Do not listen to your dealer.I have seen this question 3 times in the last 3 days..Dealers want to sell you the TORs which will be illegal every where In a few years anyway.There illegal in denver already.. Again,dont listen to your dealer...Jack
I think you are saying that I can replace the cat (it will function) and don't have to replace three side exhaust..........and I understand the sound might not be that total loadness ...again I wonder if the 12 min tune can adjust for only the cat pipes and stock exhaust...

No, the 12 minute tune will not optimize the combination of stock mufflers plus cat bypass. There is a tune (20150) which is for stock mufflers with cat box with catalyst removed which would be close - apparently it is close now that I have read the preceding post by Her3tic. Advice: get the TOR's and cat bypass. There is a stock Trumph tune and better Tuneboy ($400) tunes for it. Why worry about a legal sounding bike when there are so many noisemakers out there?
