I'm trying to get the exhaust sounding a bit better ,I'm getting sum new headers but when it comes to size it gets a balancing act ,the smaller diameter exhaust pipes better for velocity an moving the air faster than a bigger diameter which is more for volume r but as it has 2 pipes on the inlet the noise they make isnt pulsing in harmony an they cancel the flow of the other making for a stock idle..

Do you have a big merge pipe in your current system? If you do, remove it or make the merge section much smaller.
I've never heard a bad sounding AU V8. |

A 3" single has about 12% more area than twin 2".

As I understand his engine is very mild, so a single 3" is probably better than dual 2.25".
