What is the difference between the o/r h and x? Which one is louder? Which one do you guys recomended.

+1. x for loud high pitch. h for low bass

I did quite a bit of testing on this topic a few years ago. X pipe makes more torque lower in the power band. H pipe makes more peak torque and horsepower. The difference is not much but is noticeable below 2500 rpm. the X is quieter with a chambered muffler and does not drone as bad as a H. For a street car I recommend the X.

In my opinion it depends on your car, catback and what sound you are going for. If you go chambered do not go X unless you want all the wrong attention, if you have a 5.0 I always personally prefer the H pipe sound but its really on you. Check out some sound clips on Youtube I'm sure you will find a combo you like.

The H-pipe is designed to allow the excess pressure from one side to bleed over to the dormant, or "quiet side" of the exhaust system, resulting in low and mid-range torque gains. At higher loads and RPM however, the pressure can't bleed across the H-crossover fast enough to help peak horsepower. Some companies that use the H-pipe design attempt to overcome this by using a shorter length, thicker diameter crossover pipe.
The X-pipe usually features a conjoined crossover junction to help "synchronize" the exhaust pulses. The X-pipe concept is to split the exhaust flow in the crossover, so the pressure in both sides will be equal and pulse-free from the crossover on down, regardless of load and rpm. Volumetric efficiency (and power production) is pretty much improved at all engine loads and speeds. The downside to the X-pipe design is sound... Because of the crisscrossing of the exhaust flow, harmonic pulsations and resonance can develop on some systems at certain RPM, which usually manifests as a "drone" or "rasp".

If you wrote this out yourself hats off to you. If its a google copy and paste good job on finding the perfect definition ![[patriot]](graemlins/patriot.gif)
