Hi there all,

Today when I went out to my truck I noted that my new chrome exhaust tip was not shining. This was expected do to the rain that has been falling for 2 days now! What caught me off guard was that there was a ridge of brown dyscoloration arround the edge. On further inspection I noted that there was a rather large amount of soot built up in my 5 week old pipe! The truck is new to me so I dont know what the trend is. However Im wondering if my poor mileage could be ralated to a rich mixture, the same that is depositing sed soot! Any thoughts?:confused:

If there is a link, then what is a probable cause for a rich mixture?

Thanks

It's normal for the soot to build up, even brand new cars with chrome tips have the same problem, just wash frequently

 

I've had this problem on my Borla - ongoing. I use Chrome Polish when it get's bad.

 

Thanks for the input, but I feel that this is a bit more than a well tuned engine should be turning out! BTW it is a factory new longblock with only 31!

My borla exhaust does the same thing.....a lot of soot and gets a crusty brown brown color......When I wash it, I use chrome polish and then my dremel w/ the polishing attachment (felt donut thing).....shines right up like new......

 

Travis,

Reading the spark plugs would be a more accurate way to tell if you're running rich. Pop out a plug or two and make sure they're light brown/ tan and not dark gray/ black or wet or sooty.
Let us know what you find - there are a number of possible causes for a rich mixture.
