a lot mof people on other forums have mentioned about the fit of delvic pipes compared to the motad pipes,most say the motad pipes fittede better,a few years a go i had a blackbird and i first fitted a set of motad downpipes and i found the fit not very good,i had to try and bend one of the downpipes slightly (one of the centre piped,so not bent due to transport) i had that system on for a month or 2 then i bought a set of delvic pipes,i found they fitted perfectly,the only issue which is a common fault on fully faired bikes is the delvic pipes can touch the fairing lowers
