T-5's vs TR-6's

[KenC]

When asking a question like which is better. I would suggest saying: "has anyone Dyno'd a set of t5's and t6's on the same bike? What were the results?"

You will get a ton of opinions on which is better according to how someone feels or what they heard was better but facts are facts. There can also be issues with propper jetting, timing etc... where one pipe performed better because the other pipe was incorrectly jetted.

I have seen a stock motor get more rwh with the T5's and 2-1 y-boot than the same motor with t6's and 2-1 y-boot. The t6's had a slightly better bottom and mid which might be good for some. Personally I think that Toomey marketed the pipes for a stock motor because they needed a new market, not because they perform better.
