Want a new growl and increased fuel mileage? Want improved flow, reduced exhaust temperatures, and more horsepower and torque? Want dual pipes or a sporty tip? Have a rusty system? A trail-mangled pretzel? Smog nazis on your back? There's something for everyone, with upgrades aplenty for whatever you're craving and no matter what your wallet allows, from header to tip.
