You would like to think the company that manufactures them would have ran them on a bike, and would know what they are talking about.
I would go with what they say, if it was me...
think I'll pass on them now, they've just hiked the price from £430 to£570 which means I'll be no cheaper than others that are available.
bastards!!!!! I liked the 2 pipes on the right as well
£140 rise in 1 go ffs!!!! and with no real support available either
they must be fekkin jokin!!!!
I really would like 2 pipes closer to the bike than standard on the right as well. and they were the best priced for it as well as having a nice looking product.
