I think I might have to go with this setup.

The sound is quiet when cruising and very very loud under acceleration. It is very high pitched as well. NO DRONE whatsoever.

crappy vid but you get the idea:

Thanks. Do you have the stock muffler?

1. No drone -- I do not mind the exhaust being louder, but I daily drive my car and I do not want pipes that produce any significant level of drone; and

2. Performance -- the point of this mod would be to liberate additional power, so proven performance gains are important.

Please provide recommendations on which setup is best and why, together with any other advice you can offer.

Thanks.

The Fabspeed setup is a great setup that makes good power and should be a great compliment to your SC setup.

Just choose what you like! Hear the clips online and pick the one that suits your taste.
