they are nice, hand crafted with a very nice taper all the way to the cans. i had a them on my raptor and they sounded nice, but didnt make as much power as my sparks x6 race core did... who knows they may be worth a try on a big valved big bore. i wonder how they cross the mid-pipe over around that rear shock? it seems if i remember correctly that was quite a headache on the raptor as it hit my air box...
...Richard called me about some RZR parts and I inquired...I am waiting on his reply for some additional pic's and dyno chart...they sound sooo good they are hard to resist..but I sure like how quite the HMF is on my 525
Looks pretty sweet. I'd like to know how many db's it puts out. I like to mod my pipe but where I ride is 93dp limit and I think they give 3dp's or so leeway. Be nice to get the flow of a wide open muffler with low db's. I've never seen how they pipe 2 mufflers like that but do they pipe it so both get about equal flow?
