How do you think this will sound?

The line that's 2/3 in from the left is a wall/baffle that is solid with the exception of the tube that runs through it from the tee which used to be the exhaust valve.

The only material added would be some tubing 5" or so on the entry and exit tubes. And the wall and support for jack points I suppose, seeing as how my buddy and I destroyed the ones inside it. The schematic here is copywrited by the way.

should sound good

 

[lifestar]

build it, film it, and i will tell you! should be pretty sweet tho.

 

[victormonopoly]

10-4. I'll keep ya posted.

Where do the exhaust gases go when they exit into the RH chamber from the short arm of the T? Looks as if they're trapped in there since the 2/3 wall is solid or am I missing something.

I had the same thought.

 

[victormonopoly]

Yeah, they're trapped. It's not actually at a 2/3 or 1/3 mark, that's just where it is in my drawing. It'll be a bit closer to the end. My idea is for it to be a little bit of a pulse arrester. I'm gonna have it all buttoned up tonight. I'm turning the other end of the casing into a slip fitting at first so I can get back in for changes if needed. Such as, a possible hole in said wall.

If gases flow like fluid, than once the RH chamber is "full", wouldn't it be the same as having a straight pipe with no T.

Blub blub blubbety blub blub blubbety blub blub at idle.

Blublblblblblblbl... blublblblblbblblbl... blublblblblblblb... through third gear.

Just a guess... I am no engineer... but I did stay in a Holiday Inn Express last night.

Build it, find out and post up a vid!!!!!

lol, ^that.

LMFAO !!!!!

With the exception of gases having more of the ability to expand and contract vs liquid, yeah. The little bit of the stock packing is still in there at the end in the chamber in question. Which probably isn't much but I'm hoping it will add to my arrester theory. Kind of like a water-hammer arrestor I guess. We'll see.

Ha ha. I'll document it for sure. I'm just experimenting with an extra can I picked up from a tiny auction site called eBay. There's a good chance I'll think of a new design later, and again later, until I get the sound I'm looking for.

I opened mine and cut out all the tube in the middle section. Should be similar to what you're planning on doing. Sounded ok, didnt' do anything for power.

 

[victormonopoly]

Okie doki,

It's a thumper, I like the sound. The video doesn't do it justice. I'll have to do a reshoot.

To be honest, it seemed to have killed some of the power. Still an experiment.

 

[thejackal]

The key is to keep the exhaust gas velocity up, so areas where it goes from a pipe to a chamber are bad. That is the reason why the race pipe makes more power than the stock muffler with the valve open. Even with roughly the same pipe length, the stock pipe open into the front chamber, where the race pipe keeps it flowing.

If you want power, you should put one diagonal pipe in the center section from the inlet pipe to the outlet pipe. Perforate it and wrap it with exhaust packing. That will keep the gases flowing, and muffler it a bit.

 

[victormonopoly]

Right. It didn't hurt performance enough for me to worry a whole deal about it. At this point I'm going for something louder without sounding like another Harley Davidson.

 

[theoctopus]

Tune it and I'll bet you get some of that power back!

I'm gonna, but I can't get my cable for my palm to work. When my K&N arrives, I'll at least flash the race map to it with my PC.
