You gain roughly 50 whp midrange with catless vs 26-29 whp with catted downpipes.
The beauty of catted dp's is that you wont have to deal with a CEL and drivetrain malfunction caused by air/fuel ratio that's thrown off spec by having so much more airflow.
On the down side it costs twice as much so pick your poison.
As couple suggested I would start with a downpipe. The best bang for the buck, aside from BMS piggyback tune.
Exhausts dont really add that much power, but in the sound category you will definitely hear the difference.
I started with AMS catless DP, had it for 6 months and then wanted more sound. Bought a Meisterschaft exhaust with valve control and I love the sound now.
I get thumbs up every where I go because most people dont expect a luxury sedan to sound like a LS7 on crack. PM me for more info.
