Has anyone ran a K04 on stock catback setup? I'm thinking of going K04 this spring. I currently have a stg1 APR tune, intake and ARM FMIC with an SPM street TBE (without a cat). I ran the stg1 tune with just an intake and downpipe before putting on the SPM TBE setup and I didn't notice any gains in power, just an increase in noise and drone. I daily my car in traffic and I'd love to cut the drone out by putting the OEM catback back on, just not sure if its up to handling a K04. My guess is that its not but hoping for someone to say otherwise... because drone sucks...If I don't go K04 I'm definitely putting the OEM catback back on this spring. This old man cant take the drone anymore...
