The criticism will honestly work for the better D. Just be happy with her and make sure you don't lose any pressure that's needed, it helps.

There is a "H" cross-over in the exhaust BEFORE the secondary catalysts, so the exhaust pulses are already balanced before they arrive at the resonator. The original poster didn't "mess up."

The stock resonator has an additional cross-over opening that is about 1.25' long and maybe 1/2" high. Since the resonator's primary purpose is resonance control (i.e., that droning sound between 1,700 and 2,000 rpm), my guess is that the additional crossover in the resonator is more related to sound quality than exhaust pulse tuning (again, since the "balancing" already occurred before the secondary cats).

There is no measurable performance difference between installing an X-pipe or straight pipes in replacement of the resonator; it's all about exhaust note. The X-pipe is a little more mellow, the straight pipes a little more raspy.

Best type of "Crossover" is by far channel piping IMO.

I'm surprised no one has done it yet for these cars. (At least I have yet to see it mentioned)

You'll get by far the best results and flow with a CP set up. Superior for balance and flow to an X or H crossover.

My info on this please.

Instead of an X or an H, it's just the 2 pipes side-by-side with a baffle between. I guess it's supposed to still diffuse some of the pulses but keep a high rate of exhaust flow. I dunno much beyond that. Hopefully pete does.

Yep that's pretty much it. Balances pressure, tames pulsing while allowing for maximum flow through (scavenging). Has a unique sound to it too. Most like it a lot.

Its a little more complicated to build than an X or H but time and again it proves to work best (with NA cars at least).
