Ok, don’t start throwing things at me lol! Hear me out.

So we all know the big names in exhaust and the ones that actually make power, but my question is, who makes a solid performing, QUIET, and most importantly, durable exhaust?

I’ve got a couple DASAs, but they have not been even remotely durable. I’ve broken several quiet cores, and I don’t even have them in all the time. The mid pipes start coming loose after not long, the billet inlet starts to oval out, and Everything starts rattling and leaking. I’ve talked to Dan about this and he never really seems to care or offer to send any replacement parts. So I end up rebuilding them, but I have one pipe now that I literally cannot remove the mid pipe from the inlet of the pipe, and believe me I have tried, and beat on it with a no-mar maul with no success. I am not thrilled with DASA and their Customer service.

I’ve got a HMF that I seem to like, but I bought it used and I’m going to rebuild it to like new to see how it actually holds up. Their customer service is decent, but I am kinda irritated that they won’t sell the parts to me to rebuild the pipe, I HAVE to send it in to them. I would much rather do it myself, but I’m kinda interested to see how good of a job they do.

I actually bought a full titanium Pro-Circuit Pipe, and as much as I hate to say it, it’s held up Well. I would normally never buy a Pro-Curcuit, but it was titanium and I got a smoking deal on it. It’s not as loud as I thought it would be, and it sounds pretty decent, but I’m still going to stick a quiet core in it. I haven’t had it real long so take my “held up well“ Comment with a grain of salt.

Lastly, Yoshimura. I love Yoshimura pipes. They are durable, they look good, fantastic customer service, great parts availability, quiet core and spark arrestor work great, they sound good, and say what you want, but I think they make good power, but I haven’t done a back-to-back with a DASA. I’ve had a few Yoshi’s over the years, and two now, one on a quad and the other I need to repack and refresh a bit. Out of all the pipes I’ve had, I would go with a Yoshimura if I had to have only one. Now the downside, you can’t buy a new Yoshimura for an 04-05.

One of my top concerns about a pipe is durability. I ride my quads a lot, and if I’m going to spend $5-600 on an exhaust, I want it to last. A big part of that is keeping them repacked, and the Yoshi does kinda suck to pack, and the DASA is definitely the easiest. I also want to keep the pipe quiet, I don’t want to listen to a pipe drone on for 4-8 hours a day, so a nice quiet core is a must for me.

So what are your thoughts on pipes? What works well for you guys? What’s been your experience with different brands? I think most of the big names are pretty close on the power for a moderately built motor, so I’m looking for feedback on other aspects of the exhaust.

Before I went dasa I had a Lone Star Racing (think moto experts made it) exhaust I picked up used from a member here. I liked it but my buddy kept egging me on to get a dasa so I did. Dasas nice but nothing special. I wont broken it yet. I like HMF the build quality is quite good imho. On my 04/05 I had a CT Pipe and honestly it was made super well, I also picked it up used in good shape. I did use a regular exhaust tip however and dump the odd silencer thing they have on them

I never used the quite cores really so cant comment there

I have had a Rossier for years. It held up awesome to probably well over 100 xc races. Idk if the same people own them or if they are made the same but I like it and makes good power. It is loud as a Dasa or HMF and every time I have ran the supertrapp end cap to quieten it down it blew off, literally, took the whole core with it one time.

Brother just had a custom Bill Built pipe done for an open kart ant is good quality and not as loud as expected. The header broke after a couple races but Bill is going to take care of it and may change his design a little since it is on a kart. But as far as quality I would rate it pretty high.

Pro Circuit's quality is top notch. Ran one for multiple years with no structural damage what so ever. Their head pipe is restritive for modified engines. I'm currently running a Monster. Awesome pipe. Great performance, quality construction. Very happy.

Nice to see you pop in man!!

Glad to hear that your Pro Circuit held up well! I’m hoping for the same, but I just gotta get a QC for it. I’ve got my Pro Circuit pipe on a pretty mildly built machine, so not too worried about any restrictions. I haven’t looked too closely at Monster, do they offer a QC for their pipes?

that’s impressive for the Rossier! I thought I heard they were bought out, but not sure, I’ll have to look into it. I’ve seenthe new style Rossier pipes and they look pretty sweet. That sucks that the Supertrapp end cap never worked well. I don’t know why making a quiet pipe is such an afterthought. Especially with quads getting such a bad rep lately, it seems like companies would focus more on a good pipe that’s halfway quiet so it doesn’t piss everybody off. I don’t even know how guys can run all day with these crazy loud pipes and not go deaf, even with a quiet core a Dasa can get pretty irritating after riding all day.

I remember the LSR pipe getting pretty good reviews, but they don’t sell that pipe anymore. I kinda like HMF more and more lately, not sure why, but like you say I think they have good build quality. A buddy of mine used to run the CT on his 400 with the Supertrapp end on it, he really liked it and it sounded nice. I just hopped on CT Racing’s site and noticed they still make a pipe for the 450 with both the disc and turn down style like you had. I am really excited by that! I would like to try that pipe, 93 dB sure would be awesome!

haha!! Oh man, I had forgotten about them! I actually built a motor for a guy that bought one of those, it was trash lol! He talked about how awesome it was but then ended up getting a Dasa, i wonder why?!?! Lol!

The ct held up well I never had any issues honestly. I’d run it again if I needed an exhaust too

I need to check in every once in awhile. Good luck with the Pro Circuit, it will treat you well. I'm not aware of a quiet core for the monster.

it does look like Monster has a quiet core that works with the spark arrestor. They say it lowers the sound by 4dB.

 

[hawk-trx]

I would agree that yoshi makes a good solid exhaust, my first one didn't make good power becaus it ran a 1.5" header all the way, but it was built well and the ones on my Z400's have been great.
My Rossier has also held up great, I would put it right there with the rest.
Some of the others I have had I didnt keep long enough to say weather or not they would last and some started to get loose they included dasa, chm, ESR, power pro, DMC

 

[hoser]

Thanks for the input Tod!

There are a couple different models from Yoshi that have the different size headers, I’ve got one that the headpipe is bigger than a DASA, and another one is a fair bit smaller, so definitely something to know if you’re going to pick one up.

I liked Rossiers in the past, but just haven’t heard anything about them under the New owners.

 

[Bullvine rider!!]

I know this is an old post, i came across it in the search bar looking for something else, and figured I’d put my .02 in. Im sure you guys know by now, but i think empire is the new rossier, ive heard good things about them.(they better be following rossier’s quality lol) I’ve always liked rossier and pro circuits had them both on my last two 450’s.
I currently have curtis sparks and its solid but loud. I do like the louder pipes (my helmet and sitting in front of the pipe muffles it so for me it doesn’t bother my ears) I’d have to say rossier, sparks, & pro circuit. In that order. I may try empire next time around, and im getting very interested in monster more & more. The sound of a loud pipe echoing thru the woods like hell fire is about to rain down on you is bada$$. But line hoser said those days are pretty much over for us now. Which is a damn shame. Cant go near a state park with anything over 96db on my side of the street. So have to adapt by getting a Quieter slip on to swap out if i go to a state park. Sorry for the long post. Thanks guys🤙

Wow you all have sound police where you live, dang. I live in one of the most regulated places in the us. I have never had a problem at any state ohv, blm or national forest land, running Monster pipes with no quiet core. The only place i have been remotely harassed was Stonyford ohv state park and it had nothing to do with sound he was concerned that my spark arrestor was not usfs compliant.
I run all monster pipes in all three of my quads now. I think their quality, sound and hp creation is top shelf.

 

[CJM]

ive had the dasa for years now and have had no issues really. i did use an exhaust pipe expander and make the mid pipe larger where they go together and it dont come off lol i still have the moto experts lonestar racing pipe kicking around. should the dasa ever break im putting it on

oh and yes the dasa is STUPID loud

There’s a trail and scramble area in MN, and we have to line up and have our dB tested before we can get our sticker and enter.

yea thats pretty much the same with some of the parks in mass. There’s a couple places where they may not be any staff onsite sometimes and you get lucky, but it’s random. Fortunately I do still have a handful of real good riding areas that are not state run. And thats where i ride without being bothered. But im sure condos will be built in those areas sooner or later 😞. When they run out! Time to migrate west or south 😆. Like riding gypsies and nomads.

One state down from you in CT, zero places to ride ATV's legally.

I'm a Yoshimura fan, when not using OEM. The Motowerks system that came with my bike was of nice build quality. Downsides are it's super loud, and it didn't have a heat shield provision. Yoshimura seems to have the best fitment and quality in my opinion. I have one on my YFZ450R and it sounds great. My friend has a Dasa on his, and it's much too loud for no real power difference. When both are at idle, his YFZ makes mine sound stock.

The places I can ride at are private property, but due to noise ordinance if the neighbors have a problem with it they can call the police. Because of that, my TRX, KFX450R and KFX400 all run stock pipes.

That sucks! Can you ride power line trails? Us massholes dont have it that bad then 😂. Never had yoshimura, heard nothing but good things. That’s another exhaust i’d go to next for sure. 4 quads? Thats a nice fleet😃.
