Just got a new 40 series flowmaster on my 4 clyinder XE. Its the regular 40 series with a turn down pipe to where it comes out underneath the truck towards the middle. The only other thing I have on it right now is a K&N air filter, so its pretty much stock. I figured I have to have a cool sounding exhaust to go with my new lift and tires. It sound pretty good to me. Its quiet at idle but has a nice growl on acceleration. Its all I wanted, just a little more rumble on the acceleration. It was $106 bucks installed. Here it is.
