Noiose wise they should be pretty close, maybe a little louder. AS for the hp# getting rid of your stock plastic elbow will help some, my kit replaces everything. I did some testing with a kit like the one you have and my complete kit beat it by 4hp at the tires, not much but still there.Originally posted by kpaske

I've currently got a PV muffler and a Calmini cone filter setup and although switching to the Calmini introduced a bit of underhood noise, I hardly notice it. The PV is what really makes it a loud machine. How do your intakes compare, noise-wise and HP-wise, to a regular cone filter setup?
