The Borla is by far the best sounding system so far! The S-Type wouldn't be too bad. I have no idea why these other companies put out systems that sound like ass and drone like a ****.
Its because most aftermarket exhaust companies dont understand engine frequency firing order and tuning a silencer for a vehicle. Corsa and Borla both have close ties with the OEMs, and have lots of engineering experience. Im excited to hear both of these systems in stock. I will not settle for a subpar low grade exhaust system though (poor bends, no heat shields around the spare tire, and incorrect weld wire/hanger rods used...these will rust out quick in the midwest)
