Time to bust out the ipod and start going to town on the drill press....that's how most hot rod guys do it.

yeah i was thinking of paying my water jet cutting guy to cut me some sheets of 18gu stainless steel with bunch of 1/4' holes in it depending on price and then id roll it and weld it up.

Im trying to make a 3 pass muffler like the dynomax super turbo but the ends will be pie cut ends.

Hard to explain but i can draw it up if people are wondering what i mean.

Industrial metal supply has perforated sheets in all kind of thicknesses.

from the prices of these. I think im going to drill my own tubing i will try mild steel first i guess to see if my design works and how it sounds.

thanks guys ill start in the next few weeks and ill post some pics.

thats has got to be the worst plan. your going to just drill holes into a tube?

just get some perforated sheet and roll it around a tube, and tack weld the ends.

im in canada man. i just checked one of the sites its going to cost me 200us shipped for 3 tubes plus id say about 30 dollars in duty. this muffler is gonna be like 400us to build.

I wanted to go with a dynomax super turbo muffler but with the weather we have here it would probly last 2-3 years at max. Im gonna go talk to my water jet guy and see how much they would charge me to make a 12' x xx sheet of holes cut.

yeah just watched it to i find his drill holes were a tad to big. I wonder how slices like 1/8" wide by 6" would work out?? like say with a plasma cutter cut a small lines down the inner tube.

if you open your yellow pages and look for metal supply in ottawa they have a metal supermarkets with the perf sheet that you can buy. they may even have cut offs which they sell for cheaper

Hey JDMCRX

I plan on doing the same thing for my own car pretty soon. Have you decided what to use for packing? Stainless steel wool, fiberglass, ceramic? I have been researching packing for a little bit and there seems to many options.

Anyone have experience with muffler packing?

tepid1

Most off-road atv shops sell muffler packing. It's designed for dirtbikes and ****, but I don't see why it wouldn't work....

CTD-Fab

I thought about that but most bike mufflers can be pulled apart and repacked. Is there a special combo of materials that can be used to last a long time?

In my case I am doing everything out of aluminum and its not something I want to saw apart and repack every once in awhile.

Anyway, post pics when your done man

tepid1

You can make a canister with rivits, just like a bike, and go about it that way. Repacking would suck, but it's really easy.
