Hey guys, I just got my exhaust upgraded to dual magnaflows and deleted the resonator (for now). I wanted to test without the resonator to see how it flows .The sound is raspy but the sound don't bother me I like the sound. I stayed with the stock size piping. I did notice it open up alot? If i go with bigger pipes with that decrease or my gas mileage?

Now Spark plugs, what is a good firing spark plug? I just purchased my 05 Max on 7/31/09 with 64,000 miles on it. I know i the manual says change spark plug at 100K. I want to change them on now. What do you suggest?

Thanks for all your help.
