I have a WR450. I'd like to remove the stock baffle insert. I understand the bike is then a bit louder. If instead I put in the Pro Moto Billet Insert the exhaust still has a spark arrestor right? I want to stay 'legal' to ride Forest Service roads and public land and I don't want to be real loud.
To answer your question... Yes, the stock exhaust can with the PMB insert is still forest legal. The sparky is definitely still in there. It willl give you a little more power and only make a little more noise. You will need to rejet (more air requires more fuel), so see the jetting guide.
However, there is a big difference with the aftermarket pipes. I have the stocker that I use for sound tests at races because it blows a nice 94. But when play riding, I use my FMF factory 4. It blows a 99db, but its got tons more power.
