force 2 system
Installed on a 2010 4.0L mustang. Pipes just make it but with some help I got it together. Sound is awesome no drone just loud enough. The hangers that come with system aren't painted. I would recommend painting then to prevent rust. I had previously installed a cold air intake system which makes the exhaust sound much nicer.
Lots Of Work
These headers are very nice looking under the hood. The install is ridiculously hard. Sound is not that much louder its more full, slight gurgling. Probably will get new mids with high flow cats also. AutoAnything seems to be the best source for general mods, much more less expensive than American Muscle for mustang parts.
