I have a 2007 v6 mustang and I recently got a Pypes true dual exhaust kit making it, dual exhaust from the stock single exhaust and giving it a much better sound.i can see the mpg I get on the dash and I was used to seeing 16-19 but when I looked it said 13.8. I have had the exhaust for less them a week and sure, I‘m being a little harder on the gas to hear the noise but a loss in mpg is a lot to lose just to be a little harder on the pedal.my hypothesis is that I am losing back pressure/force because the air is coming out two pipes instead of one, but I am no car expert at all.why is this happening? and how can I fix it?
could be a glow plug situation! additionally coolant sensor could reason this fault. Get it clinically determined at a storage. There are fairly some garages close to me which will run a loose diagnostic. it may additionally be the MAF sensor. in lots of circumstances you will get to a undeniable rev selection and it stutters then options up previous this. in spite of if it somewhat is not examining wisely the automobile over-fuels. is additionally a on/off fault as you defined. As suggested must be air filter out, yet often non-end issues if it rather is undesirable. Sensor on exhaust gases, yet returned could regularly instruct all time if lifeless. i think a sensor or undesirable earth!
If you have been heavy on the throttle, that is all it takes. I owned a SHO that could average 27 mpg, but if I got on it the MPG's would drop to half of that. As for back pressure, not. A change in resonance, yes. This affects savaging of the cylinders, the better this is done the more fresh air mixture is used to fill the cylinder on the intake cycle.
