I'm thinking this is the right place to put this... Anywho my truck from day 1 has had black soot build up on the tip of the exhaust pipe, reaching no futher than about an inch on the outside, and the inside is completely covered. I can wash it off and it will just build back up in a few weeks. I'm getting about 16 mpg average with the way I drive my v6 so I'm thinking it's just a byproduct of a v6 using that much gas. The dealer told me everything's normal, and they didn't see a problem with this black stuff. Anyone else got this going on? I just recently added a kandn fipk and it seems to have made it worse, but I have been taking advantage of that extra power. I keep fuel system cleaner going through regularly and change with full syn. oil every 6,000 miles, plus I've had a kandn filter in it from day 1 now it's a bigger filter with the fipk. :help:
