Power -vs- Exhaust sound, interesting cause I will trade a couple of HP for a better exhaust sound.I really find that sentence funny. See and hear In my mind, an exhaust is all about power. More and how much and etc. Sound should be secondary, except that you do want it to be to noisy or have a drone. IOW, sound and power is a tradeoff, with power coming in first.
I can get power from other sources like Nitrous kit, Super charger or a Turbo but sound is unique and I rather enjoy a great exhaust note while I am driving.
