Either way, Looking great! I have my M-performance lip and diffuser on order and can't wait to get them on. Post us some more pics of those too on your build thread!
Thank you!
If the exhaust valve is open, it is pretty much straight piped... If the valve is closed, it diverts the exhaust through the resonator.
