Review on Dynomax 36484 Performance Exhaust Pipe Spout by Smiley Edwards

Good product, quality seems good, really strong clip. This following comment in no way reflects the seller. Someone wrote in their review that this will pinch a 2" or smaller exhaust pipe unless you put 1/4" metal washers between the exhaust pipe and the exhaust tip. I don't understand how this is even possible! I listened and now I can't use this exhaust tip. This is not the seller's fault.
