New Exhaust!! :O)
Yesterday I got a call from my buddy who told me to come over to his shop, when I got there he promptly put my car on a lift and started taking my old exhaust compltely off from manifolds back, we spent the next 6 hours fabbing and welding a custom bent 2.5 inch chambered exhaust with true dual twin 18 inch resonators and 18 inch chrome slashcut straight tips on the rear where the mufflers used to be!! Are they loud??.....In a word yes. But a very low tone, almost like sidepipes till nailed and then it sounds awesome! He cut the ends off off the resonators, swedged each one, and renippled them to close the gap inside to get rid of any popping on decel and it worked like a charm! They look awesome and the car finally sounds as "sick" as it looks! The loudness I am sure is not for everyone, but there is room at the rear to add two more resonators if I want to tone it down a little in the future, my teenage daughters think it sounds cool! He is shutting his shop down soon and will be liqidating his resonators and he has a lot of them, I will post here when he does.

My system was too loud, way too loud. Headers, 2.5" pipe, 3" Flowmaster 40s, and crossover pipe. I was looking to adding resonators, changing mufflers etc. Before we did all of that, we tried an x-pipe. That worked really good. Brought the noise level way down, eliminated the resonance, and still sounds way cool.

Hope you like the sound 
Everyone at the car shows liked the sound of mine with Flowmaster 40's on it. But when I was at a stop light other cars were stopping about 50 feet behind me and one of my windows in my garage cracked because it rattled so bad.
Sounded kinda like someone doing a drum roll on a garbage can lid. Changed them after about a week, a week or so after that I got most of my hearing back

I know it is just one mans opinion, but I have always thought that by looking at them. HOWEVER, a larger X pipe where the two individual pipes stay in place instead of a direct transition through an X might work well.hmmmmmmm Thats an idea.....

If I can hack it money wise I'll be looking at some sort of X-pipe arrangement, otherwise H.

We talked about an X pipe, but he said at speed the ehaust "fights" each other in an X pipe, whereas a crossover uses a low pressure equalization type setup and does not "collide" and cause an issue. Both skavenge well, but he likes the H. But I can see where an X would quiet a pipe, but only because it is creating an increase in pressure at that collision point.
