I Paid 99.43 for the muffler from www.a-1parts.com after tax and shipping it came out to 112.10 and that's leaps and bounds below the 700ish i would have paid for the Borla. It is just a muffler, not a catback like the borla, and you will have to have a local muffler shop install it for you because the magnaflows are a center inlet design and the current MB muffler you have on there is a right side inlet design. i paid 60 dollars at a local muffler shop and they installed the new muffler, installed the old stainless steel tips and gave me a lifetime warranty. The muffler part number from magnaflow is 14220 and its one of their stainless steel designs. I highly recommend it, but i would really like to hear the borla both inside and outside the car to make a fair judgment. but the way i figure it, i saved 500 dollars and that's enough money to chip the car and get even more performance. good luck with whatever you decide to do!
