Thinking about using catalytic converters
I'm thinking about using catalytic converters with my LS3 525 crate engine. I want to use them primarily to cut down on exhaust fumes, and then maybe tone down the exhaust volume a bit. I talked to the tech at Magnaflow today but he didn't sound overly confident with his answers so I thought I'd double check here. These http://www.magnaflow.com/products?partNumber=59959 are what I'm considering using. So my questions are
1. How far away from the header flange (long tube headers) do they need to be mounted?
2. Will I need any type of heat shield?
3. Is there any type of negative side effects or other issues (tuning) from using cats?
