Open headers will make your ears bleed!! I ran open headers on my truck on my way to the muffler shop and it took the rest of the day for my ears to return to 'normal'....
Hell yeah, back in the day when I had my first car a lincoln mark 7 I put a 5.0HO motor in. So my mechanic finally got the motor swapped out and left me with open headers to drive 20+ miles to the exhaust shop. ( I was too cheap to shell out 150 for a flat bed)The next morning I left 5am with open headers. DAM what a ride! First off you the sound is increadable nevermind the power increase!
My whole car was dyno-matted and the sound was still insane!
