2017 TRD Pro Performance Exhaust System

I was on Toyota's web site today with a buddy who is interested in one. On the "build your Tacoma" section there is an option for a TRD Pro performance exhaust system. The description says "The TRD Pro exhaust gives your engine greater power with a less restrictive path, while bellowing out a deep, throaty tone." I was just curious if any one had any Idea what it looked like and how they rerouted it to give it a "less restrictive path". Sorry if this has already been brought up. I did a quick search and didn't turn anything up.

Do you know the diameter of the piping?

 

No I don't. I am guessing that it's a little bigger by maybe a half inch, but I'm not sure.

 

I wouldn't think that the diameter of the piping would change but rather utilizing a smaller, less restrictive muffler. That's my guess though.

 

I was waiting for the TRD cat back but when they almost doubled their price I lost interest.

WOW! $850 for a cat back system. I think I will find something else. Thanks for the link.

 

I'm curious as to the diameter of the exhaust also. Only reason I ask is to see if it's necessary to get an aftermarket exhaust
