advice urgent I need the best magnaflow muffler for Tacoma 2016

I have the full cat back and it's been on there for almost 15,000 miles. Honestly it sounds like a Lexus V6 sports car, because that's kind of what the engine is. Especially in the higher RPM range. It's kind of funny in my opinion. Sounds like stock but louder and it can get very annoying on the highway running over 3,000-3,500 RPM going 75-80 MPH since the Taco seemingly can't use overdrive at all at those speeds with wind or an incline. Anyway, I like it for the most part and wouldn't go back.

It's an easy bolt on once you get the hangers off the stock system. The muffler included in the system has these specs if you're curious.

 

Yes. 4"
