High flow cats vs. catless suggestions
Hey all,
I'm running a full active autowerke exhaust with the race X pipe (catless) and rear section. It's honestly just too loud for me and I'm looking for an alternative.
Anyone have experience with the AA high flow cats added to the x pipe and rear section?
