I am kind of new to the 7, but I thought that a downpipe alone will not cause you to fail emmissions. I am about to install one on my 7, but I want to still be able to pass emmissions. Has anyone else had problems passing with a DP?

Denatured alcohol does work wonders for passing those tests... I dropped my emissions by about 95% by running it in a 1:6 (alc:gas) ratio with high octane gas.

if you are talking about running the car with it, i think too much alcohol in gas could cause problems.
ive tried the ratio of 1 gallon of alcohol to 2 gallons of gas before and had to drain it due to terrible bucking/surging.
