To anyone who has the TRD exhaust.

I am curious to what the diameter of the tail pipe is. I just bought an aftermarket rear bumper cover that wraps around the tail pipe. The hole through the rear bumper is about 7 inches around. I would also appretiate any recommendations on other aftermarket exhaust . Thanks

 

I have never meaured it but it looks to be about 4 inches. And its kinda oval shaped

 

I have never measured it either, but i think its more like 2.5"/3" and yes it is more oval and the top comes out a little farther than the bottom.
