Got a 5.2 V8 with stock exaust on it. I want to do something muffler wise, but im not sure. Im pretty much broke so heres my options.
1. Glasspack
or
2. Cut muffler off and run just the cat and pipe
for #2 is that what open exaust is? and does it hurt gas mileage or the truck in anyway?
and its a single that sticks out the side. stock is gay. wish it had dual.
