SOLD
Bought the TopSpeed muffler from their ebay store a few months ago. Got it cheaper than usual since they said it would be misaligned. Turns out the mounting plate was miswelded. I installed it as it was and was alright to me. If you were really worried about the alignment it is nothing that a dremel wouldn't be able to solve.
Looking for $180 + shipping. Used it for about 400 miles. Selling my boxster now for a Lotus Elise so putting the car back to stock. Muffler is completely "broken in" at this point. Sounds pretty good!
