...and now for the counter-point....

I've had mine done ("s" hose removed, vacuum caps installed) for the past year and wouldn't go back to "stock". Love the additional rumble at start up. No change in performance, but didn't expect any. This was all about making it sound better - IMO

Without spending thousands on an aftermarket exhaust system, for me, it was a low cost (carb vacuum plugs) modification that was well worth it.
