which exhaust does everyone think is the best for the speed four i already have a two bros but im thinking of a scorpion or an ixil. any opinions

JohnB

Why...what's wrong with the 2bros? Or are you looking for a different sound?

briwedd

i was told by the dealer by me that the pipe may be the reason it runs weird but now i was talking to the dealer i bought it from and they say try new plugs and maybe a power commander. so i dont know what im doing

Forget the Power Commander, & the new exhaust. Order a TuneBoy, & if you can't find someone local who can help you use it the email support is supposed to be really good.

Should i spend money for a new TT exhaust system, or can i just take off the stock peashooter's. They look almost the same, and will I have to have it tuned and rejeted, for ether one?

briwebb, If you're experiancing surging, caused be a lean mixture, you'll need to have the ECU remapped. The Triumph dealer should be able to do this.

ericmeans, The majority of the time when backpressure is reduced in the exhaust system, the carb will need rejetting/needle relocation.
