If I take out the baffle/spark aresstor on my raptor 350 will i notice any change in anything?

 

The only change will be the sound. It'll be noisy, not really high-perfomance sounding, just noisy like a lawnmower. Quads these days come from the factory jetted borderline lean to pass emissions standards, so just taking that baffle out may push your jetting over the fine line and make it run too lean. It may not be so lean that it causes damage, but you could easily lose power, and will likely have an annoying pop-pop-pop when you are decelerating. I would recommend just leaving it in, and if you want more performance and a better sound, just spring for an aftermarket slip-on exhaust.

 

thanks and i got another question...If i got an aftermarket slip on would it void my warranty?

 

Under most conditions, yes. The only exception is a GYT-R slip on, because that's yamaha's own brand, and you need to have it installed and rejetted by a yamaha dealer. = big money, way more money than it's worth for the small gain you get

But for the most part, yamaha's factory warranty is pretty much a joke anyways, and they can call just about anything that happens to the quad your fault. Like if a shock blows out or gets a leak, they'll say you were jumping it, and that the owner's manual specifically says not to jump the quad because it's dangerous. Or if something in the transmission breaks, they'll say you were riding it too hard. It's so bad, that if your quad had aftermarket tires and your engine blew up, the warranty would be void because they weren't the recommended tires. It doesn't reall make much sense, that's just how it is with most dealers. If you just got the quad, i'd leave it stock at least for a few months and make sure nothing goes wrong with it, then once you're satisfied that it's a good, mechanically sound machine then throw on a slip-on and rejet it yourself.

 

ok thanks if i do get a slip on later which one should i get and will it give me a lot more torque

 

There's lots of good exhausts out there, it just depends on where you want your gains on the power curve, how loud you want it, and how much you're willing to spend. Don't expect a night and day difference though, at the most, with a rejet, you'll get maybe 3 horsepower with exhaust on an otherwise completely stock motor. 3 hp on top of 20 hp isn't the kind of difference you'll really notice, like it suddenly starts ripping your arms out of the sockets or anything like that.
