I haven't run the Toomey I got yet, But I will say that it is built much better than my Power pros right bend, I love the PP right pipe, but quality isn't as good. The silencer for the PP is ok , just the head pipe, I have had to repair a weld already, and the flange was a nightmare to seal, but was able to get it right with alot of swearing, beer, grinder and of course cometic exhaust gasket (the best IMO) better than the stupid stock round gasket, I've had no luck with! The toomey uses an oring to seal the pipe to the flange, which is soooo much better than having gobs of RTV all over. I have a ported cylinder with triple exhaust that is going to feed the toomey, if i don't like the powa, then I'll swap my son for the Power pros! He also has a Ported cylinder no tripples!
