Outlaw 525 exhaust, the definitive thread
(Click here to view the original thread with full colors/images)

Posted by: ojcool

Would everyone with an aftermarket exhaust kindly post their feedback in this thread?

Since this question is asked all the time I thought I would start a thread to get all the info and feedback in one place.

I was doing my monthly search on ebay for aftermarket pipes and I noticed a couple different options I had not seen before.

If anyone has a link to vendor websites and especially dyno sheets please post that up as well.

Here is a link to an exhaust I have never seen before. It is Trinity Racing. This company has a really good reputation in Yamaha Banshee world. The Trinity T5 pipes were considered the best for the YFZ350 two cylinder two stroke. Note that this is a complete header/muffler system not just a slip-on.
Price: Retails for $529 on ebay $474

Trinity's Webpage
Click on products, polaris, outlaw 525. Click on the "demo" button. Not a bad looking piece.

Next there is the DG racing offering, or offerings I should say.
They have a total of 5 different exhausts some slip on, some complete.
Price: They range in price from $199-$559.

Last for new ones I have seen recently is the AC Racing.
Price: $430 complete exhaust

Got to say it unique looking. Pretty cool actually.

Now for the classics,
CT racing
Price: $534 complete system
CT's website

HMF
Price: $239-$359
HMF's Website

FMF
Price: $287-600+
FMF's Website

Yoshimura
Price: $374-$774 slip-on/complete system
Yoshi's Website

I know there are some other manufactures, please if you know of a different pipe post up the info on it.

I'm really interested to hear peoples experience with the DG AC and Trinity pipes. The Trinity looks pretty good to me. If the quality is the same as their old T5 pipe kit for the Banshee. But the really cheap DG 0 series pipe, I'm just curious how it performs compared to the other more expensive ones. Sound is a factor as well, I would give up a HP or two to get a pipe that sounded great.

Is it really true that there is no power in upgrading the head pipe. I have a hard time believing that improving flow there is not going to equal some HP. It looks so restrictive. I guess with two exhaust valves there is just not enough flow to create backpressure.

Posted by: marshviewripper

I would stay away from AC and DG. Theyve never been high on quality craftmanship in my opinion. The CT puts out great power but has had some serious fitment issues. Alot of guys have had to push, prod and even heat up the head pipe to get it to fit. Trinity makes good stuff as does HMF and Yoshimura. My Yoshi slip on for my 525S is a beauty. Perfect installment, good looks and power.

i just ordered my fmf powercore 4 slipon hear good things gonna give it a try and keep yall informed

Posted by: FiveTwentyFive

I got quite a hit by installing the HMF Sport and JD jetting. Quite happy.

Posted by: outlawjeff

i would not give up my ct full system for any other one out there. Gave me all the low mid and top end i will ever need, and was not hard to install at all. took about 15 - 20 minutes to remove old and put ct on.

Posted by: FiveTwentyFive

Just about every time I hear this question asked, what I hear most is the............

Wait for it......................

CT Racing!!!!

I hear it enough that I sorta wish I had it on mine.

Everyone keeps getting you and I confused. I get asked...."are you outlawjeff?" Only on photobucket though.

would also be cool if we posted witch its the loudest and quietest and bang for the buck!

I have the side mount CT pipe and I'm very satisfied with the power gain.

I like it. Good healthy increase in bottom-mid and pulls through on top. haven't ridden another Outlaw with a different pipe so I cant compare it to anything.

Like to hear anyone with the Trinity review it.

Posted by: GE4x4

I got the FMF Q4 due to series 96db limit. Even tho it's a bit louder then stock, it sounds much better.http://inlinethumb07.webshots.com/43462/2175886250065861424S600x600Q85.jpg

Posted by: markemark2k6

I've also got the CT system & I love it. It gave it so much power i couldn't believe it!!

Posted by: polfan73

I'm in the process of building my own exhaust with the stock headpipe (which I plan to have ceramic coated) and a Supertrapp universal muffler with a 2 in. core. I'm going to start with 10 discs, and go from there. I like the adjustability of the disc setup as far as powerband, and noise level. I know the CT pipe has the same setup, but I really can't spend 5 to 600 bucks on a pipe right now. I don't expect the same kind of power gains from mine as I would get from the CT, but I don't think a few horsepower is out of the question. I'll get some pics and ride results up when I finish it.

My son is a Tucker Rocky rep and I have tried a few pipes, there are none better than the CT full system. With a little jetting change my Outlaw rips with this pipe combo.

I just ordered the FMF 4.1 so I hope it will make me happy.
I'll post results when I get the new air filter on and the pipe and jets dialed in.

Posted by: ojcool

I don't know guys, I'm not saying the CT is not a good pipe but how can it make so much more power than all the other companies. I mean CT is a small outfit. For example FMF has ALOT more money and engineers to build a pipe. Same with HmF. How can CT have developed this "superpipe" that nobody else can match?

I just think there may be a little bit of hype and clique-iness going on with it.

Posted by: somewon

that's kinda like saying why didn't ford build a ferrari before ferrari.

The answer is they didn't want to spend the time and money doing the R&D. the fmf and hmf answer is to slightly modify what they are already using so the plumbing matches up, they don't design a new pipe for each quad.

just my $0.02

Posted by: sheriff525

What about a mega bomb header with a yoshi or a hmf pipe slip on? What do you think?

Posted by: yamahahaha

my buddy has a fmf power bomb header with a factory 4.1, sounds great and alot more snap to it with exhaust system for sure

Posted by: serokk

Just put on my FMF 4.1 and love the hp throughout it gives. The sound is so nice also. Deep and throaty!!

Posted by: Bombshell525

Will the 09 mxr exhausts fit an 08?

Posted by: 525Outlaw#55

Yea it'll fit

Posted by: Bombshell525

Thanks for the answer. I was looking on Motoworks site and it looks like they make a slip on and full system SR4 for the 09 outlaw.

Posted by: trex450

with two exhaust valves there is just not enough flow to create backpressure

Posted by: Lee #144

Trex are you saying that exhaust wouldn't be a good match for the 525? (talking about the motoworks)

Posted by: somewon

Trex,

Can you explain that a little more?

Posted by: dsteffen101

Will the fmf full system for an irs outlaw fit a straight axel outlaw?

Posted by: 525Outlaw#55

I don't know about that, I know the head pipe for the IRS is different than the S

Posted by: Lee #144

Has anyone tried the Yosh full system? I'm torn, I can get that Yosh full system for around 419 then I would have to get the JD Jet kit which is another 80 or so bucks. Or I can get the CT racing for 530 something plus will I still need the JD Jet kit for that as well? I know it comes with Jets but should I still go with the JD?

I had the full yoshi system first and ran it for awhile. I liked it pretty good, only reason I took it off is because I lowered mine and the rear brake piston was hitting the tail pipe and putting a good dent in it. A buddy of mine has the 09 450 and wanted a full yoshi, I wanted the full FMF so we worked out a little bargain. He still loves and runs the yoshi

Someone is trying to sound smart, but not doing a very good job at it.....

Think about what you just posted.......

Posted by: willb

Dollar for dollar. A correctly jetted machine will gain more usable seat of the pants power.

The JD kit is worth every penny. You can use every exhaust under the sun. Until the bike is jetted for the machine and "its" options, you can LOSE more performance than gained.

Now-must machines are sold "rich" as not to over wear or burn up the engine. A exhaust or air filter/lid removal sometimes feels better as it brings the air/fuel mixture closer to level.

With that some Outlaws have come lean so adding performance mods such as filter, exhaust, etc sometimes retards the performance.

CT is a great pipe and with the correct jetting it wont reach its full potential.

Dollar for dollar-I loved the HMF slip on, KN, EHS Lid, and JD combination.

I loved the CT, dont get me wrong but the sound level was a little much.

Posted by: somewon

i actually picked up a DG R.A.C.E. slip-on off of e-bay for $130. for that price I wasn't expecting a huge difference, but it was lighter and gave the quad a much better punch. I'll use it until it wears out and then probably go for a full system.

Well, I can agree with you if we are going to say that CT got lucky with the design. I doubt they have a big engineering dept to do a ton of Lab tests. I assume they have a flow bench if they build motors but not sure how useful that would be for building an exhaust. Flow isn't everything.

Because they are not the only company making a full exhaust for the bike.

Let's put it this way, you don't need the huge R&D group to figure out how to build the best tuned exhaust for a machine. The people making the most power through pipes are always the little guys. Big names like FMF, HMF, Yoshi, etc ussually don't make as much power.

BTW, Chris that Muzzy Stainless pipe is looking Very Nice!

The secret is that they tune each muffler with a certan number of disks. Some bikes use 7 disks some use 12 and some use 16 disks. CT dyno tunes each system to each model so their pipes are customized and can also be changed but the end user. If he decides he wants it quieter he can remove a few disks. If he wants more power after adding more mods he can add a few more disks. I am going with a CT full system for my 525 S. I might order the kit for the 450 MXR though because it includes 2 more disks just in case I need them.

Anybody run the Yosh slipon? How critical is the header vs just the slipon?

Posted by: bbbugn

Got the Yoshimura RS-5 today, VERY nice piece for sure, will look badass coming out from under the seat.
