My 2002 S has had the Borla catback on it for a year or so, and it looked great, but had a bad drone around 2000 rpms (like many aftermarket systems).
I had a weld break look on the system, so Borla sent me a free replacement. When I looked at the replacement, it has different mufflers! The original ones were 4" diameter x 16" long, and the new ones are 5" diameter. It installs the same, but have a much better sound to it. I need to drive it more, but the sound under 3K is quieter.
I am very pleased with this compared to the original. So anyone who buys the system, make sure that they send the "newer" setup.
