Ya know, actually I'd do it like this:

Headers > Cats > XPipe > Mufflers > Resonators

That XPipe will help maintain torque and equalize the exhaust gas pulses, promoting exhaust scavenging.

It's a toss up at the moment, I'm trying to decide how important interior noise volume is going to be down the road. But yea if I had to pick one right now I'd go with Magnaflows. And have fun while your off work this week!

I know the general purpose of X/H-pipes in true duals, but what are the differences in putting an X/H-pipe before the Cats and after the Cats?

If the muffler's too loud, just turn the stereo up, lol! JK, keep us posted on what you go with, and pics of the install = extra credit, lol! And thanks, I will enjoy some time off, got a couple things to do with my truck this week, too.

The gases are too hot in front of the cat to begin to pulse or "cross over".

An old racer's trick is to take some black paint and paint the inside of the pipes downstream of the headers. They also metal score a line in the pipe where the paint begins and ends for reference.

Then they go out and get the pipes good and hot. The paint burns off the pipe, from the headers back, and where it starts to cool off (the crossover point - the gas has slowed and cooled here, the gas pulses slow down and equalize) the paint is still there. That's the spot they cut in for the crossover pipe.

An X configuration is more efficient than the old H pipe arrangement as the gases follow the gentler angle of the X vs. the hard right angle of the H.

Obviously, where the X meets in the middle of the two pipes, it's an open chamber.

Not trying to kiss here a*$, but it's information like this that makes me glad I joined these forums. Thanks MADDOG!

I'm gonna' do a little research and see about gettin' an x-pipe fitted to my system now if it's at all possible.

Quick question Moe, absent the drone, what is the noise level in the cab? Guess I'm beginning to think my truck is just too quiet, lol!

- Cajun
I loved the sound level. I thought it was great while cruising and even better at w.o.t! It wasn't too loud for me but was for my wife.
I used the Magnaflow 14568 http://www.magnaflow.com/02product/s...e=main&id=8246

If you want more noise, stick with the 2 1/2" dual in/dual out and get a smaller muffler. Magnaflow makes them too.

That's good info that Maddog posted. I think we accidently put my x-pipe muffler in the right place, that's why it worked so well.

One mistake I made was when I tried the whole system with 3". I thought that a 3" x-pipe muffler and 3" tubing would work better, it didn't.
I spent a lotta $$ figuring that out so I suggest sticking with 2 1/2" for true duals.
I also think the 3" setup we had put the x-pipe muffler too far back and made it sould like awful.
I have pics somewhere in the archives that I'll look for.

Appreciate the info Moe's. I'll be sticking with 2.5" pipe that's for sure.
