Ok everyone, I have finally nailed some proper good exhausts
They are being made up for me by Phoenix exhausts in Devon, same as the shorty header pipe.
Now they have been road tested and no re jetting is needed for standard TTR, just plug and play , Keith who was testing it liked it so much, he bought it!
I have yet to test one on a modified TTR.
They are built so well, it is hard to compare them with anything else out there. They have come in at a bit more than I would have liked, but only about £50 more than a standard one, which weighs a tonne!
The new one weigh in at about 3kg, a big 1kg weight saving!
They will be in the shop very soon.
Hope you all appreciate the effort, it has been a long journey for me
