Hell yeah! Sounds greatJust got mine put on with the Borla ATAK exhaust. My neighbor has the Borla ATAK exhaust with stock cats. We'll work on getting a side by side comparison video, but suffice to say the GTHaus makes it noticeably louder, especially the cold starts.
First Cold Start
Great to hear! Enjoy.Bought a lightly used set of these gt haus cats and wow, really took the atak to the next level. Cold starts are real loud and has a sharp bite at initial start. Quiets down to a nice chop at idle (almost a cammed sound), downshifts burble and up shifts burp and growl. Cruising on the highway is similar to the Borla atak alone with no drone but hammer on it and it barks.. almost nascar sounding. Super happy with this set up and fit like a glove.
