piece of kit, arrived very qickly, well packaged, just what I'd expect from TEC. Thanks for the video to fit it, it saved me a lot of heartache. One thing, I did wrong was, not put the exhaust clips on the xpipe, before I fitted it, even though they tell you in the video to do just that. My fault, but it really is a must to do, as its a pig to try and get them on whilst its been fitted. I'm really pleased with it anyway. Tec have never let me down. Thanks people
