The fumes aren't a problem now but wait until spring. You'll definatly notice it with your windows open and it actually seems to be worse moving than standing and idling. I tried running without a tail pipe for a while and didn't notice any fumes at first. I popped open my sunroof while driving and Yikes!

 

if you run with just the rear window open, the fumes will be drawn into the vehicle. make sure you have both front windows open and your fan set at least to medium high to help move air through the cabin and out the gate window. im hoping people will understand this is a fair weather situation, it does get deathly cold doing this in the winter!!

My Taco exhaust looked like sheit too so i took a big wire brush, scrubbed it real good, then took some high temp. flat black paint and sprayed it on almost to the muffler. Looks a hell of alot better. Only thing is, if you touch the pipe you get black powder and paint on your hands, but why would you touch the pipe anyways? Cheap and easy!
