Akropovic Exhaust System

Anyone see a decrease in miles per gallon after install? If yes, how much?

Anyone have any problems with the Service Engine Soon light coming on?

^ You'd have to put on the Delete R to keep the cel from coming on if your using the full system.....


The only decrease in MPG your going to get is because your throttle foot is going to get heavier so that you can listen to the beast with its new lungs...

Beat me to it too.
When I had my xpipe with the oem muffler, my mileage went up quite a bit. It seldom read below 18.2. Once I removed the xpipe and added the AA rear, mileage dropped to 16.4.

The difference was my foot. For the former, the rasp and fart kicked in at 2000 rpms, so I was switching gears at 2000+. Once I went to the AA, I started switching gears at 3500 to 4000 because I liked the music.

On the highway my mpg went up. I verified this with my own calculations. Using similar avg speed (cruise control). However I love the sound so city driving suffers.

Interestingly, track mileage went up to 9mpg from 8mpg.

Meh, it could have gone up, but I don't really care what my mileage is so I never tracked it.
