Resonance was the reason why I replaced my resonantor. When I did the muffler elim, taking of at a stop light or accelerating on the highway was absolutely excruciating. Now, when I had the mufflers on there was no resonance, but I wanted a little more growl out of her. The piece I replaced the resonator with does a great job of reducing it to more than acceptable levels. I have a Hot Cam on order, and the LT's and cats hopefully will happen next spring. Those stock mufflers are pretty quiet, a little too quiet for me, but that's just me. But it is definitely those mufflers that are squelching your resonance.

I have a complete '94 LT1 system, sans cats, hooked up to TPIS ceramic long tube headers, which works very nicely with my blown/383/500+rwhp. I initially tried the "true duals".with "H" pipe but quickly learned the lesson of interior "resonance" nightmare............... the resonator you have does not hurt flow, quiets better than an "H" and probably an "X" and although I too would like a little more rumble; I am happy to be rid of the resonance and satisfied with the LT1s. I saw a thread where a guy installed "race bullets" resonators in front of his mufflers, with an "X" pipe and got good sound without resonance. I would recommend the you hang onto your factory resonator, add a couple dynomax super turbos, they have a 90 day satisfaction or return them.
Good luck !

Is it easy to replace the rear mufflers but keep the stock tips? are there any aftermarket mufflers that are about the same dimensions of the stock mufflers, so that I do not have to get a full catback setup?

i went to my local muffler shop and got a quote 2 flow masters 2 chamber installed with my tips 250.00

This was a very good thread for me! But I am still wondering what kind of sound I am gona get. My car is -96 LT4+ZF6, it is completely rebuild to 383 and it runs low 12s with street tires and loss of traction. I allready have pipes to convert the resonator with straight pipes, not x-pipe. The car has and will have stock mufflers in future. Car is daily driver and has single mass FW so it allready has some rattle. Have anybody converted the resonator but keeped those stock mufflers? Wondering what kind of sound that combo will make.

Go with an x pipe, you will loose back pressure, going with straight pipes will not solve the back pressure issue and you will loose performance and gas mileage, go with an x pipe
