Re: Ramhorns vs. Headers for MPG gains?

Andy is right...it should help but in all reality it didn't for me. I now have ramhorns and have gained power on the lower end and the mileage is the same...11 mpg with a 3.07 rear axle.

I'll never have headers again at this point...they're just too much damn trouble. I haven't tightened a heeader bolt in weeks!!
