part 2: waiting to exhale.....louder and faster!

EXHAUST

now that the engine is getting more air in, we need to expel the exhaust faster(you know in w/ the good air, out w/ the bad air..), we can do this by upgrading the exhaust system. This involves upgrading to higher flowing, better sounding, louder, and sometimes better and long lasting materials.

Catbacks
To do so lets start off w/ the catback, even though its actually a flexblack(see figure 1 for stock focus conifguration) it is still reffered to as catback. This is the rear section which most ppl choose to upgrade for small power gains and sound preference

SIZE DOES MATTER
this is where wereally need to start thinking ahead at our total power goals and how much power we plan to achieve w/ our focus, and how we plan to achieve it. Somone not planning on going passed bolt ons would be perfectly fine w/ your average 2.25" exhaust. However those acheiving moderate gains through large natural aspiration projects, or forced induction, will be better off w/ 2.5" and 3" systems
