I wouldn't be too hesitant on DanMoto. I've bought $1100 exhaust systems that didn't fit right , discolored and rotted from the inside . Even their decal was on upside down and they had the gall to send me a free plastic sticker then charged me $40 for the matching appropriate decal. This company was Zard .
For a set of pipes for $250 when normally a set of pipes for our bikes is $500+ ? I've seen the Danmotos . They're actually not that bad . Plus for the price they sell for the carbon I'd be wary . Prolly just wasn't top notch carbon .. Their titanium on the other hand are great .
A lot of guys on the 675.net have had great experiences with them .
And for their price if they rot off in 2-3 years so what . They're like the Emgos for Sportbikes . What were you expecting ? $250 Arrows ?
