So....since it was my birthday yesterday I was given some money and I am going to purchase either a pypes off road H or pypes off road X pipe. I currently have SLP LM's so I know its gonna be loud but thats ok. If its way too loud I will put my stock tips back on and most likely get flow's. I know the X gives you slightly more HP but im looking more for the tone. What do you guys think...X or H?
H or X

On our S197 cars, you wont really see much of a difference between H or X, gone are the days of simple bolt on exhuast power.
I personally prefer X but Since you have LM's, i would say go "H", it will sound deep and powerfull, X will pass much higher frequencies through the midpipe and the LM's dont color the sound much, thus making your tone thin and shrill. With an H youll have more of that old skool Muscle car sound.

I have American Racing LT's, ARH X pipe w/ high flow cats and Roush off road (Borla Stingers) mufflers. When I first installed it it was a little raspy on hard deceleration but it seems to be mellowing. Also had a pretty bad drone at 1900 rpm's but that is fading as well.
On the dyno I also pulled 9 more hp than an identical car with a Bassani setup!

Here is my take so far.
I only have had O/R H pipes so that is where I have some knowledge.
My setups and opinion.
All are these are with the pypes O/R H PIPE.
That is my take. Never tried an X pipe.
Good luck also, I had a hell of a time getting the factory H off the car.

- flowmasters................Sounded to raspy and like poo, Bad DRONE
- muffler deletes...............Holy crap loud as hell and sounded like poo, bad drone
- with 18" magnaflow resonators..............See #2
- with 18" magnaflow resonators and flowmasters................nice and deep but not to loud
- pypes m80 mid mufflers...............see #2
- Current set-up... Pypes L/T headers, magnaflow 18" resonators directly into m80 mid muffler with straight pipes over the axle...............Perfect, nice and throaty and deep, loud only when really getting on it.

an x always makes more power up top and the same down low compared to an h. i say x, they're just better for performance in my opinion and the tests prove it.
as for mufflers, don't buy flowmasters whatever you do! they are the worst flowing muffler ever! i'd rather have the stockers than flows. google muffler flow comparison and you'll see what i'm talking about.
i think you should stay catted. high flow cats represent no measurable flow restriction in the exhaust system, plus you'll continue to do your part to help save our earth a little.
so, all in all, i say go catted x and keep the lm1's. i think you'll be very pleased overall

I see you don't have an S197 so I think you need to realize what goes for your car doesn't go for ours.
With that being said X-pipe + LM's sound horrible, there is very minor differences in power for H vs. X. If your that worried about power get rid of the cats. As for flow rate, the mufflers aren't going to make a noticeable difference either, for god's sake Kenne Bell recommends keeping stock headers on a FI car, so I doubt that Flowmasters are going to kill your N/A power.
Basically chose what you think sounds better.
ok, what i said doesn't apply to any particular mustang or any particular car for that matter.
your opinion on sound is just that, an opinion. but everything else i said is proven facts.
i didn't say flows would "kill" power. i just said they aren't much better than stock cause they arent
i just can't see spending hard earned money on speed equipment that doesn't offer the best bang for the buck, thats the only thing i was trying to illustrate to the OP.
it has always shocked me that kenne bell doesn't recommend long tube headers. LT's always add power and torque no matter how you look at it

Matt,
I think the SLPs will sound great w/ the H pipe... To be honest, I have flowmaster mufflers and I love them but SLPs are really nice sounding as well
Also, your not going to notice a huge power improvement with mufflers/mid pipe either way and whether your like me and near 475 HP to the wheels or only 280 to the wheels a HP increase from a muffler or mid pipe is barely noticeable unless your talking long tubes, etc....!
Try it with the SLPs... it won't hurt anything and you can change it if u do not like it.
I'm sure you WILL
