Thanks, its Gibson Swet Side, its the exaust designed for more low end power and quite inside the cab. For Towing and Economy really. But on average (on this truck) it only gains 8whp and only a mere 4lb/ft of torque. But even 8WHP is about a 6% increase in power. However there where reports of gains of 1-2mpg with no other modifications...my plans are a TB spacer and Intake...if i can get 22mpg out of just this ill be extremely satisfied... 22000miles to pay for itsself and it will be done in a mater of 2 years.
Anyway
Here Are Some Pics
and this is everything it got rid of.
Tiny 1 3/4" tubing with crunched bends and crappy muffler.
Needless to say im very happy with it so far.
