G'day Paul
You have 2 options as I see it. You can delete the middle resonator or fit a turbo back system. The middle resonator delete will give you a bit more noise and no performance gain. The turbo back system will give you a bit more noise and a tiny bit of performance. For the money a remap will give you the most performance gain. If more noise is the main reason to mod your car then contact the guys at Sureflo Exhausts at Ingleburn are a great bunch of guys and do exceptional work.
