British Customs 2010 Thunderbird 1600 Exhaust Update
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.
