Hey guys, I'm tired of my 2000 GT's stock sound so I'm getting a nice new exhaust setup. I decided to go with Flowmaster 40s (dual chamber) mufflers. A bunch of guys from the local Stang club have them and I just love the sound. As for the midpipe, I like the sound of an H pipe over the sound of an X pipe. I was leaning towards a Mac O/R Prochamber. That should empty out my Mustang fund so the headers will have to wait.
My questions is about the midpipe. I plan on getting shorty headers eventually but for the time being will a aftermarket midpipe line up with the stock manifolds? Also, what do you guys recommend as for an H-Pipe? I'm looking for a nice deep, clean sound. And last, if I decide to stay legal and get a catted H-pipe will there be much of a gain versus the stock midpipe?
I have the flowmaster 40's with a bbk o/r x-pipe and love the sound. If you perfer an h-pipe I'd still look at bbk. If you go legal you will still get gains because the aftermarket mid pipe will only have 2 cats vs the stock 4 and you will probbly save some low end torque. The aftermarket mid pipe will bolt up just fine with stock manifold it will likely be just ball and socket.

just recently put 40's on my mustang with an o/r mac H-pipe. I love the sound. I paid 180 for the h-pipe new. i was looking at the mac pro champer also but the cost was near 100 more so i went with the h.

Don't waste your money on shorty headers, theres not much of a gain at all over the stock manifolds. If you're going to pay money for headers, make sure they're long tube, and honestly, if you're only wanting sound, they're not worth the money + install.
Stick with your flowmaster catback (endless debates over which one is best will insue) and go with some sort of uncatted midpipe. Either a MAC o/r H, or prochaber is most likely what you want based on what you've suggested already.
Again, no shorty headers, just go with a midpipe/catback combo.
But yes, an aftermarket midpipe will fit up fine with the stock manifolds.

To be quite honest, shorty's are good for sound if that's what your looking for. I have shorty's with a catted x pipe and american thunder flowmaster cat back. I get compliments all the time how it sounds like a muscle car. Although H pipes have the reputation for better sound it causes too much air disturbance to get any real HP/TQ gains. Are you planning of changing the whole cat back or just the mufflers? If you do decide to go LT's then I'd suggest you upgrade the whole exhaust to 2 1/2", because as you buy the mid pipe it will be 2 1/2". All opinions on here though will be based off of personal preference though. Usually what sounds good to one won't to the other.

first we have 6 cats stock and even if you still kept two on there it is technically illegal because you cannot alter a stock emission system, EVEN with two cats still on there. you will prob have an easier time passing emissions, but in states like cali where they do a visual, only two cats will still fail you.
do long tubes or nothing. as for the sound look on youtube and streetfire to see what sound you like

I have Flow 40's and a Pypes catted X, i like it. Prochamber would be a good choice also. The flows really add a nice deep bellow to the car.
