replacement tailpipes

Does anyone know where i can get a set of replacement tailpipes for my MAC exhaust. I got a 2001 V6, and the setup connects right to the y-pipe. I've had it for less than a year and they are all rusty. I cant find any on MAC's website, and ones i did find were about $160. I was also wondering if i can upgrade to maybe 3" tailpipes, and stainless steel. Anyone know?

Yes it is the chrome tail pipes. I was reading the warranty on their site and found this "MAC's guarantee on any product shall be limited to replacing the unit or component thereof, provided it is not damaged by impact, neglect, modification, improper application, exposure to corrosives, or deterioration caused by weather or wear." http://www.macperformance.com/store/PDF/warranty.pdf I dunno, the rust formed because of the weather, I'll give it a try. But incase that fails, anyone know where I can get a nice set of new tailpipes?
