I developed an exhaust leak where my Stock Y pipe meets my catalytic converter. Dealer tells me that the only way to get this Y pipe from Chrysler is to get the entire section that contains the cat which costs nearly $700. So my question is this 1. Can I just buy an aftermarket Y pipe like magnaflow and get this to fit with my cat? 2. Do I need to buy a new cat back system and cat with new Y pipe? I was told that if I didn't want to pay for the stock Y and cat the dealer had a "guy" who would build me a new pipe with flange to connect to my cat for $440. That sounds crazy expensive to me. I'm looking for the most simple solution? Any thoughts I'm thinking about either an summit racing system or the American thunder system but what do I do with the cat and a leaky Y pipe?
