single exhaust choice ?
If you do your research, supercharged cars dont like super free flowing exhausts. Superchargers prefer a bit of back pressure to make power. If your car was turbocharged then you would want a super free flowing exhaust.
Another vote for Berk. Get the HFC version and you'll be golden. Honestly, like others stated, I don't find my Berk crazy loud. But sound is subjective so what I think is loud and what you think is loud will vary. I will say this. I had a Invidia dual and it was definitely louder then my Berk.
