@pricobelli - an exhaust change likely gives you more sound but I doubt you will notice any incremental HP change it might give you, especially since you currently have an engine designed for best fuel economy, not high power. . Better to save the money from an exhaust change and put it towards buying your 252 HP powered vehicle. Once you have that, any of the 3rd party stage 1 tunes will be noticeable for the increased power they provide. I haven't upgraded my B9 but I did upgrade my B7 with the Revo tune and the Stage 1 power increase was very noticeable.
