Now get your hole saw and cut out the inner "tube" of the muffler. If you can't do the drill 3/8" holes in the downpour and or exit where the tube meets the exit.

Now buzz off some of the top plate, re directing less gasses back to the muffler. I left a little on but the choice is yours.

Now throw it back togeather and re tune and you are set. Be sure you get your two muffler bolts and two muffler support bolts started before you run them up snug or you could have fitment issues.

Thoughts or improvements welcomed... I'd really like to spit one want gut it completely....

Oh and make sure then you throw the top cover back on you get the spark plug lead back in the correct place or it will cause the top cover to fit funny...

Watch my videos and see if its too loud... I don't feel as if it is, I believe where you remove the material from makes a large difference.

I could see how that would be loud... my other muffler is a simple one the anyone can do with just a set of bits... drilling these holes and cutting out the wierd exhaust deflector on top really lets it breathe and is not too loud. 20150627_170719.jpg

You get the muffler mod finished?! PHOTO's needed!
I haven't even started lol Put a new fuel line on my 044 for the second time in a month. The first new one had a hole or developed one rather quick. Also changed the oil in the wife's f250 and my tacoma. Hope to start on it this week. I will post photos.
