Here's a vid of my F with just the ISS DES in the first part of the video, then afterwards with the sikky headers and ISS DES together.

What is the area on that crush bend?
I just did a rear cat delete and fitted 63 mm straight pipes and the car felt much stronger than previous.
I am also thinking of replacing the two pipes that go to the rear silencers/mufflers with 63 mm pipes.
Will I still have the restriction of the crush axle bend?

There's a recent topic about a cheap solution to this, granted, your tips allow for it.
Check out this thread: https://www.clublexus.com/forums/is-...-20-bucks.html
I don't have a borla but i measured my tips and found the proper silencers for my exhaust. I hope you find it well.
