Installed and sounds great. Don't do straight pipe to mufflers. Need resonators in between to remove drone

I used a local muffler shop to install this, they did a good job though. My gas mileage has increased a good bit as well had an incremental increase in power and torque, it's hard, really, to gauge these without a dyno. It sounds great, everyone loves it. Most say it "sounds nothing like a 4Runner". My only complaint is the baffle within the muffler as this is a single entrance and exit muffler but the muffle itself has a dual chamber construction inside. Noise will be fixed with insulation.
