Delkevic makes a header pipe, it is decent , quite good and they make a OEM replacement as wellI sold my TwoBros C5 titanium slip ons for $450. I bought a full Yoshi SS system for $650. Don't we have a thread states that the Delkevic brand is no more and doesn't really add HP?
They did, no more nowDid Two Bros. make headers at one time ?
If you want to go 4-1 header act quick sell your clip ons and buy the Yosh system, the price is fantastic for a quality system. I followed links, sent emails spent time on the phone, there are no more makers of full exhaust systems for the XX or anyone making a header pipe alone of 4-2-1 at this time. You may get real real lucky finding a discoed system on a shelf in a bike shop somewhere but most sites listing anything will reply "oh thats long gone"have a 98 blackbird with two two brothers slip ons. Looking for some info on a header supplier for this bike. Any Leads??
