I will also chime in and say the Pypes system is pretty good. Not perfect, but good for the price. Although I have the 3" system, I'm sure this applies to most systems in general. First, I installed the Pypes system AS IS. Although it did fit with no problems, and could have worked the way it was for a normal Malibu, it didn't tuck up enough for mine. My car is so low that I needed the system to hug the floorboards, and with this system there was about 3" between floor and muffler. I actually cut wedges out of the pipes in a few spots and rewelded them back together, no benders here. So if you want a decent fitting system, Pypes is ok. If you want a really neat custom exhaust, all the parts are there with the Pypes system, it just needs a little tweaking to get it just right.
