If I upgrade my GM900ST exhaust with a view to maybe chipping later and with a view to improving the breathing and getting heat away from the turbo, will the 3" downpipe ......mate with any of the existing standard exhaust parts. The reason I ask is that I have just re-newed the rear and middle boxes of the exhaust. I could take off and store at a pinch if no alternative - any thoughts?
Thanks
Mike
