The exhaust system arrived quickly and was in great condition when I opened the package. I eagerly began taking off the old exhaust system, but it took forever! After several hours, some WD-40, lots of elbow grease, 2 hacksaw blades, and finally a metal cutting tool the old system was off. I then began putting on the new Magnaflow system only to find that the clamps were the wrong size! I called Magnaflow and they sent me out the right size clamps for $21.00 as I needed them overnight. I put on the first 2 clamps with no problems and they were torqued to the specified amount. The final clamp near the exhaust broke on what I assumed to be close to the torque specifications! I was very frustrated but was able to use some of the parts from the wrong size clamps on the right size clamps to get it on and tightened (of course a little less than the designated torque specifications). The exhause tip slightly touches the body/fender moulding (even after removing as much of it as I could) but it seems to be OK. After all of that, the exhaust sounds good. My wife and I only seem to notice the sound while accelerating and driving at high speeds. I have noticed an increase in horsepower and fuel economy but note that I recently added a KN air filter and upgraded to 91 octane gas as well.
