A few notes if you are gona buy it/Install it.
I would mock up the pipes when you are installing them, Dont tighten everything just yet. Also the brackets that go from passenger pegs, you will need a nut and bolt of maybe 3.4 inch. Put the on the pipe themselves first! I had everything installed and i had to remove a few things since it is easier to bolt the bracket to the pipe first! I thought i needed exhaust gasket but the fit is seamless! You dont need it, i went to my Triumph dealer for nothing haha. Dave does provide you with the one gasket you will need, the one from the headers to the cat bypass.
Wish list. I wish the pipe collar/bracket that Dave send would include the hardware also nuts and bolts. I ended up using the old ones. Lastly same for the rear bracket that mount between the pipe and the passenger pegs. I had to go source some hardware for it too.
Overall i am Extremely satisified with the product and the fabrication and the time it took to deliver it. That extra hardware would have made an awesome product, flawless! Love it!
