full Greg D./LaBree system. I have no cats (pre or test) and I also have the split down pipes with a single-pop intake. I had a hard time handling the sound inside the cabin let alone outside. 2000 to 2500 rpm was the worst and I noticed that I spent a lot of time there when driving the streets when shifting, not sure how your auto will do. I didn't like the unwarranted attention from law enforcement either. I had the '92 Charcoal Grey Z at the Z show this past weekend, not sure if you heard it but if you want to hear it again, we can arrange lunch this week. The unresonated sounds good but I prefer the resonated as long as you don't have cats. Good luck! -Robert
