"Straight" pipes

I have two stock resonators that I cut off and I was surprised that was all the muffling going on in there. It's design was to kill a certain frequency only that the mufflers didn't. The installation of a X-pipe will just flow better since it isn't at a 2.5" reduction like the resonator.

Hey Tony,

Are you sure you aren't looking at later resonators? My understanding was that GM opened the resonator up A LOT in the 93-95 cars, but that the 90-92 resonators were the primary bottleneck, as they closed down to about 1-5/8" diameter. I had thought that removing the resonator from an early car would make a worthwhile difference. Is that not the case?

Thanks!
