Never did it but seen guys in my group doing them. Parts in list in pic.

Google is your friend for such. Hopefully this guy helps. I'm not proof watching. He is using that pricey kit they sell.

Im Interested aswell. I run a 25 on mine aswell. I just don’t like how dirty the air filter gets but that’s a stihl thing.

Air filter fix was also figured out by Jason. This will stop the fines getting by.

I had it in my basket when I ordered the filter but I was in the fence cuse I have other saws with modded mufflers and they are LOUD. I already have Tinnitus so I figured don’t be stupid take it out the cart haha. So I just ordered the filter.

They SS showed 10% gains if I recall right. But yes they are super loud.

Today I am happy with just DP covers for 5% and quieter.

I would have loved the one SS he has for my muffler 084's back in the day.
I used to make my own using deflector like DP covers.
Also had the pipe front cover ones but deflector ones were better performance and tuning for me. Flush cutting it was in wrong way. I let guy that made that one for me know quick.

I am real new to the 500i. Are you saying the DP cover gives more power, but not much more loud?

No not at all. Only SS for 500. SS are loud.
Added SS above so not to confuse others.

The SS is 10% on dyno. When a DP cover was compared it was 5%. Say on 44 46 66.

If you really want added power get it ported.
