We normally would need either your complete bike, frame cradle & engine or engine cases with top end to build you a custom pipe. We also have a custom pipe jig that we designed and built, so now all we need is your stock exhaust and flange, pipe mounts and the muffler you want to use, and after filling out a spec sheet and sending everything out together, we will be able to build your pipe. We will need 3-4 weeks after receiving items from you, to perform this service. Inquire for the spec sheet and we will email you out a form.
