black exhaust pipe and muffler

i've got a 2008 rugged trail prerunner double cab, and when i got it the exhaust pipe and muffler were black. at first i thought some type of coating was applied to the undercarriage of the truck, cuz it seems like it's black everywhere under there.

should i be worried?

The muffler looks like it has overspray on it, the tail pipe just looks like rust/road grime build up..i wouldnt worry

 

what's overspray used for? the pipe seems really black for just road grime build up doesn't it? i've never really seen an exhaust pipe like that before

 

I would be more concerned about the lack of air in the basketball ...

 

Looks like the overspray could of been used on the frame prior to you purchasing the truck, kind of like an undercoating or paint..as for the tailpipe, well i dunno..was just a speculation that it could be road grime..you have to remember the tailpipe is behind the tire too

 

Overspray is where something was painted but spray from the painting got on something else that was close enough in proximity for paint spray to drift on to it. It can happen when spray painting something when there's a breeze.

 

It's good reason to swap out for a cat back exhaust

 

The last owner prolly painted it black

 

They make black in a rattle can to spray BBQ's. Its good up to 500 degrees I think.

 

My tacoma actually came with a black exhaust also. Thought it was odd but didn't care too much because it was shortly switched out for a trd cat back exhaust.

 

thanks everyone for the tips. i do plan to swap it out for a trd cat back exhaust eventually, just not right now. maybe next month.
