Hey Guys. I have been noticing recently a lot of black carbon deposits on the outter rim of my exhaust and just today I noticed that it is starting to accumulate on the floor of the garage near where I park the car every night. I was just wondering if this meant that there might be a problem with the exhaust system or if it was just normal, I know that the stuff can tend to accumulate if you go WOT all the time, but I really dont. I have an aftermarket exhaust (Billy Boat) and obviously I don't have the CL, but my engine is the 5.3L V8, so any feedback would be appreciated.

Thanks

On startup my car belch a fair amount of exhaust, I guess it's normal to get carbon buildup.

Yeah i get a decent amount of black soot on my exhaust after a few days of driving. Never had it get enough to accumulate on the ground however you have a much larger engine so more soot may be building up.

How often do you wipe them down?

I think their is a need to do WOT now & again to reduce the carbon buildup...

I run a bottle of injector cleaner & high-test once every 3-4 months...and basically take a ride down the freeway at unsafe speeds to blow-er-out good.

I wipe them down every time I wash the truck, which is usually once a week. I also run 89 in the tank all the time, so I use a higher grade fuel, but I like the idea of a fuel injector cleaner, I bet that might clean it up a little bit. I might try that with my next fill-up.

Thanks for the replies.

On startup the car is in a closed loop cold start mode, which is richer than once it is warm. It is normal.

its normal but its also the gas, casue the higher the octane the less of the other sh!t so more fuel burns

How often do u get on it...ya know WOT. Try it sometimes and upgrade your fuel every other fill-up...you'll be fine.
