What To Look For In A Triumph Exhaust

If you are in the market for an aftermarket exhaust to install on your Triumph, you should consider the following factors; Performance, Sound, Materials, and Aesthetic. These are the factors we consider when designing our Exhaust. After reading this article you should be able to make the right decision on an Aftermarket Exhaust for your Triumph.

Performance:

  • More efficient exhaust output allows the motor to produce more power. A Free flowing but regulated system can achieve this.
  • Back Pressure is important. You want to regulate free-flowing exhaust output with a minimum of back pressure to maintain a high velocity of exhaust output.

To get the most out of a new free-flowing Exhaust you should Increase the amount of air intake. This will likely require you to re-jet or update the ecu mapping on your bike. To assist in these areas see the following guides:

Sound:

  • A modern classic should not sound "modern." The classic Triumphs of the 1960s were known as performance machines and sounded the part.
  • Consider the amount of Exhaust volume you are comfortable with. Some Exhausts are louder than others.
  • Different muffler shapes produce different sounds; a reverse cone (see Predator Pro) has a classic tone while a henkel cut system (see GP Exhaust) has a more race tone.

Materials:

  • Weight savings is important. Shaving 10lbs off the bike can likely get you +1 HP.
  • Avoid Chrome at all costs! It corrodes and rust when exposed to weather and will require re-chroming
  • Beware of exhaust made of mild steel which is not as durable as Stainless Steel and is susceptible to corrosion. Look for Stainless Steel construction.

Note: All British Customs Exhaust are TIG welded out of 100% 304 Stainless Steel. Stainless contains Chromium (not to be confused with “chrome”) which prevents staining, corrosion, and rust. Stainless is much less malleable than mild steel, making it harder to work with. Also, the price breakdown as of July 18’: $0.39/lb for Mild Steel & $1.76/lb for 304 Stainless Steel on (agmetalminer.com). Stainless is harder to work with and cost more to obtain, but it produces a much higher quality product.

Aesthetics:

  • It's ok to care about how it looks. That’s why you bought a Triumph right?
  • Pay attention to how its made. Visible welds should be a work of art. Can you see the welds? Do they look good?
  • Does the angle of the mounting position go with the lines of my bike or create a flow?

Bottom Line:

We’ve gone over the criteria that we use when designing our pipes or considering bringing a new brand of Exhaust onto our webstore. Ensuring that you get a better performing, better sounding exhaust that is made to last and look good is a priority to us. When you are spending $500+ (sometimes over $1k) you want to be certain that you are happy with the purchase. That is why British Customs offers our 30 Day Ride Guarantee. Install our pipes & ride for 30 days. If you aren’t satisfied, return them no questions asked!

Hi Nathan,

That’s in the pipeline! We love how the Billet tips look and as of now, they’re only available for the previous VIN T120’s but we’ll have them out for the newer headers and we’ll be sure to announce via newsletter/social so stay tuned!

Thanks,
Kevin

Hi Alan,

A ToR map works well with that setup but the best would be with a Power Commander – custom tune.

Thanks!
Kevin

Hi David,

Sounds like an awesome build, especially when you’re up against he other V-twins with the nice throaty sound from the X-Pipe. Can you send me some photos over to kevin@british-customs.com, would love to check it out!

Thanks,
Kevin

I have a T120 Black and would love to just remove the silencers and install the caps you guys make. Do you plan on making them for later vin # bikes?

Thanks

Hello, I have a 2011 Thunderbird 1600 catless w/BC Hogslayer slip-ons and a K&N air filter. Could you tell me what MAP I should have installed? Thanks, Alan

I own a 2018 Bobber with shortened fenders, apes, gold chain, white walls and various other mods. Quite a good looking bike, but by no means a ground up built bike. It also has the BC x-pipe with the slash cut straight pipes, one of the first sets you produced I am told by my dealer. By far, it is the sound that turns all the heads when I roll up anywhere here in Connecticut, “Harley Country.” Loud and bruity, but not V-twinish. The sound attracts people to take a closer look to see what it is, and all are impressed with the fact that it is not a Harley, something different and cool, and the fit and finish of Triumph and BC. Most are baffled that it is a modern bike with modern features. I do enjoy the attention, but it is the power and sound when I ride that I enjoy most.
