Check out Landspeed-DSM car he's running hood exit exhaust it look's badass. IMO I wouldn't do it unless your building a full race car. If you plan on driving it on the street a lot it will be super loud and annoying. Just my opinion.

Just curious if there would be any gains from doing that.
Yeah some people do run their pipes straight out the hood on here. I can't remember who right now but it's bad ass.

This was before everything was finished and trimmed to fit. But you get the idea. Oh yeah, street driven as well.

My plan is to run a fender exit exhaust, and a full exhaust for street driving. I'm going to be welding in a y pipe for my dump switch. Will be able to maintain regular city driving as well as drag racing with this setup. Just curious how others have done this.
Love the hood exit idea as well.

And cover your windshield in soot + collect rainwater.
Regarding soot, it's no more inconvenient than cleaning bugs off the windshield. For which science has graced us with methanol and squeegee technology.
Honestly the turbine is a pretty good muffler and compared to open DP under the car reflecting off a solid surface if may even be slightly quieter through the hood just radiating up and away.
Here's a few, let me know if you had anything in mind that would be more helpful:

Farther away for orientation..
Indeed, there are.. the shortest path to atmosphere is best on a turbo application. Ideally you would keep it as straight as possible, using a plain O2 housing flange and matching it to the turbine housing and weld a v-band on for both the turbine discharge and the wastegate. Then using an exhaust cone or concentric reducer:
Concentric Reducers - 304L Stainless - Butt-Weld Fittings - Ace Stainless Supply
To make a smooth transition out to as much as a full inch more in diameter for the downpipe.
You will greatly increase not only the efficiency of the turbo but your engines ability to breathe. Quicker spool for more power across the board, decreased drive pressure from the drop in backpressure will allow more overlap in your cam timing, raises knock threshold, greater whp/psi boost ratio, etc.
These are not just my opinions, these are fact
Thanks! The hood exit gets mixed reviews, most are positive and most of the negative are from non-car folks.
Sometimes made for funny/awkward moments like in april when I was wearing a shop shirt while wrenching when it was in a buddies shop for fab and a delivery guy was ripping on it as "### honda shit" thinking I was an employee. Let him go for a few minutes laughing with him before telling him I chose to do it for functionality not looks.. some epic backpedaling ensued.
Being nearly a foot taller and over 100lbs on the dude, he got pretty sheepish.
In use.. its not much if any louder than open downpipe exiting anywhere else. In addition to some soot it throws a decent flame from both gates and the big pipe under boost, as well as a light show when getting off the throttle
