So here is my review thus far.. I have about 300 miles logged on the corksport sri, exhaust combo. I inititally wanted to just install the sri, do a review, then add the exhaust.. to evaluate seperately. but im impatient and with work and kids, time is not on my side so i installed them both. The immediate thing i noticed was a vast improvement on 2nd gear. I hated second gear. It always seemed to bog down on me and took forever to get to third. The CS combo has really helped in that area. Aside from this, the car definitely feels improved. The sound of the exhaust is beatiful. I used to have a Tanabe touring medellion exhaust on my Fit.. I thought that one was nice.. well this one is so much more mature sounding. If you want rattle race car sound, this is not the sound for you.. It is a deep humm, queit , then gets loud when you floor it, but not annoying loud. I also LOVE that its a cat-back. The exhaust lines up PERFECTLY. Even my shop guys were really impressed. They initially were going to charge me a more for the install because they said that everybody that takes them internet bought exhausts never fit perfectly so they would need to tweak and bend it to fit. To their surprise it lined up perfect and wanted info on Corksport. The SRI I feel is what is responsible for the 2nd gear performance gain. Overall I am impressed and happy with the two products, do not regret the purchase, and if I had to do it again, I'd get the same setup.
