I have a stock muffler off of a wild thing 2375.
Is it worth modding?

What is the best way to do this?
Thanks for your time.

Is your muffler black with the two small louvers in the back ?

Yes
I came apart real easy.
4 parts
1 front piece
1 back piece
1 baffle
1 screen

If I close the two holes in the back, and cut and long slot in the front above the two bolts ( open it up to point down.
Is this a good way ,with out welding a pipe aiming to the blade, will I notice an improvement other than being louder?

Yes, you will have more performance and it will be loud. I tried a front outlet and thought it was too loud. After 6 different mods the one that performs and is not too loud is to cut a 1/4" by 1/2" opening downstream of each rear louver . This makes the total outlet area about 0.34 square inches .

Do you have a pic showing that mod?

The stock muffler came apart easily.

My understanding is to remove the baffle and screen.
I heard of closing these two holes , and opening up the side were the bar is works better.

Now I hear if you just open up these holes (to the right of each ) will work with not so much noise .
I was thinking of putting two hole in the front piece,

Right above the bolts.

Here's something to consider, two 1/8" by 1/2" outlets in the front and two more in the back .

What would happen if I enlarge the holes in the baffle?

 

[Smcgill]

Ok there is no turning back now!
I enlarged the two stock holes on the muffler's case , and cut the back of the baffle out, and made the holes larger on the front!

I'm waiting on a coil so I can con't with this fun project!
