I like the SVT exhaust cause it's all mandril(sp) stainless steel. I've left it all original and people argue with me that it is a V6. hehehehe anyway before with just the intake I got 23 to 25 mpg and when I drove it 6.5 hours after it installed from the base to Fallon Nv wich goes over Donner Pas at Lake Taho it got a little over 30, but normal back and forth to work are mid to upper 20's. Also I did notice a difference in power. But those are just my inputs.
Beleive it or not but I drove it 165 miles like that at night and got some weird looks.
