I have had a couple of fellow Mada lovers ask me to post pics of my dual exhaust from underneath so they could see how close the dual pipe comes to the spare tire. The shop I went to knew what to do to combat the heat of the pipe, they wrapped it so the heat wouldnt transfer to the spare and bust it. It is VERY close but I have had NO issues with it. I have taken long trips also (Tx, Vegas) where I was driving all day and I still havent had any problems. Hopefully these pics will help all of you wanting duals out. Oh, I have a Flowmaster 70 series system.
I got the Raiders hitch cover at a local truck accessory shop. I live outside the Bay and have been a lifelong Raiders fan. With the Raiders nationwide popularity, you should be able to find one locally.
I dont know the exact size of the piping, I do know that it was standard with the system, they just had to bend and configure to go around the spare. The sound is barely above stock at idle and cruising speeds, nice and throaty, growl when you step on it. I havent experienced any back pressure.
