I know it's a great piece and I purchased it because of that, but is anyone running it on their daily driver? I don't care about the sounds it makes or anything else other than the fact that I drive a lot with my child in the car and although I do know that it opens when the wastegate opens, I'm wondering about the toxicity of the fumes it emits.

Also, I have an ETS 4 inch front mount. Is there any problems with fitting a lower icp with the Shearer o2 dump?

Thanks!
