Magnaflow Street Series Dual Exhaust System; Rear Exit (99-06 4.3L Silverado 1500)
Installed on an 02 silverado. Very simple to construct and install. Took around 3 hours to install including time spent to cut one of the bolts out of the old one. Sounds amazing and you can feel the difference in power. Not much was added but correct backflow makes a lot of difference!
