Where to buy muffler parts?

So I have a little free time lately and have come up with a few designs of some mufflers I would like to fabricate pretty much from scratch. I've searched and searched the net for a company to supply me with parts to help ease the fabrication required. So far the only site I have found is www.coneeng . Com (I think that's the address) for cone engineering. Now... while their supplies seem of excellent quality and price, they do not habe much of a selection of different styles. Plus I would like to initally build my first ten or so from aluminized to keep costs minimal since this is a total experiment with no computer programs anylizing backpressure and phase etc... its going to be trial and error with modifications of current design exhausts. So question is: anyone know where I can find quality perforated 2 1/2" & 3" tubing along with conical perforated tubing (like flowmaster hushpower) along with maybe different design muffler bodies possibly? And a place to supply high temp lasting ceramic or fiberglass material or something similar? Once I get a few good designs of aluminized which i plan to both have flowbenched and dynoed along with db readings I would fabricate fully tig welded stainless versions and make a thread of my successions and failures and full results to see what everyone thinks. I'm not looking to make a business out of this, just a free time thing and if I get some very successful setups... possibly take orders on them (however that would be a year or two off seeing as I would like to have some sort of flow program to tweak the best possible product if going public with them). I know I haven't made many posts here but please take me seriously... I have extensive knowledge in technical aspects of performance. I have built probably 75-100 vehicles for customers. Everything from your daily driven m5 to an all out 8 second impala to police replicas etc.

I sure wouldn't spend a bunch of extra bucks on aluminized steel or even, a low grade of stainless until I had a design optimized. Plain ordinary carbon steel available at any decent steel supplier in some light gauge (18 or thereabouts) will have enough strength and longevity to prove any design. It's plenty easy to weld and make changes as required. When you get to where you want to be, then a 300 series stainless would be the materials of choice though becoming more difficult to weld

scrap buy back

you don't list whee you are located. I worked a while for a company that Made oem exhaust for Harley and quite a bit of stuff ended up in the recycle bins. The scrap dealer would let you buy stuff By the pound. I wish I had bought more 1 in DOM , 18 in long, what was left over. from 20 ft sticks

sorry but from scratch means just that. you should start out with a 4x4 sheet of 18g and go from their. if you could buy parts off the shelf to do this, exhaust co's would be gone. good luck

muffler parts

Our raw steel tube and perforated tube came from los Angles, I worked in Salinas Ca. but that company sold out to Tenneco and they moved to some where in the mid west near the second Harley factory. and there were some muffler factories in Lincoln, Nebraska.

Really the only part I'm favoring premade is the perforated tubing and in different varieties and sized holes and patterns. All the rest I plan on making purely my own.

For many decades, I have relied on Thomas Register to find such items. It is the bible of U.S. manufacturers. Looks like they have assumed the name ThomasNet lately. Take a look at some of these companies that are under the perforated steel tubing section.......

Thanks techinspector. That's exactly the kind of resource I needed! Don't anyone worry I will keep this forum well updated on my progression and results. I feel this is a corner of the market that could use expansion on fitment and design. Yes there are tried and true mufflers and components but everything can be improved.
