2005 GTP and looking to update the exhaust since the stock exhaust is about to rust out. Small holes are forming and I've been plugging them with the Permatex muffler and tailpipe sealer, which works really well by the way.
Anyway, I'm wanting update the exhaust from front to back (3 in), so I need to know what all I need to get.
3" Catback exhaust for 04+
3" Downpipe (and 04+ required accessories)
Anything else required or recommended?
