TOR's or Staintune silencers will keep the original looks with an improvement in sound but probally only minimal performance, as GPMAZ said a complete new system like Jardines or the Carp Brutes will make any real difference there is how ever now a new system here in Australia but I don't know if it will be in your budget they are $1800 here and you can find more info from Ponters they will probally give the best performance on a std motor because the Carp Brutes are designed for a worked motor, there is such a thing as having to much free flow in your exhaust. The system that Ponters has IS True equal lenght while Carps Brutes and jardines are not[/QUOTE
Tors don't sound that great. Staintune's sound nice but only have the 2 pipes on the right which leaves the left side of the bike looking even stranger.
