I put a flowmaster on my GMC Yukon and absolutely loved the improvement to the sound of the vehicle, but the fuel economy went into the toilet. Before I was getting 17-19mpg... after the flowmaster and K&N install it went to 12-15mpg.... no noticable power or torque increases, but sounded mean and not too obnoxious.... I'm wondering if the x-pipe conversion on my 4.6is would have the same effect?


...what's the real impact on fuel consumption (before vs. after an x-pipe)?

Hahahahahahaha! Classic!

This complaint happens ALL THE TIME! You get an exhaust that sounds bitch'en... so naturly, you get on the gas more often so you can hear it. And your MPG goes right down the shitter. I have heard that complaint 1000 times, and this is 99.99% of the time the answer.

Watch your MPG gage on your X when you drive..... .5 inch more throttle.... under load... like going up a hill, and you roll it on, (like if you had exhaust this is where it would sound the meanest) your MPG is pegged at the bottom.... with just a smig more throttle.

If you put exhaust on, and its "better" (more HP or torque) your MPG got "better". hands down, no contest.

i just got my X put in the xpipe....i went with 2.25"...pretty happy with it..i hear the v8 sound but to exaggerated with the noise...all in all happy...will post vid....>>>

comment me if you this quote is true....


""""h-pipe has a deeper growl, x-pipe has a more higher pitch type sound.
h-pipe for more low end power/tq and x-pipe for high end power/tq""""
