hey guys, just a quick exhaust question. Right now im leaning towards the corsa powerpulse system for my 99 Z28, however i was also considering flowmaster, borla, magnaflow, and slp so if you guys could provide me with any feedback regarding the corsa exhaust or any of the other mentioned ones it would be greatly appreciated. The other question is for anybody with the corsa system...what kind of tips would you recommend? the 3.5 dual or the 4 single? thanks for any help

unless that car is supercharged you should not have over 2.5inch dual. and a 3.5 at the most is good for a single. i hear good stuff form borla and magnaflow. i currently have dual 2.5 inch with 2 moroso spiral flow mufflers. the sound is amazing, very deep noise, but it lets everyone know your there when you porke it. nice idle too.
