ideas and thoughts of building eather a chamberd or straight through muffler? say using a 3 inch pipe drilling it full of holes then put it inside of like a 5 or 6 inch pipe packed with sound deadning material. or building some sort of chamberd muffler? i just think it would be cool to build a muffler and if it shounds good then i will keep it on. aneybody with experience?

 

I'd rather make a chambered one, it doesnt sound as ricey. I designed my mufflers and my friend made them, they sound quite good. The first one is a straight through one, the one behind is a chambered one.

 

aney hints on how the chambers were set up?

 

Thats what it looks like, that brown part is chopped strand fiberglass around the stainless tubes and then glasswool.

 

Do a search on google for preforated tubing. I picked up some stainless 2.5" preforated tubing for a good deal.

I don't think you would want to do a chambered setup unless you want to create a restriction in the exhaust.

It will be cheaper just to buy a muffler though, unless you are trying to do something that you can't buy. Like a 3.5" in/dual 2.5" out muffler...

 

i just want to diy stuff

 

but perforated car and fab away!
