Ive had my HKS dual exhaust for a few months. I love the sound, not too loud or quiet. I read somewhere on here that an aftermarket exhaust would equate to better mpg, but ive actually gone down to 16 to 17, whereas I used to be up in the 19's on my meter. Is this normal?

Also, i thought the hks was the best non f/i exhaust available, or one of the best. But ive read from people who own it that they have lost some low to mid-range power, could someone shed light on this?

Thanks

Any intake or exhaust mod will alter horsepower and torque chart. Only way to figure out how is to run before and after dyno tests.
