TEC Full Big Bore Stainless Exhaust System – CANNONS – Royal Enfield Interceptor 650 / Continental GT 650


Available for the first time as a full system – we have applied a discount for buying it all at the same time.

Better sound, more power.

Better throttle response, cooler running.

Designed and manufactured by us in 304 stainless for both the headers and silencers.

45mm big bore headers, vast improvement over the cheaper and easier to manufacture 40mm pipes you will find elsewhere.

Royal Enfield’s original pipes are small bore and have a welded in cat.  This makes them very restrictive for your bike.

Our de-catted Big Bore pipes unleash a load of power.

Huge weight saving when swapping out the original system.

Full system is finished in brushed stainless.

Possible for you to polish them to a mirror finish with home polishing equipment.

No ECU mapping required.  Just fit the system and allow the ECU to auto-adjust.

Laser marked as 86 db and noise legal.

Gaskets and instructions included.

Available with stainless joint covers (at a heavy discount when buying with the system) or without (bike is pictured without) if you prefer that look.

EURO 5 – You MUST use the supplied baffles when running this system on a Euro 5 bike.  The warranty on the system will be voided if you run with no baffles.

Alexander Phillip
Canon exhaust system

The exhaust system was ordered from England on the 29th Jan and arrived in Australia on the 3rd Feb, service can not get better than that. I am 75 and managed to fit the system on my own in about 2.5 hours and that was with a stubby break. The fit was straightforward and up to TEC standards with no problems, just take the horns off to disconnect the exhaust gas temp. sender, not essential but helpful. On startup they sounded really good with the baffles fitted. Negatives. The stainless steel pipes and silencers are high quality and look good but the pipe to silencer joint cover is chromed mild steel plate and only chromed on one side leaving the other side to rust if not painted. The distortion on the plate from the tab welds shows through on the chrome side. Small thing but not right. Fortunately, the join is so good the covers can be discarded as I did. All up one of the better mods I have done to the Interceptor and highly recommended.

Fitted to my Continental GT , straight forward if you watch the video, a second pair of hands for manoeuvring is handy , sounds really nice even with the baffles in , very pleased with TEC and the big bore system

This is a top quality product. Easy to fit process. Amazing weight saving and the sound with the Baffles in is lovely and remove the Baffles that's a different level. But not to everyone's taste I'm sure. Also fitted DNA filter after a 40 minute ride ecu sorted it's self out..

Great product and service

I have so far only fitted the mufflers to original headers.
Very easy to fit and they sound great!
Has transformed the character of the bike.
Mainly in the sound and possibly a little more torque.
Makes the bike much more gratifying to ride.
Mufflers are so much lighter!
Worth it just for the weight saving.
A quality product at a fair price.
Fast shipping too.
Can’t wait to fit the headers.
