Is there any noticeable improvement installing a 2.25 cat back exhaust system? What are the hp and torque improvements over stock? Does it help increase gas mileage? I'm thinking about using Dynomax super turbo round mufflers #17741 and have a custom 2.25" exhaust made with an H pipe. Less than 1/2 the cost of a Borla system.
