Believe it or not I found them at a local Pep Boys ($40 ea). They are about 10 inches overall in length; which is much shorter than ones I have seen elsewhere. They look exactly like RM Racing's DTM exhaust tips which, IMO, is how the OEM exhaust should have looked in the first placed. You will need to purchase an adapter ($1.99 ea) that reduces the exhaust tip from 2 1/2" down to 2" so that it will fit on the pipe. You will also have to cut off 6 inches of pipe from each side. Otherwise the tips will stick out too far from the rear bumper. A good place to cut is right where the pipe starts to bend and angle downward. This will keep the exhaust tips nice and flush with the rear of the car. Once you have them in position just weld them into place and you're done.
Save the 6 inch pieces of pipe that you cut off in case you ever decide to return it to stock by simply re-welding them back on.
