Advanced Engineering Tech - muffler design??

i was throwing around the idea of making my own mufflers. not for the camaro, but for my K5. im not concerned about flow, but i got some metal laying around and been itching to do some welding, so i thought id give it a shot. whats the worst that can happen right?
anyways heres my idea.

what gave you this idea, I mean for that internal design?

im not sure honestly. i was riding in the car and my girlfirend wouldnt shut up, so i thought of things to keep my mind off of her and this is what i came up with. lol

i just went sorta how the flowmaster mufflers are designed, but gave it a semetrical design. idk honestly.

Yeah it's similar to the flowmasters...I'd leave the baffles at each corner out....and make it a straight in straight out design...instead of having the inlet/outlet offset..

as soon as i get my garage cleaned up from my latest project ill get started on it and take pictures.

Im very interested in seeing the end product, ive been wanting to do the same thing and experiment with all different designs and stuff. Do a search, theres Lots of fancy talk you can learn about it. sounds waves bouncing one way and canceling each other out on the rebound etc.

THere is a much simpler solution to all this, and something lotus have tried. :)

Simple make a sound recording of you car as it gose through the rev range with open exhausts. then invert the sound wave and play it back at the same volume as the exhaust. The sound saves cancell eachother out totaly and you have a car that has no exhasust but goes like STINK! :)

Lotus acutally made a very boring toyota, i think, sound like a V8. and it worked! :)

Yeah, but it stuck at Wide Open Throttle and crashed. Nobody heard it coming either. Bystanders thought it was a runaway Prius.

haha....... :)

still processing....(trying to acquire welder)....any more ideas/designs?

muscle car show made their own muffler,look it up on power block on spike channel.

what episode? looking for certian things on spike's website is like hunting a good woman....

i will have to go whit no off set also with out any way off knowing how the gas will act inside muffler its more or less a shot in the dark of what you are getting and if you are going to put the time into it why not make it right or not hard to chang in this why the more you play with it you can start to see what happens with each different set up

has this project been started? Also, what sound are you going for? Any off the shelf muffler being a go after model for sound?

kinda going for flowmaster sound, but nothing in particular. just want something to do.

also, i havent started it yet. the welder i had went back to its owner, and i got a bunch of other shit to do recently. so sometime ill get to it.

Years ago Me and my buddies got the idea to make a muffler kinda like that. Dident have as many baffles but it worked ok and sound like a flowmaster.

Is it a muffler to keep her quiet ? lol

Not quite large enough. Would create too much backpressure and she would explode...

I've spent quite a bunch of time thinking of muffler designs as well. The bottom line is it's gonna cost you more to make it than to buy a mass produced muffler. The exception is if the masses do not make a muffler that fits your needs.

The designs by Flowmaster are all computer designed. You have to get the spacing and size of the baffles just right in order to cancel out noise. So that style is way too complicated for me to work with.

I think the Magnaflow style is much easier to design. Like below.

I was looking at custom inlet and outlet angles at first. I ditched that idea. Now I'd like to make some really thin mufflers, about 2.25" thick. Spintech makes some, but are $140 each. I was thinking of buying some Magnaflows for half that price and then slice them open, move the material around, flatten it down to 2.25" and then weld it back up.

I basically would mount them right under the floor. Headers to muffler to dump. Another thought is to mount them behind each front wheel and have them exit right in front of the door. Mercedes SLR style. :eek2:

If you need internal pics of just about any muffler out there, just let me know. I have lots.
