I want to join this convo, as I have had the luxury of hearing several different setups before making my exhaust and dp decisions. I like louder than stock, but deep tone under normal conditions, and I like it to scream when I go WOT.
I have heard:
Borla with catted and uncatted CTS dp: catted sounds better, minimal drone around the 3300-3400 area.
Milltek with catted APR: Sounds dope, almost bought this,
Xforce with catted CTS: my buddy has this, it drones too much, so Im out.
Full unitronic with their catted dp: also sounds dope, but a tad too quiet at WOT
Full CTS with their catted dp: yuk yuk yuk.
AWE Track edition with an unknown catted dp: this shit sounded EPIC. Random guy at a car show in Dallas had his GTI with this setup. Ultimately bought this exhaust and the Uni catted dp. No regrets, I putt around town with a nice authoritative sounding exhaust. Immediately recognizable to those that know, that your car is not the typical sounding GTI. At WOT it absolutely screams, I smile every single time. Also, mid powerband throttle blips will snap necks of those within earshot, it's very amusing and entertaining.
