This is a set of authentic Milltek Sport 4" stainless steel exhuast tips that were taken off of my Milltek system. I replaced the Milltek tips with a different style tip of my choice. The tips also have a Milltek Sport logo lasered on them. These tips can be used on any 335 or other vehicle. The inlet size is 2.5, outlet is 4." You can have your stock tips removed and these welded on very easily by most any muffler shop for around 30-50 bucks. I'm asking for $60 shipped to your door. Here are some pics of the tips, and the tips when they were on my car.
