"Bought a 3A racing stainless steel dual clamp on tip from Muffler Mall. Item arrived in decent time, installed well and looked good on my 09 Toyota. However, when my 3A racing tip, which is supposedly "high quality stainless steel", began to rust, I contacted Muffler Mall by email and sent them pictures. I have to polish the tip every two weeks to get rid of spots that are as large as 3/8" in diameter. In ten + years of having stainless tips, never had rust on the surface of the tip...bolts or clamps yes, but not the tip itself.

Anyway, Muffler mall responded that they would speak to manufacturer. No response for a week. I emailed again for update. No response. Never heard back. So Muffler Mall's policy seems to be that if there is a problem, ignore it and it will go away. Stay away from this retailer. "
