Easy bolt on. Sounds great. Some say its a bit too loud but i got used to it. I also paired it with a K&N CAI
 
TRD is somewhat mellow which I liked but the V6 doesn't sound good so it needed to be a bit quieter. I'll probably do Magnaflow on the next truck to keep the volume down. Really though it is up to your ears since neither add any usable power.

Actually been discussed trillions of times. Millions happend many years ago.

Makes me question 1 thing... What if magna made the trd exhaust?

Ok, 2 things

Why not just a muffler and save alot of money?

At least on my 2018, there is no straight section of pipe after the muffler to clamp an aftermarket muffler on to. I guess if you could get an aftermarket tailpipe it would be workable.

Huh?
Cut out old muffler, weld in new muffler
 
The pipe is thick enoug to weld, but the snout on the muffler is usually to thin to butt weld, unless you go with a Flowmaster. Butt welds would still be weak in such a situation. A new tail pipe would have a longer snout to allow a slip fit. So far, no one lists a replacement tail pipe for my truck.

Mbrp, just installed it today, sounds beautiful, it is loud, but why have a quiet truck. I have the k&n CAI, can’t beat the price of the mbrp, took me 30 minutes to take the stock exhaust off by myself, and 30 minutes to install the new one with a friends help.

I felt the same for yrs.... Then I got tired of drone when driving more than 20min on the highway. Plus it's more fun to #sleep
Back when the truck was new and weak, I wanted it to sound impressive.... Now, I realize no need for drone.

Hahaha respect. I’ll probably feel it, hopefully not for a while though. I want to enjoy it for a bit!
 
It would be interesting to tap into the exhaust in front of the muffler to hook up a manometer to measure the pressure in the stock exhaust system. Just because an exhaust is quiet doesn't necessarily mean that the flow rate is low. Look at Supertrapp mufflers for instance.

Flowbench will show how much it can flow. I'm sure it's more than an OEM engine can move.
