Hello I own a stock 2004 g35 coupe base , im still trying to figure out how all this works. But my cars cats were clogged so I gutted them but now the smell is horrible, was going to buy cats from jcarpart for 150 or berks hfc for 550 , any thoughts appreciated

 

Hey welcome!

Berks are pretty popular on these cars. Im eventually gonna get some high flow cats too. Looks like they are a pain to install though.

 

Welcome buddy
