I just bet your loving those Sampsons! I Just finished swapping out my stock pipes for a set of V&H Big Shot Staggered...Sampsons were my original choice but I got a really good deal on the V&H's and couldn't pass 'em up. I don't think anyone keeps thier stock exhaust for long...too quiet! I added a Ness Big Sucker and a PCIII along w/ the pipes and installed the works a day after I got my Standard back from the dealer's service dept. I had the 25* injector swap done (covered under warranty) and with the pipes, AC, and PCIII my '06 Standard runs and sounds GREAT!
