[Humy]

I had MAD secondary catless downpipes installed this past Monday. 1st performance mod on my M8 Comp. I can hear the turbos whistling now and the gurgle and pop sounds amazing especially going through under passes. Love it. No trouble codes or tune needed to threaten my warranty. I paid around $250 for the pipes during Black Friday week and a little under $800 for install. I had another shop quote me ridiculous $2K for install, so I am happy.
