Randall: your muffler?

[RandallNeighbour]

You know, I thought of taking pictures, but it would be very, very hard to photograph those holes we're boring through a center pipe INSIDE a muffler. I couldn't see what I'd done, but the grinder tip did the "seeing" for me when it broke through and I started to make the hole bigger and bigger.

But, I'll verbally describe it for you to help out.

The muffler has two, 2 inch inlet pipes. I took an electric long-nose die grinder and put a 1.5 inch grinder wheel on it that's 1/4 inch thick, purchased from Ace Hardware.

I stuck the die grinder inside the muffler through one side opening at a time and starting grinding through the pipe that heads toward the center of the muffler, staying in one place so as to make a hole.

It took two wheels to cut a hole through the pipe... it's nice and thick.

What it cuts is a "hole" that's really about an inch long and 1/4 inch wide on the pipe inside the muffler. The snout of the die grinder is long enough to get about two or three inches inside the muffler, so what I'm planning to do is move about a half inch beyond the first hole and put in another one, letting double the amount of exhaust escape the baffles in the middle of the muffler.

How's that work for a word picture?

OK so draw on this pic. I think your putting slices in the pipe just inside the first chamber on the inlet of the muffler from your description...

Let's use the inlet on the right. If a hole or slot is cut in that pipe just inside the muffler where the arrow head is, the exhaust gases will flow through the hole then follows the path (4) out the rear. You can't see pipe (4) because it's under the others. That bypasses the entire muffler.

Ok, I think my "drill a hole inside the muffler" project was a waste of my time and a little cash. I think it sounds a bit louder, but now I'm thinking it's wishful thinking.

The reason I say this is my friend borrowed my long nose grinder and put FIVE holes in each side and it sounded no different than stock.

Sooooo, we're both gonna get a welder to put on the 1 inch bypass pipes and see if that makes for a nice loud exhaust note.

Oddly enough, I'm starting to feel a little like a ricer.
