08 Commander 5.7, 12,000 miles and new to me. Sewing machine quiet and needs a little exhaust help. Anyone run the stock muffler without the resonator? What is the quietest after market available with resonator?
Also, any performance increase with a std K&N?
I just got a magnaflow exhaust for my 06 3.7 jeep commander. I was wondering if anyone knows of average costs to put this thing on. I called my local jeep dealer and they said they don't put them on because their not able to warranty installation. Its not a cat back or anything just that 100...
