As much as I like the looks of the Magnaflow muffler that many go for that addresses the sad factory Y-pipe replacing it with 2 separate pipes entering the muffler, I don't want it for the reason that my Pathfinder is my long haul family car and I don't want the sound that comes with performance mufflers. I also don't want to have to turn up the volume to overcome any exhaust sound.
I do have a Magnaflow cat back system in a car with a main muffler and 2 resonators with 4 tips and it sounds great on that car and that car is fun to drive and drive hard. When I'm in the mood for a proper drive, the Pathfinder sits. The neighbours know I've got exhaust especially at 5:30am when I leave for work.
I crawl out as slow as I can as I actually like my neighbours.
I don't like the factory Y pipe, and I do not want the Magnaflow on the pathfinder. My exhaust seems ok right now, but I want what should have come from the factory on the R51 which is the same design and what I have on my R50 Pathfinder- a 2 in and 1 out muffler configuration. It just makes sense that this is how it should have been, but we have what looks like a win for the accountant and a loss for the engineer with the final design for the R51. I'm sympathetic to the Engineer. I don't like this Y pipe performance loss/cost savings compromise.
The V8 Pathfinder has the right muffler with a 2 in and 1 out design. Has anyone taken that factory OE muffler to a shop and had them modify the piping so it fits the V6?
Or, has anyone taken a Factory or lesser quality Walker Quiet-FlowSS aftermarket Titan or Armada muffler to a shop and had them modify that to fit? They're also a dual in single out. Rockauto shows 0 options for V8 pathfinder mufflers, and in checking Walker's site, they don't list a muffler for the V8 pathfinder.
I looked at the R50 Walker muffler but the piping is smaller on it than the R51 so not a good candidate I don't think. I'm on my second Walker on the R50 and I'm content with it, it lasts about 6 years for me at a fair cost. I'd rather a bigger piped muffler for better flow (I know the quiet ones are still restrictive) so am looking at the V8 Path, Titan, and Armada options as candidate for a customised solution for the V6 pathfinder, for when the time eventually comes that my original muffler needs replacing.
