Please pardon my ignorance(encourage. But hopefully you can understand how the uninformed would want some "proof" even if it is bull shat. I totally agree on their exhaust, looks good, sounds good, quality materials and techniques(cool). I want that system on my car, I just have to burn mine up first to justify the purchase for my wife. BTW chibana, do you have this short ram on your car now? Any heat soak problems? that is my biggest worry on an sri, but i am not sure about a cai because of hydrolock. I am more than uninformed on this stuff, I only have clues because of what I have researched(dunno).
