I actually like the sound of the standard exhaust on my ATAS.
The day I was at a bike event and my mate won a draw prize for an exhaust. He already had one so sold it to me for £50.
So a bit of modification to a link pipe I had and here it is.
Pretty pleased with the result. Sounds great. Slightly deeper tone than original and it has removable baffles.
All in all a quality item from Lextek all the better at half price.
