[Flofocus]

He has a performance muffler mated to a custom 2.25 piping job. Plenty of places sell just the muffler area for custom use. Look at trubendz.com, you can order any muffler from them and do the piping yourself. Piping is piping, you just need to make sure its not a bottlebeck with your mods. You cant cut out the lunchbox on the focus and replace it with a borla muffler and expect any gains. Change in sound....sure, but minimal power gains. you need to open that piping up!

Mufflers change the sound of the car more than anything. Some will have ricey raspy tones, some will know better and go with Borla. :P :lol:

That said, you can say he has a performance exhaust system. A custom one.
