Re: Muffler and Cat questions
Laws in the east may not be the same as the west -- but --
Mufflers have to be used behind catalytic converters on Federal Lands (Federal law,) out west on state lands too (state laws.)
That means BLM and Forestry lands.
The muffler has to be the baffled type, not a straight through like a glass pak.
It's a $500 fine to be caught without it. The ranger tests them by running a broom handle or stick through the muffler. If bends are in the way and he suspects it's a straight through type, (and he's a pri--,) he writes you the ticket - it's up to you to prove to the court otherwise.
Not my rules, told to me by a ranger 2 hours after I had glass-paks installed! Fortunately it was still on the trailer.
Reason is sparks fly out the cat. Baffles catch them.
But -- since you barely got it running correctly now, your exhaust must be full of crap -- the smell.
Drive it a couple hundred miles, get it running properly, then smell it.
