        Having one on mine as well...I would say really good! I like the option of changing the sound by changing the bypass plates. Eventually, I'll get the electric cutout designed for the Borla.

            Borla is a great option. Craig has it with the electric cutout also, and its pretty trick. If Borla is out of your price range, check out the Loudmouth. Can't make it quieter on the fly, but its hard to beat the flow without going to true duals.

                I'll have to get him to post his results. He said he's been experience some poor gas mileage, but its also because he's been jumping on it a little more...gotta love the sound

                  Well, let's just say I got the worst gas mileage I've ever gotten with the car. I got 197 miles on a full tank I probably had a gallon or so left though, so that means I got 14.0 mpg. However...during most of the fuel run, I had the cutout practically closed. It was only a tiny, tiny bit open because I was changing the switch. Also, most of this driving was city driving (only about 40 miles on the freeway). And I've always had this nasty low end stumble that could contribute to the lousy mileage. What kind of MPG are you seeing...er, KMs/gal, KM/L, or whatever the conversion is

                    i was being a bit sarcastic i can get 200-250 miles to a tank depending how i drive the car the only time i close the cut out is when i leave for work late at night or get back very early in the morning but when i first fitted the system i did drive like a compleet ahole holding the car in first and second because it sounded beter. the thing is when i get in the car it is like the red mist i have to drive everywhere quickly

                      LOL I used to leave it 1st and 2nd to make it noisy when I had the stock system...out of jealousy of all those with aftermarket systems!
                      When you're doing that with open Borla, I'm sure you're making fellow drivers go crazy in traffic
