Well when I went to the muffler place to get the exhaust installed including the HFC, they must of kept my OEM cat right? Or do they dispose of them? I'm now looking into going dual so I really need to know how I can do that. Is there anyway that I can split the exhaust pipes and basically put another set of tips on? I'm don't care about performance with the dual exhaust, mainly the looks of it. Any suggestions on how to get it done?The only thing you can replace it with is an OEM cat. Most, if not all after market cats are high flow.
Maybe someone on this forum could sell you theirs?
