Hello, I am new here and my wife picked up a new Focus about two weeks ago and although its her car I can't but mod it since I also drive it. I noticed all of the european ford focus's have a dual exhaust set up. After some research I found they are basically using a transverse muffler. I used a Borla muffler and some 3.5" stainless tips. A local muffler shop did the install. I removed the middle muffler and dropped in a K&N cone filter. Here are some pictures. The car sounds so sweet and there is no audio drone at any speed.
Parts List: Borla # 40477 2.5" 2.5" 19"X 5.5" X 10.25" Transverse Mount Split Exit $$ 265.00
Tips Ebay $$ 29.00 each
