so i'm looking to get a custom cat made
i want a 2.5inch inlet with a 3 inch outlet
any one have any suggestions for a 3 inch cat?
i'm getting tired of endless emails with a certain company but that could also be my fault but still when i send a email i'd like one back in a timely manner a day or 2 not having to send 4 or 5 emails before i get a response then no responses for days and it starts all over again

 

Just buy a 3 inch in/out cat and weld a 3in to 2.5in reducer on one end. Weld on your flanges and you're done.
