I recently installed mbrp catted long tubes on my 2016 gt. I also have the mbrp catback street series with H pipe. It's a lot louder than I anticipated, (morning starts for work wake the whole house and probably the neighbors) and it has gone from a deep sounding exhaust to raspy as hell when you punch it. I'm seeing if anyone has catted long tubes and a catback that hopefully has a video clip or advice on what will give me a deeper less popping sound to my s550. Thank you
