Hey bros. I finally joined up and decided to post after lurking around and doing some research. I have a 97 GTP sedan with 123,000 miles on it. I have already done some basic maintenance (plugs, wires, LIM, coolant elbows) Car is stock other than a DIY intake. I now have a set of SD headers that are waiting to go on the car, but i want to do the rest of the exhaust while im at it. I know there isn't much performance to be gained but i want to get a better sound. So the two systems i am considering are the ZZP 2.5 stainless steel exhaust and the SLP powerflo exhaust. Both are stainless steel, similar prices and say they can be installed easily? I noticed that the SLP doesn't have a resonator and i also can't seem to find out if it is 2.5in or what? Any advice on which system is better would be great!!
