As mentioned they are HK 3" Long Straights. As far as I know, you can still get the Smartz 4-1/2" baffles from J & P Cycles. I added them to mine to tone it down a bit and give a little back pressure. The HK end caps only have the 1 fastener to hold them in place. The end caps are also maybe $75-$80 EA. -if- you can find them. I drilled 2 smaller bolt holes and used acorn nuts on the bolts to really secure them in place. What is your location? I found a great steal of a deal on a brand new set of HK 3" a couple years ago, and I have a set of perfectly good functional HK 3" pipes with caps, although they are somewhat blemished with nicks from backing into curbs, scratches and minor abrasions. I have them already boxed up for shipping. All I am asking is YOU pay the shipping and maybe $20 for my time and effort. Depending what part of the country it might cost you $100. Better than $800 for a brand new set if you can find them. PM me here for information.
