Show off your muffler mods

[SOS Ridgerider]

Can I have your SLR?

You sure can. It’s cut in half, as I needed the flange to put back into the muffler, but it’s yours if you want it.

I want go try a baffle inside my exhaust pipe after the bend in my mill. That should quiet the thing and burn off the oils if any remain. Stuffs gets hot! I can pass gasses around it also or drill holes in the thing. After install I can insulate the pipe and see if this helps more.

Next step would a KTM type can on the end but that might get messy.

Thanks

Yeah, I let the porter have free reign on the muffler mod. He knew I loved pipe outlets and have an affinity for bikes etc, so that was all him! It sounds like an RM80

I just did a 6100 muffler, so I’ll include the baffle that was in there too.

Lmao not my chain, it was my buddy's when I went to pick the saw up. It was super grabby and chattery. It actually broke 3 teeth off in one side lol

I'm a firm believer cats belong on the couch and not in saw exhausts.

Finished, welded back together. Thickest metal on a muffler I've ever messed with. Drilled 2 more ⁵/¹⁶ holes and used factory deflector to retain screen.

@Mkinslow

Next time throw all that *s-word inside away. Use the plate or plates and some tubing for spacer blocks. Way faster, better and much easier. Even square tubing is better than all that fab work. The only thing you need to weld is the ends to tack it and the can seem.

That's what I was going to do but I didn't have anything small enough on hand. It really wasn't to bad to do it this way. I'd guess it was 15 minutes to grind away the spot welds. But yes tubing was my first thought and would have been better.

All that work could be reduced to a Reds97 deflector and big hole somewhere. After the big hole... go in with a big air die-grinder or hole saw. I like grumpy old burrs.
You put a lot of hours into that muffler, nice job.

On the last 360 I did, I ground out the cat, and then I just drilled a big hole in the baffle/flange the cat was attached to. It took forever. So it basically dumped the exhaust straight out the muffler, and I didn't have to bother cutting the entire thing in half. I also removed that entire area you drilled 3 holes in to and matched it to the cover. I then cut the cover so it had two exits.

It sounds like this when it is struggling with an 80 year old seasoned red oak log:
