Great exhaust minus the drone and if you don't live in an area that salts the roads during the winter.

I picked up a used one a few months ago. I had to add and AR20 resonator because it droned a lot without it. It is much better now.

I have a magnaflow setup that came with my car when I bought it. Don't know what part number it is, but it def has that masculine tone although it does drone. I think i'd be going back to stock soon and selling mine cheap :/

I used to have a Magnaflow catback. It was okay. Now I have catless headers, 200 cell cats on Borla sec.1&2 and Magnaflow muffler. Nice and loud and raspy. Just the way I like it.

For the record, I found that my Magnaflow cat-back with stock headers droned pretty badly. HOWEVER, with catless headers, the drone is 95% gone. The exhaust is loud on the highway, but it's nothing like the drone.
