New to the forum and I must say that I've learned a good bit about my stryker from this forum. I just installed the Twin Slash Staggered from V&H and after about 50 miles of riding I noticed alot of poping or backfiring when I let of the gas. I was wondering if anyone else with this exhaust was running a little lean and used a fuel management system to fix it. I know V&H do not make a fuelpak for it yet so each one would you go with.
