I'm looking into installing a turbo back exhaust for my car and I am considering installing a 42DD downpipe with the remaining catback being borla. I haven't heard of anyone having this combo, but was just double checking to see if someone does, and to see what people think of the combination. I am looking for a deep smooth tone if possible. A sound clip would be greatly appreciated if possible. I am torn between this combo or just going with the 42DD turbo back exhaust.Thanks in advance.
