Another Exhaust Thread :)

[vex]

I had another thought on my commute this morning (I know it's dangerous). I have functional perforated tube mufflers that are still functional. What if instead of using regular old tubing to go from the y-pipe portion of the muffler I use these rather 'small' mufflers instead. I see the benefit two fold:
1) I save money by not buying additional stainless steel tube
2) I get a quieter note because they have muffeling capability

Basically I'm doing what Ted suggested about ferrari and making a huge muffler .

In addition to this though what if I combined a diffuser and a muffler together? Have a large perferated tube design feed into a rather flat but large muffler filled with stainless steel wool and outputs into two exhaust mufflers on the side in the normal location.

Thoughts? (I want to see if anyone can spot the issue with the latter idea )

This is exactly what we're going to do with our 20B project...

Magnaflow center 4" in, dual 3" out
...into...
twin 3" in / 3" out offset mufflers in the back

It should to pretty good noise suppression.

Will you have to worry about the gas tank in the stock location? AKA if you're running hot you'll heat the gas in the stock location and if there's an accident...?

Dunno, but good question...

The owner of the car is doing all the fab'ing on that exhaust.
He's the certified weldor.

The layout sorta mimics the Racing Beat / RS*R FC turbo exhaust, with the exception of the center muffler.
We're hoping that center muffler will help quiet things down.

We were running a 4" in / out center muffler, but it was still too loud.
We've gotten warnings here in Hawaii for exhaust noise - kinda rare, so it's pretty loud.
