I went with the Fast Intentions 12' resonated CBE with Stainless mufflers and let me tell you it sounds amazing. The difference from stock is like night and day and observable from your first start up. The exhaust is much louder until about 3000 rpm and sounds increasingly more loud and aggressive once you start getting over 3000 to 7000 rpm. Go with Fast Intentions, their customer service is FANTASTIC and Kevin will take care to explain everything about the exhaust and recommend the best setup to obtain what you want. I will be getting test pipes from them later on down the road. The big thing for me going with this exhaust was the reviews regarding their service and craftsmanship. You cant go wrong with the Fast Intentions CBE.
