TEC Fang 3-1 Full Stainless / Carbon Exhaust System – Trident 660 / Tiger 660 – Euro 5 models onward


A Tiger’s fang is almost as defining as it’s stripe.  A symbol of aggression.  Bared when ready to attack.

The Tri-dents means Three-teeth in Latin.

After hundreds of hours of development, the TEC Fang is now ready.

IMPORTANT – This exhaust is designed to fit without lower fairings/cowlings.  You may be able to fit with lower fairings with small modification but we cannot advise on this.

This is a race-line exhaust and not E marked or TUV approved.


The Fang may be our first ever 3-into-1 Exhaust System but that doesn’t mean we have deviated from our 4 fundamental tenets for exhaust design on our latest project.

Just like all TEC systems, the Fang had to –

Make your bike look much better.

Improve performance.

Sound fantastic.

Save a significant amount of weight.


All of this while still working out of the box with the stock ECU and no remap.

We were heavily restricted by the Euro 5 tune on this bike, but we have still been able to make some small power gains.

Power & torque are improved right across the rev range.  Seeing approximately 1bhp gain at 4,000 rpm rising to approximately 3bhp gain at maximum rpm.

The Fang stands apart from most other systems for these models with it’s longer mid-section – giving improved mid-range torque.

Full 304 Stainless Steel pipework construction.  Finished with a weight-saving carbon capped end.  All hand Tig-welded.

Spring fitting tool is provided in the kit.  All necessary parts are included, even a set of 3 official Triumph header gaskets.  If you lose or damage them, spares can be bought from your local Triumph dealer, part number -T2200854.  We recommend watching the full installation video to avoid damaging them.  We also stock them, click here to view the listing.

Fang 3-1 Exhaust : Excellent quality, great value, looks & sounds superb

Well made great looking product which sounds fantastic although there is no noticeable power increase. Tig welding is neat and precise, overall finish is exceptional.
Reasonably easy to fit but make sure you follow the written instructions not just the You Tube video as point 8 is VERY important to clear the sump casing. Don’t tap the down pipes firmly into the collector box or fit the collector box springs before placing a packer behind the sump casing and only then secure the silencer, or like me, you will regret it.
Really good value for money at this price point as I could see no point installing £1000+ pipe on a £7K bike, well worth waiting for.
I would highly recommend tec bike parts for the Triumph Trident 660

Fang 3-1

This is probably the best exhaust currently available for the trident 660. Not only does it look really good and sound even better, it's much cheaper than the competition, but quality doesn't feel compromissed.

Installing took a couple of hours and it was a bit tricky getting everything to fit properly, making sure the exhaust doesn't touch the oil sump and hit the swingarm or rear brake. After the first heat cycle everything now sits perfectly and construction feels solid. I have zero worries that the exhaust could move and hit anything.

I can't express enough just how good this exhaust sounds when riding, and it also looks so much better than stock. For anyone just wanting a high quality, priceworthy exhaust for the trident 660, this is the one to get


Great service. Arrived quickly and sounds amazing

***** WOW ***** Fang 3-1 Exhaust

This exhaust is amazing. Just what the bike needed to finish it off. Easy to fit. Looks incredible and sounds pitch perfect. It even pops and crackles on the downshift. ????

Fang 3-1 Exhaust review

What can I say another excellent product from Tec. The sound is "awesome" and a must have if you own a Trident (Race exhaust level with baffle installed). You cannot buy a better exhaust for the money and a complete bargain for a full system of this quality. Takes 2-3hrs to install if you take your time but well worth it when finish.
Totally transforms the look & sound of the trident in to a 'Beast'. Order yours today you will not be disappointed.
