got started on this. doing 2 1/2" in/out. muffler case size is 8"x14"x4". case is 11ga, baffles are 16 ga. went heavy on the case as it will undoubtedly come into contact with rocks and other offroad hindrances.

here is a few possibly baffle setups i am thinking of.

1.


2.


3.

I'm kind of liking the first one.. that splits the flow and forces it into the 2 side baffles. However, I have no idea how that would affect actual exhaust gas flow.. nor soundwaves.

Here's where a CNC Plasma Table would be nice. It would allow you to make those 1/2 tube shapes, and position/cut them precisely where you want them in the top/bottom of the case.. so you could plug weld them.

I'm really looking forward to seeing/hearing the final product

the first one is what i originally had in mind before ever starting this project. the other 2 were just thinking physically since i had the parts in hand to see what other possibilities i could come up with.

And i am slowly but surely collecting parts for one. it is next on the big things to buy list. buying the plasma in the next couple months, already have a computer with up to date copies of Mach 3 and mastercam. it would certainly be much easier that way.

Nice idea. Just thinking out load here but couldn't you tack the shell of the muffler together with the baffles, then install it to hear it. If you don't like the sound cut the tacks and move around the baffles till you get the sound you wanted.

that is an option but it may not get a true sound unless the case is pretty well sealed and almost fully welded.. I do know i am going to install it with clamps before i weld it just to be sure it is what i want.

The first design looks the best to me. Looks a lot like the Imco one chambers before Cherry Bomb bought them

Thanks.


sadly it will probably be 2 weeks or so before i can hear them. Headers will be built next week, then it will probably be another week before i can get my hands on the exhaust bender to bend up the rest of the exhaust.

This is pretty neat. I didn't have any good advice to add but interested in the idea for sure. I'd like to see how it sounds!

I have a feeling they're gonna be freakin' loud. But if that's the goal, then perfect. The link I posted on the first page said his sounded like a deeper Flowmaster and flowed just as well on a flowmeter.

I've been kind of wanting to build a Hot Rod sometime down the road.. maybe a rat rod of somesort. I will definately do my own mufflers now.. They can be loud.. as long as they eliminate the "cackle".
