Does anyone know of a good company that makes full single exhaust systems for a 2004 or 2005 XC 600? SLP only have twin pipes or singles for ones without variable exhaust

Think HTG makes one, but i am not to sure how good it is.

The only one I've seen worth anything is the one from Carl's Cycle. They are the only ones who sell it. Designed by LRM and stamped by SLP.

My buddy did a lot of dyno work with the 600 when they first made the 600 ves motor....nothing was better than the stock system at the time under different conditions when comparing single pipe systems....said you might save a little weight going aftermarket but at the expense of more noise and harder to tune. We looked at the latest aaen single offered but found out their h.p. figures did not appear truthfull when comparing a properly setup stock sled against adding their single to it.
