Does anyone have any experience with the Specialty Spares TT pipes for there Bonnies or T-100's

Going to ride my bike to Bonneville next September and make some speed runs. I think these pipes are right up my alley, plus they should reduce some weight.

Your input would be greatly appreciated, THANKS.

I love the sound and look of the TT's. I haven't noticed a change in performance,but I haven't re-jetted yet.

I have the TTs also, got about 600-700 miles on them. I love them. I haven't had them checked properly on the dyno, but I definitely feel an increase in power in the upper rpm range, say over 4500 or so, but a little loss of torque in the low end. I bet if you were to do the airbox elimination and get the jets sorted out on a dyno, you would see substantial gains..

Mine are jetted the same as for the D&Ds they replaced, I forget exactly what I was running but I think it was about 132 mains and 42 or 45 pilots, stock airbox with the snorkel removed. Champion Cycle checked the jetting for me with the TTs and said it was spot on....

Also, they sound AWESOME!!! Loud and mean, with a nice rumble at idle and a loud bark when you get on them on the highway....
