In short, what is the best full exhaust performance-wise? Need it to be street legal, not concerned about sound, just power. Will I need to re-map anything? How does that go? Thanks :)

Also hopefully its not TOO expensive.:rolleyes:

thats not something that your gonna get a good answer out of. they all give off about the same power, i mean they are all in essence a straight canister.... not like the factory honey comb..

however, your gonna have to do alot of digging for dyno readings and such for exhausts, if i were u, i'd go with what sounds good, because the hp difference between them all are prob less than a half a hp off from each other. if anything.

personally I would go with the yoshi. I like the look, and the dyno readings look good.

If you want power, your obv gonna get a full system exhaust, so look for brands that offer that.

And what about mapping? What will I need for that? A power comander and a pc but will I need a dyno too? Thanks

Btw, just your opinion, do you think its worth getting a full system? Is the hp increase worth the price?

Regardless of what you get there will likely be engine maps available for your combination of performance parts that will get you a respectable tune without the expense of a dyno

Yeah i think its worth it for a full system. Why spend 400 bucks on a slip on that doesnt give anything power wise and only noise when you can spend another 150 on a full system that ACTUALLY gives you horsepower gains?

Its just a matter of how much do you want to stretch your dollar. with a full system you get more out of your dollar.

a full exhaust with a power commander or another tuner usually gives another 3-6 hp depending on what ones and how its mapped.

when your talking about a bike thats only got like 39 hp. if you increase that by say....4.. then thats a 10% increase. thats at medium hp gains. geta new air intake and filter and your get even more.

I cant remember what types of tuner systems there is out there.. power commander is one of the more common ones. theres two brothers specific juicebox.. and theres one called area p tuner. all these work very well, youd have to compare prices and stuff but all you really need is a basic one that you can upload maps onto. nothing fancy. bc your prob not gonna tune the bike yourself and adjust timing and stuff.. leave that to the pro's.



So if your looking at a full system with a tuner... pick your exhaust, and pick your tuner and order em. usually maps are free, and you can download them once u get the unit. they will match to the specific exhaust u get.

You dont need a dyno. others have made downloadable and ready maps for you already. they did the dyno runs for you lol

If it were me, and I had a lil more money I'd get a yoshi full system and a power commander, the basic model power commander. just to cut costs.
it'll be a mod I am saving up for lol

Area-P tuner, gut the cat and pick an open can. Choose pods or panel filter and enjoy.

lol yeah thats one way of doing it, if your good with a welder that is.

gatta make sure you have a spark arrestor though, those are mandatory, at least in my state.

We'll actually need to wait until all the Maunfacturers get caught up with systems for the 300 and then get some independent dyno tests across the board.
But going from history on other bikes, Akrapovic is consistantly top of the HP charts.
Keep in mind also the weight savings, as the tuners are saying every 6-7 pounds saved is equal to about 1 HP gained.

As for "street legal" that's always been a grey area, as most all the manufacturers have the " For Offroad use Only" disclaimer on the systems and slipons.

Unless you have inspection how would they know?? They are mandatory I think across the board in the USA..

My buddy took my old stock header to an exhaust shop and they gutter it for him, I think they charged him around $40 or so, his invoice just said welding service :D

I totally agree the M4 CF Full exhaust is very clean. I would never choose any other exhaust. very nice sound. next is the area-p tuner
