Hey everyone, I am about to get a custom exhaust from Kteller's site, but would like to know if without the resonator how much louder would the exhaust be? I will be going with a ES Oval style muffler and 2.5 inch piping because my car is gonna stay NA. I would just like to know because eventually my car will become a full track car (circut), and need every bit of power to keep up with everyone else. If anyone has info or experience with this setup on their Prelude please chime in thanks.
