Mufflex 18" mpg up or down? Low end?

[X Gixxer 1000 X]

I searched this but couldn't find the exact thing I was looking for. I am constantly on the road and I'm not looking for a loud exhaust. I've pretty much decided on the 18" mufflex but I am trying to find out if it helps get some more mileage or not. If there is no increase or decrease fine, but I don't want to hurt mpg either.

Also I've been reading people have lost low end with some exhausts. Will I loose any with the mufflex?

I've got the 18" on my truck, I love it! Nice roar to it when you get aggressive with the skinny pedal, and just a nice little rumble to it when you're just cruising. Never really noticed a difference in mileage with it

Any loss of power down low??


Also. Where did you get your interior lights and tag lights?

I've never known my truck to lack low end power, she's always pulled great no matter where in the rev range I am. Could have been my imagination, but I think I actually got a noticeable bit of top end from the swap, I know it was a lot quicker to pick up speed on the highway after I changed the muffler.

I got my LEDs from superbrightleds.com. I forget exactly where, but there is a thread around here with a list of bulb numbers
