Who makes a direct high flow cat replacement for LS1s
Who makes a direct high flow cat replacement for LS1s Well my passanger side cat is banging around inside so I need to replace it. I was wondering what company makes a direct replacement for my 02 Z or im just gona replace it with a stock one. If anyone could help thanks
Magnaflow/carsound makes direct replacement cats. I don't think I'd just put one high flow cat on the passengers side, without replacing the drivers side also. The direct replacement cat for the passengers side is like $300 bucks though. 
You could just weld in one of their universal high flow cats though for cheap. You can find them for less than $60. I've got a universal one welded into my passengers side, and a direct fit one bolted into the drivers side.
