I will visit those websites and check their prices.
I received a nice email from a gentleman who works for this company called germanstar, their website is at http://germanstar.net/exindex.htm
They have good prices and also warranties, has anyone here ever dealt with them before. Please let me know how the transaction went.
They are selling the catalytic converter for $484 and also offer a five year warranty on it. They also say it is made of stainless steel and will pass both federal and california emission tests.
I'm not a shill but they also sell a lot of MB parts including rims, european headlights so you might want to check them out.
