GUYS I TRIED OUT THE ASV TODAY & IT DID GOOD UNTILL IT STARTED HEATING & NEVER STOPPED. WHEN I CHECKED THE ENGINE THE EXHAUST PIPE HAS ROTTED OFF SO NOW BACK TO THE SHOP TO REPAIR & TRY AGIAN.
Take it to a muffler shop and have them make you a new pipe from turbo back, but remove the muffler and straight pipe it. While your at it wrap the pipe in thermal wrap (header wrap) and it will help the head in the engine compartment. I doubt the stock muffler had any back pressure but if it did you solved two problems. I have seen this on another machine and it was a cheap fix and wasn't that much louder.
Don't know how critical it is, but I would be careful going without a muffler/spark arrestor. It's not worth saving a hundred bucks only to set a customers woods on fire. We've done some government work where they actually checked that the muffler was certified.
That's a really good point because some of the state jobs I bid on they wanted to inspect the equipment.I was good to go, but some other machines were borderline with their rigging.
I would definitely air on the side of not loosing a job. But I doubt you'll get fire out of the turbo on that small a engine. By the time it gets thru the turbine I think you would be good. Plus most of the mufflers I have seen lately are straight thru for sound basically. But I would still hate to loose a bid due to that. Maybe you can find a small retrofit from summit or jeg's, it would have to be better then from ASV. I would still wrap whatever goes back.
I have actually ran a straight pipe for awhile now, it was just some flex pipe rigged not real good though. The next setup will be right, but first I have to get the bolts out of the turbo to take that piece off & then get it retro fitted.
I never have had a problem with sparks comming out.
