Extra weight and nonsense IMO. Run a 4" dump off the down pipe and 2.5" crush bent garbage back to a caddy muffler.

no room for a 4" on my car.. But I'm highly considering straights. I called a few shops this afternoon and only a handful said to run the X pipe.

I have no valuable data but x pipes are cool.

Any body else running strait pipes to rear?

Don't need it with twins. Short 3" DP and 3" dump. then run dual 2" crush bent piping all the way back after that.

As much as I wanted to go this route, I didn't. I already knew how it sounded with the X pipe so I just said screw it and used it. Not to mention it was an opportunity to use my new band saw and take a crack at pie cutting. It's a little crude but not bad for a first attempt.

No reason or benefit of doing a x or h pre or post twin turbo.
Post is fine if it's already in the cat back.

Agreed but the sound quality is way better with an X pipe. No popping/backfiring etc. It's a night and day difference.

Sound would be the only reason.

Clearly. Like I said earlier I only did it for the sound.

That's actually pretty neat and most of the piping made like that is in the engine bay covered in exhaust wrap anyways. I like it
