I know this is gonna sound stupid. What is my advantage to moving from an h pipe to x pipe?

Thanks,

Scott

Nevermind. I just read the sticky about it. I think I understand it, maybe.

They say that an X will have better scavenging, and you might gain a horse or 2. To me, it's the sound that is different. X is more of an exotic sound, where as an H is a muscle car sound.

They say x goes with turbo or straight through mufflers, and h should go with chambered.

I had an x with borlas, sounded great, but i swapped out my mufflers for some chambered Edelbrocks and with the x, they sound amazing.

Thats helps alot. I guess I'm just gonna have to listen to some different exhaust to see what I want. I too am after sound and not so much performance with this particular mod. I currently run Flowmaster axle back.

If you plan keeping the flows I don't think you will like the sound they make with an X-pipe.

Man I am going so many different ways with this. I like the sound of the flowmasters, but it's not quite loud enough. I really don't plan on changing them, so I might just have to live with the sound I've got.

Other choices would be an O/R H, O/R Prochamber, H pipe with hi-flows welded in or prochamber with hi-flows welded in. Here is a little write up that I did on another site about prochamber w/ hi flows.
This midpipe set up or any midpipe with hi-flows is not talked about too much. I know up until about 2 yrs ago. Mac made a prochamber with CATCO hi-flow cats, but for some reason that set-up stopped being produced. I believe it was Blow by Blow racing that wanted to start selling prochambers with magnaflow hi-flow cats. I guess that never came to fruition.
Prochamber w/hi-flows is a little price option. $389 for the prochamber, $225 for pair of magnaflow cats, about $85-100 to have the cats welded in. That is midpipe that cost nearly $715. Best bet is to pick-up a used prochamber. I bought mine from local seller off craigslist for $250.00. The sound of an o/r prochamber like any midpipe is loud when you compare it to the stock catted H. Believe it or not at certain RPMS all o/r pipes including the prochamber can sound raspy. What did hi-flows actually do for the sound. The volume is in between the stock H and the o/r prochamber- just loud enough. Cleaned the sound up were it didn't sound as raspy and compared to the o/r prochamber it gave it a deeper tone. I also got back the back pressure that I was missing with the o/r midpipe.

Summary:
Prochamber w/hi-flows is a little expensive $710-720 parts and labor. Buy a used one if you can.
Volume is just right (of course that also depends on your axlebacks)
Any lack of back pressure will be resolved when adding hi-flows.

Get an off road H-pipe for your flows. That is the set up that I have and it sounds amazing. All of my friends down where I live that have the new mustangs want to change out their exhaust to what I have. I have had loudmouths, bassani's, etc. and nothing compares.
