As the message says, I just bought these from predavore yesterday and don't need them. Pics can be seen from his original thread (http://67.106.88.10/Derek/exhaust.htm - 3rd pic down). The u/p has two bungs for whatever sensors you want to plug in, and I haven't measured to see if the header runners are equal length or not. I'm looking for $150 firm for both the header and u/p and this will include new gaskets. No low ballers, - this is already cheaper than ebay. I also have a separate stainless flex u/p for sale also, - no pics yet though. This one comes with new gaskets and new studs (only one bung for temp sensor). It looks to me like a GP Moto knockoff. Asking $70 firm. I can deliver to firestone but prefer not to ship. Thanks for looking.
