The Magnaflow Cat-Back Exhaust System for the 2006-07 Chevrolet Monte Carlo is made entirely of stainless steel and features polished stainless steel tips and mandrel-bent piping for maximum flow and horsepower.
The sound and power gain is great, especially when afm takes over and the 5.3 goes into 4 cyl mode. Makes the engine sound like it has plenty of power in reserve (and it does!). Only gripe that I have is it is so close to rr sway bar and works its way loose. I have to re-tighten the system on occasion (twice so far).
