Putting true duels on my 94z has pretty much full bolt ons. Question is what size pipe should I go with car is stock height. Pacesetter headers dumping at rear end. 2.5" or 3.0"

All depends on your goals for the car. a 2.5 i believe starts to restrict at 512 flywheel horsepower. so there's your choice. my stock height has plenty of clearance with 3".

id say if your going dual you should be fine with 2.5, single should be 3

Well stock height looks like 3" is for me. Also going with e cuts and I want the biggest differance between open and closed cutout what mufflers sure I use?

On my f-body I went with a true dual over the axle system. I used 2.5'' and used bullets and cats. Plenty of sound and power. It's all about preferance, and what your plans are in the future. I did h/c/i and bolt on's, and 2.5''' is still plenty. Just my two sense.

Go true duals, then under the axle. Then, have them mount the mufflers under the gas tank. You'll never have to worry about clearance again. That's what I did with some knock-off single chambers, and I couldn't be happier. The video was before I had the mufflers moved back under the gas tank though. I had tons of clearance problems at stock height with them under the back seats. http://videos.streetfire.net/video/9...ust_192864.htm
