I checked my gas mileage today when I filled up. 24.7 mpg for my V6. 75% was freeway driving. I recently replaced both o2 sensors. I know bigger front wheels and tires make a difference in hurting economy. I also know that wanting to hear the Vtec hurts economy too.
I found a 2001 CL-S being parted and want the mufflers. Should I get the cat-back pipe as well? Are the factory headers better that the Honda manifolds?
I found a wrecked 2001 CL-S on Craigslist. I got the front strut bar installed on my 01 V6 and it makes a noticeable difference in reducing cowl shake and probably handles a smidge better. Proably the best bang for the buck so far.
