Nick’s Triumph America Bobber Project

November 3rd, 2010 6 comments

Nick S. is in the beginning stages of transforming his Triumph America into a Bobber. Nick used the Triumph Thruxton tank with the black/gold stripe paint combination that changed the overall look and flow of his motorcycle, as well as, several British Customs Products. We have enjoyed working with him on this project and can’t wait to see the end result.  Keep the pictures coming Nick.

NEW! British Customs Triumph America & Speedmaster Cocktail Shaker Exhaust

November 3rd, 2010 No comments

_MG_6722blog

Regular Price $525.00 pre-release price $425.00 for a limited time only!

The popular Cocktail Shaker Exhaust from the 60’s and 70’s is back! British Customs has developed a slip on “Cocktail Shaker” exhaust for the Triumph America & Speedmaster. This exhaust makes the 270 degree parallel twin come alive with the sound and performance you have come to expect from British Customs.

Manufactured from 14 gauge stainless steel, it was designed as a direct replacement exhaust for the stock unit. The exhaust fastens directly to the header and is secured using a hidden mounting bracket. Proudly made in the USA, the Cocktail Shaker is available in polished or ceramic black to suit your style.

Note: Available for carbureted models only, re-jetting required!

Latest Thunderbird Sound Test

August 24th, 2009 7 comments

This is the latest sound test for the 2010 Triumph Thunderbird 1600 prototype exhaust. We decided to remove the CAT after all to increase the performance and sound of the pipe. Shown in the video is the UNFINISHED RAW version of the pipe. Custom heat shields will be included to cover the S-bend. This is not the finished product! The pipe will be available in polished stainless or ceramic black. The bike is running on a stock tune. Custom tune is coming soon.

Let us know what you think!

British Customs 2010 Thunderbird 1600 Exhaust Update

August 13th, 2009 12 comments

We just completed the sound test and have to say we are less than impressed with our working prototype. It sounded good but there was not enough sound coming from it. While exploring Triumphs design we learned that the CAT BOX is the one creating the majority of the sound dampening. The cat has a “S” bend prior to exiting and does not flow straight through. The rattle you hear during deceleration is coming from the CAT. With those facts in mind, we have decided to put the Cat Back system on hold and go directly to the development of a Race version for the Triumph Thunderbird 1600 Exhaust (Cat Box Removed). We have two sound tests to share. The first is with the straight through mega phone (no internal packing) Cat Box Installed. The second sound bite is with the exhaust completely removed (CAT BOX ONLY). Unfortunately we got a little excited and forgot to take a sound bite of the prototype exhaust with baffling (however it was not much of an improvement over stock, you can take our word for it). By removing the CAT BOX we will be eliminating the CAT Rattle. The CAT BOX is also a restriction point, it flows surprisingly well, but leaves room for improvement. With all that said, we are re-designing the exhaust to eliminate the cat and will be developing custom heat shields. Since we are re-designing we feel it is a good time to ask you if you like our existing up swept design or if you would prefer a more straight flat pipe similar to a the aftermarket Harley Davidson Pipes? We are expecting to get crucified for the Harley Davidson comment but we have to ask. We are planning on maintaining the dual pipe look for the race version.

Tune for the Power Commander V (2010 Triumph Thunderbird 1600)

August 13th, 2009 3 comments

Thatch on Triumph Rat brought up a few valid points that we feel should be addressed.

1) Will the Triumph TOR tune work with our pipes.  Our hunch is that the TOR tune will be a little on the lean side; historically our pipes flow better than the Triumph TOR on other models. The Shorty Tune may be an alternative, but we are not going to rely on triumph’s supplied tunes. We will be developing a custom map for the British Customs Thunderbird 1600 exhaust.

2) How will the tune be updated to the Triumph Thunderbird 1600? Previously we developed our custom tunes using a Power Commander; Tuneboy made it so that Power Command tunes could be converted to work with their program. With the development of the Power Commander V I am sure Tuneboy is working around the clock to make sure they can covert the Power Commander V Tunes as well.

3)  Will the Cat Box Elimination Kit work with the British Customs Slip-On exhaust?  No, during sound testing we made some very interesting observations.  We will be following up by posting a video and explanation very soon.  Please stay tuned.

Update: The Power Commander V is being developed as we speak and, hopefully, in the next 30-60 days the Power Commander V will be released. Until then we will be unable to develop a custom tune for the Triumph Thunderbird 1600 exhaust. As soon as the Power Commander V is available we will be working with Mickey Cohen at Mickey Cohen Motorsports to develop a custom map for the Triumph Thunderbird 1600.  Mickey Cohen is one of the best tuners in Southern California and helped us develop the tune for our EFI Triumph Bonneville / Thruxton Performance Package. When we are developing our custom tune we will run a dyno run with both TOR maps along with our pipes. Only then will we know if the TOR map will work with our exhaust. We will be posting updates regarding the Triumph Thunderbird 1600 Power Commander V as it becomes available.

2010 Triumph Thunderbird 1600 Prototype Exhaust Post Response

2010 Thunderbird Prototype Exhaust

2010 Thunderbird Prototype Exhaust

Since we first posted about our prototype exhaust for the 2010 Triumph Thunderbird 1600 we have received numerous emails and post responses. Seeing as how we are still in the early stages of development we do not have all of the answers quite yet.

How much will the 2010 Triumph Thunderbird 1600 Exhaust cost?

We are still early in development and do not have a complete Triumph Thunderbird 1600 Exhaust finished yet, however, we are targeting around $500-$600 retail. Once we complete our prototype we will post the actual price.

What kind of custom tune will the 2010 Triumph Thunderbird 1600 Exhaust use?

We are planning on taking the same route for the 2010 Triumph Thunderbird 1600 Exhaust as we did for the EFI Triumph Bonneville Performance Package. Once the exhaust is complete, we will install a Power Commander III or V on the bike and create a custom tune. We will also be running a one pull dyno test on the Triumph tunes to see how they measure up to our custom tune and of course we will be taking a baseline stock tune as well. We will post our custom tune for the Thunderbird 1600 Exhaust on our website once it is completed.

Full Race Version 2010 Triumph Thunderbird Exhaust, CAT Back Performance?

We can not comment on how much performance will be gained when the CAT box is removed from the exhaust. When we start development of our race system for the 2010 Thunderbird 1600 we will quickly find out how much the CAT box restricts air flow. All race systems on the market remove the CAT for two reasons: Performance and Weight. We will keep you informed of our progress when we begin development of the 2010 Triumph Thunderbird 1600 Race System.

We will be posting a sound bite of the Thunderbird 1600 exhaust very soon.

We encourage you to comment and give us any suggestions you may have on our 2010 Triumph Thunderbird 1600 Prototype Exhaust. Please add suggestions for any other products you would like to see developed for the Thunderbird 1600. We are currently working developing on a license plate relocation kit for the Thunderbird 1600.

If you have any questions or suggestions please email us.

2010 Thunderbird Prototype Exhaust

2010 Thunderbird Prototype Exhaust by British Customs (Full Bike View)

Tucks in nice and close to the swing arm

Tucks in nice and close to the swing arm

Triumph Motorcycles Genuine Accessories offer two stock replacement performance exhausts for the Thunderbird 1600; a freer flowing stock replacement and a shorty exhaust that eliminated the catalytic converter.  The factory exhaust is quite heavy and leaves a lot of room for improvement. Fortunately, we were able to secure a 2010 Triumph Thunderbird 1600 and have started development on a slip-on cat back performance exhaust.

We had two major concerns to address.  First, performance, why have a 1600cc twin and keep it plugged up? It would be a complete waste.  Second, the appearance, the length of the 2010 Thunderbird stock exhaust is too long and flares out from the swing arm.

Our new design tucks the silencers in as close as possible to the thunderbirds’ swing arm.

Our new design tucks the silencers in as close as possible to the thunderbirds’ swing arm and shortened the overall length of the exhaust; it now ends ¼” after the axle adjuster.

The exhaust ends about 1/4"  after the swing arm adjusters.

The exhaust ends about 1/4" after the swing arm adjusters.

We are utilizing the stock heat shields and are planning on using a modified version of our America and Speedmaster Bomber Exhaust baffle.  The finished product will be offered in a polished stainless and black ceramic finish. As we make further progress on the Thunderbird street exhaust we will be updating the blog with more information. Sound test should be complete in one to two weeks. Once the Street version is completed we will began design of a race version that will eliminate the CAT box. We are still debating the design of the race version (cat box removed). Do we keep with the dual exhaust factory design or develop a left exit 2-1 exhaust? Please post comments, as we will be watching the blogs to measure response to see which direction we should take the race version of our 2010 Thunderbird Exhaust.
