Looking for some recommendations on an exhaust for the pathfinder. I’ve installed two previously from Rockauto, but they don’t last. The insides fall apart and it starts to rattle. I plan on going to an exhaust shop to have one welded up, but any ideas on a nice sounding muffler? Should I keep the resonator at the back also?

The Northeaster Exhaust system I bought was a complete cat-back install that comes as a complete bolt on set-up. The intermediate pipes were not a perfect fit so I had those welded to the muffler to get them better aligned and allow the system to hang straight. That service only added another $50 to the $300 I paid for the front resonator pipes, intermediate pipes, muffler, rear resonator, and gaskets. Everything bolted on just like the stock exhaust.
