Throaty without being obnoxious, a little drone at lower RPMs - but great at highway speeds. Cool to hear the turbos whine through the exhaust, sounds "diesel-ish"

After 265,000 miles the original manifold cracked and was causing hesitation at initial take off and o2 sensor errors. These headers and the free flow catalytic converter solved both issues. I plan on purchasing an aFe cold air intake kit to complete the upgrade.
