does anyone with a ZTUBE notice any increase of MPG ?

 

MPG will suffer horrifically with the addition of a z-tube.

I keed. I keed.

In all seriousness, it's likely you'll get worse MPG due to changes in driving habits.

 

soooooooooooooo no ? lol

 

The extra growl will cause your foot to play with the accelerator more, accelerating wildly just to satisfy the desire to hear more. Your gas mileage will suffer greatly!

 

Agreed.

Theoretically, you should get a gain (more than likely minute and undetectable) in gas mileage. However, as said above, the fact that you will hear that amazing sound that you have never heard before, you will decrease your gas mileage by driving it like you stole it.

 

haha i get what ur saying , but overtime i could get use to the growl. but i hate all the plastice crap in the engine bay, want to relieve it with just a single tube, iono within a month im getn one

 

wow, just speachless..........................

 

the only thing that will improve MPG is a lighter foot and weight reduction.

 

ummm, no. it's a round piece of plastic that replaces a more muffled round piece of plastic.

even if there is a VERY minor gain, it would be too insignificant to notice.

 

Dammm......I just ordered a z tube & JWT pop charger

I'm sure the rumble will be worth it

 

If you combine the z-tube with a JWT pop charger, MPG will go down drastically!!! Somehow that combo added 10 lbs to my right foot...

 

Installing the Z-Tube is kinda like installing an aftermarket exhaust system,
you brain listens to the sounds and enjoying it your right foot reacts. Unless
you're hearing impaired mods will not increase gas mileage....

 

I'm "speachless" too; lol.


(speechless*)

 

Oh it's worth it!! Hearing that roar is SO addicting and worth every penny

 

it's not really a rumble... more a high pitched whine/whistle
