I was wonder how bad is mpg affected after installing catback and j-pipe. I've been thinking of going Endless since I don't want a loud sound. Thanks

 

if you're light on the throttle you can see a 1 mpg gain!!!

if you're heavy on the skinny pedal you can see the fuel gauge drop before your eyes!

 

right after it's going to go down since you'll be finding every excuse to hear it

 

htown holdn it down!

reppin that mo city!

 

Your mpg should go up unless you want to hear it all the time like me. As these guys already said haha deleting egr would bring you down 1ish mpg city don't quote me on that though. I've noticed no change in mpg since I owned mine but only had it for 1month before the j-pipe went on

 

Excellent. Thank you for the feedback all.

MoCity reppin here too 👍
