92 OEM exhaust experiment
I have an OEM catback with muffler elims on it and the OEM resonator. I have a X-pipe and want to know where the best place is to install it. Options: 1) replace the resonator with the X-pipe. 2) Keep the resonator and install the X-pipe in the same place that the LT4 exhaust have a crossover pipe.
Which option would produce the least amount of resonance and which would be best for performance? Opinions?
Thanks guys

If it helps any, I have a 94 with aftermarket cats, H pipe in place of the stock resonator and stock mufflers. I recently put on elims and the sound was insanely loud, sounded terrible, and I lost low end. Last weekend I cut out the H-pipe and put a stock resonator back in. It sounds great now and I'm glad it turned out so good. I don't have any resonance at all and the sound is sweet to my ears. I don't know if your cats are stock but this is something to consider. That resonator has a large affect on the sound and volume even though you can see through it.

Thanks for your comments. I'm leaning towards trying an X-pipe where the LT4 exhaust has a cross over pipe in the rear just before the pipes make a turn to the mufflers. So, I'll have shortie headers, oem cats, oem resonator, an X-pipe and then the elims. I'll let you know how it sounds and performs. Meanwhile, I'll keep my B&Bs on for daily driving and shows. You're right, too much time on my hands.

I'm playing around with a very similar setup. Right now I've got the mufflers cut off and am running with the with the cut up stock exhaust. It's boomy and resonates inside the cabin too much 
, but I suspect with the elims installed the pipes will extend out to the bumper and it should sound better. If that doesn't work, I have a set of stainless flow through mufflers (I got them used and don't know who they're made by) that I'll try. When I get it sounding good I'll post my experiences.

Tom, the only way to know for sure is to install it and takes it's temperature. They'll be one area that is significantly hotter than anywhere else. That will be the place to put it. I can get a digital "point and shoot" thermometer anytime I need it. That's how I did mine. Let me know and I'll get it.

I have a prototype x-pipe coming in 3" that will fit between my hi-flow cats and the B&B resonator.....so the right x-pipe would fit up there..
If you want to go extreme, then add an H-pipe where the factory LT4 h-pipe is located.
Just replacing the resonator with the x-pipe would probably be the best performance option, but also probably the loudest. In addition to flow consideration the x-pipe probably weighs 20 pounds less than the resonator...
Just my thoughts..
