Default MPG after flowmaster and coldair intake

I know a muffler will not add alot same as a coldair intake but there has to be some change even if it's small..so what kind of change did u see with Muffler and airbox? Or either or if u did only one

My mileage went down the drain after adding my Magnaflow, because I can't keep my foot out of it! It sounds so SWEEEEEEET!

Same here.

I wouldn't waste money on a CAI.

They make claims but none will make a guaranty. So, save your money.

If you are looking for performance or mileage gains, go with a tune. Doesn't cost any more than a CAI & exhaust but will achieve measurable gains,

All parameters are controlled by the pcm. Cai and exhaust wont give any appreciable gains. The stock airbox is a cai btw.

I noticed 1-2 mpg with catback dual flowmaster and K&N intake on my 2011, but noticed nothing but louder intake noises when I just had the intake. Hard to say if it was the combo or the exhaust... Regardless I won't do intakes on any vehicles henceforth. And I plan to do exhaust on my 16. Not expecting any performance gains; Hemi's just sound good!
