Extra holes in Strikemaster muffler?

[Dragonsm]

When it comes to these strikemaster posts, I see every now and then someone posting to drill extra holes in the muffler?

I did some searching on the net and I couldn't find anything explaining why...

Anyone want to enlighten me on why I'd want to put a few extra holes in the muffler of my almost new lazer 224?

One of the best ways to increase horsepower is to increase air flow-such as punching holes in a muffler. There is a very big problem with this though, as 2 stroke engines rely heavily on backpressure for proper performance, and the same applies to 4 strokes as well. Engineers factor all of the dynamics in for proper performance. Motorheads with experience have tweaked engines for years, but often with catastrophic results. Trial and error is the key. If you have money to burn by torching a few engines, then go for it. If not, keep it stock, especially if new. There isn't a company in the world who will honor a warranty on a modified engine, no matter what the component. If you want more info, try the equipment expert information forum. Someone might be able to safely steer you in the right direction if you decide to go forward, but take it for face value

I talked to the strikemaster reps at te ice fishing show about adding an exhaust deflector as an accessery item to sent the exhaust down instead of straight out onto my nice white walls of my house. They told me they developed just what I wanted but Tecumsah would not allow it on their engine. Still would like one, i'm sure just a deflector would not increase or decrease back pressure.

I took a small piece of tin and made a deflector for my old strikemaster, keeps the black splatter off the walls, removed a couple of muffler bolts and used them to hold the deflector in place. Works great.
