I was looking around in my CHP last night and I saw something. Dr. Gas Synchronizing Crossovers. I checked it out and it looks like a pretty simple setup. It's an X-pipe crossover that you can have either before or after the cats. It said that they make custom setups for what you need. I thought I might look into this. What do you guys think?

X-pipes are for cars like mustangs with dual exhuast. They are much better than h-pipes also (sound and power).

A friend of mine added an x-pipe to his 69 Mustang and said that it made a pretty decent difference. I may try it on my RS,but want to know how much of an avg increase of power would be,cuz they're not too cheap from what I understand.

Here's their website, www.drgas.com.
They say gains of 10-25 hp, and noise is reduced by 2-6 decibels. A 3"x3" complete kit (flanges, gaskets, mandrel bent inlet and outlet tubes and the crossover junction)starts at $200. It says they also make custom kits. I think once I am ready for a new exhaust I'll try this out.

Also, my car won't sound like a mustang with dual exhaust will it? They all tend to sound the same and I'd like to avoid that.
