If I were to put a straight exhaust on my rocket a 3:1 pipe. Would the 12 min tune be good enough? I really don't want to have to get into the whole tuning the bike myself thing... I don't have enough confidence in computers and me getting along. Also does anybody have a sound clip of this?
Not if he is using the Triumph tunes - which is what he will use because he has to. The dealer can install an "after market pipes" tune which will (probably) be better than stock, but it won't be right. If you can get down to Birmingham AL then PowerTripp will make everything perfect for you.
No the dealer cannot tune it for intake and exhaust modifications, using factory Triumph software. The factory tune is crap to begin with. Find a shop in your area or as close as possible that has Tuneboy and does dyno tuning. Good luck!
