just wear a facemask, a surgical one is cool. and that last comment about the exhaust, the only problem with that is that no v6 na exhaust dyno plot has ever shown a whp gain anywhere near that whereas i could post a thousand dyno's of v6 or even an i4 that show ten hp gains at the wheels with a chip...that's the difference...but i too am a fan of dyno's, don't talk about gains without one from no on, please...
