I've got exhaust on my car(custom). I raced a 2002 V6 Accord and we stayed dead even all the way from 0 to 100 three times in a row... I dunno what the Accord had except a custom exhaust system as well, just some guy i saw on the street and smiled at so i couldn't tell ya what else he might have had.

Don't the V6 Accords with the new body style have 240 horse stock?

Edit: I dunno if he was auto or manual
