The stock part is apparently very restrictive and I'd like a freer flowing setup. There is one available for the Roadster that is also a cat in the muffler type.
Yeah, examining the stock part you can see how the flow is split between the two pipes causing two 180 degree turns before exiting one side. That said, I'd think the cats create more restriction than the box. But, if you want to keep the cats for their emissions properties I can see how a crossover might give a marginal gain.
I bet if you pulled the stock part off and took it to a muffler shop they could fashion a straight through replacement. Right sized pipe, a few bends and you'd be in business.

Do you have any photos of the touring with the bear claw on? Any clearance problems. You previously posted ease of install. Any problems since install? fuel mileage change not directly related to wrist twist?
Plenty of room no problem at all with the Bear Claw.
Fuel mileage dropped to 280 - 300kms ( 190 miles ) sitting on 110kph ( 70mph ). But it will depend on how rich or lean it is set when you get it dyno'd.
The torque curve showed a even increase of just below 40% right across the range so as stated I ended up with a completely different bike. The Ramair Filter seems to go well with the TOR Pipes and cat bypass assembly which all three cost me less than AU$1,000. “I’m still amazed that the set of TOR pipes were only AU$420 brand new, delivered.”
Part Number A9608090. Make sure the gaskets are supplied with them, I know some dealers separate them and charge an extra $30. Mine came from your town, Peter Stevens Adelaide, the complete kit $395 + freight. I buy from them because they are great to deal with, even though they are at the opposite end of the country.
Forgot to mention - Roadster bypass is also available on the exhaust professionals web site. The part number I provided is for TOURING tor kit NOT ROADSTER.

Yes I have the Roadster, when I went to the Triumph Australia site I realised that the TORS are different part numbers for the touring pipes, hence the price dif. Do you have a web address for the exhaust professionals site (did a google search and would take forever to find the one you are talking about)
