exhaust

[outlaw mxer450]

has any one heard of or used the ac racing flow exhaust they are claiming that it makes 10 hp

[somewon]

I wish they had the dyno sheets for the outlaw posted on their website. all the other dyno sheets look pretty impressive, except for the 450r slip-on.

[outlaw mxer450]

im thinking about geting it but dont want to spend the money and it not work i wish i could get more info on it

[birdman7389]

10 hp? I call BS. you dont get a 20%+ gain from an exhaust pipe. MFG's can CLAIM whatever they want, and dyno sheets can be made to say lots of things also.

[bpjr07]

what they do is get a heavily modded engine and toss on the stock exhaust which will choke it up loose power....
then they toss up there exhaust and gain a lot of power

[outlaw mxer450]

well dosen't that show the exhaust work if it make that much of a diffence on a mod motor or stock it should be the same because they need a base line to go off of

The FMF power bomb and a jet kit made a huge difference on mine

[525Outlaw#55]

I also have the FMF 4.1 with the powerbomb and jetted and I could tell a good difference

[outlaw mxer450]

i see alot of guys with fmf and alot with the ct pipe which is the better of the two there about the same price ive got motor work dose that make a diffence in which is better out of the two what do u guys think

[525Outlaw#55]

Many say this and many say that, I like the FMF because it is the lightest exhaust, sounds good, makes good power, rath racing uses them as well as the factory polaris racing team, and FMF has worked with KTM for a good bit. Just what I think but I'm sure there's other who think differently, everyone has their opinion ya know

[ROB450mxr]

Both pipes are good. I actually just put the CT on my 450 and I'm very impressed w/ the power. The only thing I don't like about it is that I have the side mount version and the bracket they use for the silencer rubs on the subframe but besides that I love it.

[outlaw mxer450]

ct as both a side mount and center mount do they make the same power and fmf dosent have a dyno sheet to prove there power i think im going to go with ct from what i heard they make the most power and thats what im after

[ROB450mxr]

They make a side mount or center mount for the straight axles I don't think they make a side mount for an IRS. The side mount comes with 12 discs and the center mount comes with 14 discs because of the difference in back pressure. I hope they offer the same amount of power but I'm not possitive. They designed the side mount so u could modify the restricted airbox on the 450 and 525S.

I'm gonna put mine on my buddies dyno in a few weeks and I will post the results for u.

[outlaw mxer450]

thanks for the info the air box isnt that big of a deal for me i got the rath intake and u have to cut the back and some of the sides out of it so i dont think the center mount will hurt me but let me know what hp u get out of ur 450

Take a look at the AAEN performance pipe. I have a pipe from him. They are hand made and perform just as good. Not to mention they are considerably cheaper then the big names like FMF and others.

I just ordered my exhaust from ct racing for my 525s. I have an FMF 4.1 titanium slip on right now. Cant wait to see what it does.I will also be putting on the K&N air filter as well.
