There are actually a lot of options. Beside what you mentioned there are forans, stainless ride, predators, (also from BC) and 4 or 5 more i can't recall. Just beware there get very expensive on the high side and you really get very little if anything for the extra $ in many cases. My current setup which i feel is great for the money is short TORs
(about $350 discount) and cat removal with proper tune and the power is great and the tone quite nice if a bit loud. Theres a windows app called tuneECU you can use to connect a PC to the bike and load the triumph tunes that are available. And theres a guy who had his 1700 dyno tuned using tuneECU with his cat removed and short TORs. So if you go that route you will enjoy 7.5 Ft Lbs and 5 HP@3500RPM's over the 1700 with tors and tors tune and cat intact. And you can load it yourself. So that my recommendation. For about $350 for the shorts, about $5 for a 90 degree 1.25" diameter elbow (cut in 1/2 and used as cat bypass) at a hardware store you can gain quite a bit of power. And tuneECU id free, tho you'll have to buy a cable. (about $10-20 on ebay)
Thats IMO the best way to go as far as bang for the buck. the short tors also have the benefit of allowing axl acces so you can adjust the belt or remove the wheel for changing tires w/o having to remove the right muffler. Another benefit is weight. Final benefit is somehow the short TORs reduce the bike';s vibration. I think it's the fact that the long pipes extend a foot or more past the mounting point and as they vibrate they act like a lever to transfer that vibration to the frame. whatever the reason, i'm not the only one who experienced a loss of vibration with them. They are also the least expensive pipe, and IMO the best looking. Construction quality isn't as good as some others tho it's fine, and they are 1/2 the cost of the next cheapest and about 1/5 as much as the forans !
