Hello you American Toyota friends,

I have a question; I want to make a race muffler my self.
But I can’t find an exploded view from it, on the internet.

Is there someone that have an exploded view from a absorbs race muffler?(free flow)

So I can see what I need.

free flow mufflers arent hard to make, take a tube equal to the size of your exhaust pipe and perforate it (drill holes), make end plates and weld them on. Then take some glass-wool/fiberglass chopped strand sheets and wrap them inside it. Then make the outer hull, by getting a pipe as big as you want and then weld the end plates to the outer hull part.

Hello, I had a free flow muffler before
But my ears can’t hold it for 10 miles, because I get deaf from the noise!!!

I want to cut open my old muffler, and rip a the stuff out of it ,and then
I want to modified (upgrade) it to a free flow with absorbs materials.
Because I like the look of my muffler, right now, but the sound is cheap.

But what I want to know is how big must be the holes in the pipe, that I must drill?
And how much holes in a inch?
And is glass-wool/fiberglass good for more than 1 year or 10.000 miles Silence ?

greats Tyn

Looks like you tig welded the tube. If thats true, tell me what you need to run a tig. I have a mig welder, but I'd like to weld stainless and its a hassle with a mig welder, so I'm thinking of getting a tig welder.

1. Tig welder
2. Shielding gas
3. Rod
4. Tungsten


Welder
----------

If your only going to weld stainless, a tig welder with DC will do.

But if your planning on welding aluminum, you need one that also does AC.

Try to get one that has a high frequency (HF) feature. It'll help with starting the arc, otherwise you have to stratch start it. You need high freq. to weld aluminum.

Some tig welders come with a air cooled tig torch and some are water cooled. The more expensive tig welders have a water cooling option.


Shielding gas
------------------

Use argon as a shielding gas for tig welding.


Rod
---------

For welding stainless you want to use a rod thats eqivilant or stronger then whatever your welding.

Example: For 304SS use 308SS rod. For 321SS use 347SS rod.

Theres other rods for mild steel, aluminum, chromoly, etc...


Tungsten
--------------

Use 2% thoriated tungsten. You can tell by the red marking on the tungsten.


Mig welding stainless
------------------------------

Its possible to weld stainless using a mig welder, but you need a high powered mig welder (runs off 220V).

A 110V unit will do it, but you need to run a small wire (.023).

Use tri-mix (helium, argon, and co2) as a shielding gas.

Yes it is tig welded. The tig machine is working on 380volt. And works from 10 Amp to 150 Amp.
But for welding the tubes i don't go higer then 25 Amp.Otherwise the stainless steel is melting.
The quality of the stainless steel is 316 ,that must be good for a muffler inside.
