H Pipe vs. X Pipe

[skratpiece9450]

I have a magnaflow catback on my 2004 Cobra. Which midpipe should I go with?

Tell me if I am wrong...

1. H-Pipes go with chambered mufflers.
2. H-Pipes create better low end torque.
3. X-Pipes go with straight thru mufflers.
4. X-Pipes create more horsepower at higher rpm while giving up low end torque.

Questions...

1. Which creates better gas mileage?
2. Has anyone ever compared all the different midpipes and combos of X and H pipes. I believe I read an article that performance tested all the mid pipes paired with various catbacks to determine best performance?
3. Is a Prochamber a type of H-Pipe?

I have a magnaflow catback on my 2004 Cobra. Which midpipe should I go with on this car?

Gas milage??? seriously who cares??? if you want milage you have the wrong car, id suggest a civic or moped for that, as far as which is better its gonna be a personal preference and you will get a different answer depending on who you ask, i like the X pipe because i think it sounds better, but what do i know???

The HP and TQ numbers are so negledgable I wouldnt even worry about it. A pro chamber is kinda like a H pipe just with a really big H, and they will give a couple extra horses and IMO have a super sweet mellow tone. But for X vs H its all personal choice of sound, I like H-pipes because of the deeper mellow tone. X-pipes tend to have a raspier sound.

X is more raspy. I had an X pipe on mine and didnt like it too much. Go with the Hpipe with magnaflows
