hello

my car is a 1999 a4 quattro 1.8t. i love it

the catalytic convertor has cracked and, having been welded once and failed again, needs to be replaced. the mechanic who will do the work quoted $800 for the part which seems excessive.

can anybody point me to a source of an aftermarket, direct replacement part which is california legal?

sincerely grateful for any pointers.

thanks and regards
