Need non-cat muffler for Jred 2159/Husky 359

[Woodie]

I'd like to get a muffler mod done by one of the sponsors for my Jonsered 2159, and he says it works best on a non-catalytic muffler.

My dealer can't get them, and I've called Tilton and they are not available at all without the catalytic material/plate. (*&^%ing EPA!)

Does anyone here have a new or used non-catalytic muffler for sale?

TIA.

bailey's has them.

they are a sponsor here and have a link somewhere.it's about $50-$60 if i remember correctly.

I gave them a call, the only thing they have is the catalytic muffler. I've called several Husky/Jred dealers, and they all say the same thing...no way to get a new one. No longer imported by either company.

So my last hope is for either a new old part, or simply a used. Anyone?

Can't the cat just be gutted from a cat muffler?

Yes it can. I did it - do a search for 'DIY' - I posted pics in the thread I started called 'DIY muffler mod'

359 cat muffler is not the easiest to clean out, would need to be cut open and rewelded to hollow it out.

Easier to just bypass the cat part.

There is a note in the manual about the cat muffler containing cancer causing material, something to think about.

Exactly. Here's what the sponsor is telling me:

"i can port the cat muffler, it does take a little more time to drill out the cat and get all the gunk removed, but it will perform pretty good. the best performance is still the non cat muffler since it will be way way more open inside. i cant seperate the muffler because its brazed together so drilling a bunch of 1/2" holes inside then using an air micro grinder to clean them up is the only way to get at the cat."

BTW, great post, Four_Paws. I read that with keen interest first time it came out. Unfortunately, I have neither the welder nor the welding skills to do something like that on my own.

Given the difficulty in obtaining a non-cat, I'll probably just send him my cat muffler. From what it sounds like, the performance loss wouldn't be too great, and probably not worth the hassle in trying to find the part.

Thanks for everyone's help, and keep me in mind should you ever run across an older parts saw! (In the meantime, I'm still watching eBay.)

interesting.

the guy with the beard from bailey's here was telling me they had them a couple months ago.i was going to order one but i found out mine 357 already had one.try ebay for a parts saw.

Anything in a large enough quantity will kill you - eventually. Now, if you were porting 8 mufflers a day, 7 days a week, 365 days a year, for 20 years you would have a reason to be concerned. Now, look at the people with Asbestosis - mostly installers and manufacturing workers with MANY MANY years of direct exposure. I think the major risk would be from sending the material airborne - high speed abrasives, drills, etc - and then breathing it. Removing the catalytic plate likely wouldn't be an issue.

Wood_newbie - there has to be a non-cat muffler out there somewhere. Keep searching. I can't believe Husky doesn't still sell them for their non-EPA saws. I can still buy every single part for my non-EPA Shindaiwa saws. Good luck.

How do you propose to remove it without the above mentioned tools? Cut it with a torch? That can be even worse as the bad stuff is vaporized into fumes and is even more easily transfered into your system.

Is it a good idea to tell others to ignore health warnings? Let em know about the risk and let em make there own decisions.

The way TW did his 359 or rich hoffman does them you can really get out a lot of the cat out of the way. Like TW said, it didn't stop me but it did make me think about the best way to do it. Lots of ventilation will certainly help limit your exposure. Kudos for mentioning this.

The easiest way that I found it to put a port in the front and go right thru the "cat plate" the same way. In this manner the exhaust has a staright shot out!!!

Cat plate is hard as hell to drill, must be 409 or some stainless alloy.

I used a holesaw without a problem. You could always drill the outside and then use a small torch to burn a hole in the cat plate!
