K&B 61 aluminum muffler in nice used condition.  Mounting threads are in excellent condition, has the pressure tap fitting in it.  No damage, cracks, or modifications.  One of the fins on the bottom toward the exhaust tip has a mark in it see pictures.  May have just been a molding flaw when the item was made.    

The item will be well packed cardboard box and shipped by USPS Ground Advantage.  Will be listing more RC items over the next week and will combine shipping cost though a refund after items are packed.  Thanks
