I pulled the stock baffle out and replaced it with chore boy steel mesh.

Baffle Mod

I will run the engine today or tomorrow at the latest and post my results.

You can also experiment with after mufflers- use your imagination and try to make a couple different ones.

Empiricle testing is the BEST.

There's a nice TOMOS Exhaust Pipe Muffler on Ebay
(Item number: 370107411244) pretty cheep. The only problem is that its only 2 hours left on it-If I had the money I'd get it.

Yeah, I'm an Ebayoholic

I pulled the plug out of my china muffler and wrapped it in regular pink fiberglass....it really helped reducing noise and so far no noticable reduction in power. The key is to wrap it just right...not too tight because the exhaust needs to flow through it, but not too lose as it won't really deaden the sound.

Glenn, thats a nice find,I would buy that but I,m not sure it would fit at the flange,its easy enough to bend, it would be a hassle to buy it then find out it will not fit and have to ship it back.

I'm sure it would have to be modified, but it would be a good fairly cheap pipe to start with.

I use the "pink" in the silencer for my expansion chamber on my MB, really works good. Like you said just dont pack it in too tight..........
