This year I decided to get a set of open exhaust so I ordered a set of Re-Cored Harley exhaust. well it was a bad Idea. they sounded good from the start until the left pipe started to sound like a tin and a lose marble. I contacted the seller. a few time and I got back very short responses. this guy will avoid you when your exhaust starts to fail. he never once tried to fix this for me. so I pass this to you learn from my mistake do not buy from this guy or his Ebay site. he will claim to make you satisfied but he won't. I've seen other post on this subject. to this date I have not gotten a call or email back from the man BOBVIC
