Used a Spectra 60° elbow, Spectra 3"-2.5" Adapter and a 5" section of 2.5" PVC. Not really any sound difference but undeniably better throttle response and some mid-range power. Sorry for the crap pictures gets dark too early! Oh and for the vac line I used a $6 kit from Advanced Auto with some new 7/16" hose.
