All right, well, I'm looking into trading my civic for a Mustang. I will be downgrading at least in my eyes on power. ((Beat my fair share of Mustangs with my civic)) But that's not the point. I'm down to try 'em. So anyways, here's the question. I look on the internet to buy an exhaust system for a 94 GT. So from here, what's the difference between long tube headers and shorty style (obviously long and short), but I mean like power, sound, flow, etc. Plus, what's the difference between X pipe and H pipe as far as those things above? Do certain ones not hook up to others? I just need to know, because I wasn't sure if shorty Mac headers to Mac pro chamber H pipe, to Mac cat back exhaust? So PLEASE fill me in! I'm curious and want to try a domestic before I go back to imports!
 
Mean part of me says = TAKE YOUR FART CAN AND GO CUT MY GRASS!
:flame:

However, you obviously found something in a mustang that you like.
So I say WELCOME !



The sound will mostly come from the Muffler. In which case you need to find out what type of sound you like better. Of course different Mufflers will give you different sounds. I think svtperformance.com has a LARGE amount of videos for you. I personally like the Flowmaster sound better then any other sound. Oh yeah, an H/X pipe either fits Long tubes or short tubes, they will not fit both because of the extra length involved with the Long tubes. Meaning, pipes for the long tubes need to be cut short so they fit the car. Don't forget about your Equal length Headers as well.

Just some things to think about.
 
LT's should give you a lot more low end torque on a properly setup combo. Just look at the MM&FF test, the long tubes had 30ft/lbs on the shorties at 3k rpms. The LT's should give you more area under the curve for both torque and horsepower. Peak numbers aren't everything...

X pipes makes more hp/tq than an h pipe. The h pipe gives you more of that loud rumble while X pipes have more of a high raspy pitch to them. Don't forget that muffs play a big roll on how your exhausts sound. The prochamber makes more hp/tq than both H/X pipes but is said to be more quite than the others.

Fitment as far as midpipes goes BBK's midpipes are some what notorious for improper alignment. It's a hit or miss with them some have issues while others have zero problems with them. All exhaust brands can be mismatched right now I'm running bbk equal length headers with a Mac h pipe and stock cat-back. On a side note it's twice as cheap to build domestic hp than import hp good luck and have fun.
 
so if you are down grading in your eyes, what was your reasoning for going with a mustang? was it better gas milage? i dont think that is why....for the power? no we arlready went over that....maybe it is the sexy look of a 94 gt?? that has to be it...
 
Well thanks for the info guys. So about the one comment about me cutting long tube headers to fit h/x pipes, why wouldn't I just buy shorty headers then? Doesn't that seem like the more logical thing to do? I'm just curious and all since well, I want to save as much money as possibly while getting decent power gains.

And yeah, I know it's expensive to make power in Imports, but it's worth it. Beating 8 cylinders with less than 1/3 of the displacement makes you feel REALLY good. But I'm done with 'em for now. At least with Honda. Now I just have to mod out a domestic, and then a Euro, and then see which is my favorite! IF you guys have any more input, let me know! Thanks!

I'm sure he didn't mean you would cut the headers. The H or X pipe needs to be shorter when installed with LT headers vs. shorties. And you can either cut the stock H pipe down, or buy a shorter H or X pipe.

Check 50Resto.com for pictures of all the options (with MAC or Basani).

BTW, if you are into spending loads of cash to beat high displacement cars with low displacement, buy a Lotus. If you want a real performance car for the real world, you are on the right track with the Mustang. And anyway, RWD trumps FWD any day for seat of the pants fun.

Let's not forget half the car as well it takes more hp to move more weight and the money you spend to beat more displacement we can do it with half the funds. I’m not bashing you in any way about you import I give props to any car that’s fast just stating a fact. As far as cutting your h pipe shory midpipes are available so there is no need to cut one. Also if you want your car to really get out of its own way look into buy gears for the rear end like 3.73s or 4.10s that will help you launch out of the hole a lot quicker and let your engine rev up into its power range a lot quicker.
 
Ahh all right. The one mustang I'm probably going to be trading my civic for already has 3.73 gears in the back. And then it has a CAI and I think just mufflers, but I want to hock the exhaust for a full set up. Then hopefully just a bigger throttle body and a new intake manifold and she'll be set until I have an abundance of cash for a used SC. But I guess thanks for the info. And to 95Cobra, I'm sorta getting the Mustang by default. My civic doesn't even run right now and the guy wants to trade me, so I just want it out of here. There's just something about having a car that runs right now that seems better than having a car that won't go anywhere right now. I just need to have a car that I can rely on to get me places.
 
H-pipes tend to make slightly more torque than X-pipes.

X-pipes tend to make considerably more horsepower than H-pipes.

X-pipe is the choice for performance alone, but the H-pipe sounds way better in my opinion.

Long tubes are the way to go as previously stated.

I've never viewed mufflers are big power gain area so I favor Flowmaster, the brand that sounds the best.
