I bought this one for mine. Tough to install but it's pretty stiff and smooth. Also reasonable at 44 bucks.

The MAP sensor is effectively giving you a "before and after" since before is 1atm. Of course you need a scan tool to read it.
I learned this year that Marc removes his air filter also when he runs the car in addition to removing his mufflers.
