imho, Supertrapp has had the edge for just about anything for at least the last thirty some years.
consider all the other options who's been around the longest with the best prices and tunability out of any other pipe. Supertrapp.
the fact that their also USFS Approved spark arrestors is only a benefit to Enduro/adventure bikes doesn't mean their just for that.
Had one on my Z1 years ago and loved it then as now, have one on my Lc4 today. next bike I get will also get a Trapp.
can't be beat by a $500-1000 pipes for around $200/250 bucks. .
