if i were to go with an x pipe i would go to dr gas the people that created it .stainless works xpipe is way over priced .jmho

I have the Dr. Gas unit with 3" B&B's. It's the cheapest, and they have done quite a bit of development work on it, (with Mustangs).
Painted mild steel, not the prettiest, but works good. I clocked 117mph. in the qtr. with a stock motor, Coplon duct, Watsons, Dr. Gas X pipe and 3" dumps, no mufflers.

One "problem". It is loud enough to WAKE THE DEAD !!

Bob,

Prior to this last configuration, my motor was similar to yours with the exception that I had ported the top end. My best trap speed was 118.5.
That's w the same complete (read resonator/xpipe) MF cat-back system I have on there now.

Bob,

Which Dr.Gas X did you use? The X-over Junction or the X Scream tandem?

[sammy]

the x over is your best bet. they can make it to your exact dimensions. works nicely if you want to cruize quietly with your resonator on some times . they made a complete exhaust for my black car. i use the spin tech mufflers when at the strip and can put on the factory mufflers in about 15 minutes if i want to go quiet

This was a few years ago and they only offered one model. It looks like the X Scream Tandem pictured. I told them the exact length of the resonator that I was replacing, pipe size (3"), and the distance between the pipes. They fabbed one to match those dimensions. It fit nicely.

I visited Al's Brakes Plus shop on Thursday. We took some measurements to replace the Mflow resonator. Looking at the alternatives, Al spent my money and I ordered a SW X pipe. Should be here this week.

Now that's using the old noggin,even though it had to be beat into you.

Your halfway there,now have Al order 2 mufflers for you,don't half a$$ it,let her breath.
It's like having a marathon runner breath thru a coffee stir.

Pete,

I know I'm a stubborn WOP, but Paul is making 432 at the rear using the MFLOW muffs. For the purposes of getting the dyno run done, I'm leaving them on. I'll see if the drone is something I can tune/tolerate. If not I'll go w the Dynomax muff/flapper combo. Let's see what happens with the airbridge duct and resonator removal first.

[Pete]

Then you'll be happy with 432
Yeah your right your an old stuburn WOP
