Manual transmission? Give it a go...
Hey chris you are star!! Really appreciate all your replies mate. Im out of budget at the moment and trying not to break the bank so looking for this option. But appreciate all the info and ive been following you page as well, really awesome build mate.It will fit, but the exhaust will drone lke the dickens. The `16+ exhaust use a differemt flange for the muffler. Using the stock intermediate pipe won't work.
I've had similar setups with my 4eat XT....
`11 wrx (Sold for profit)
`16 wrx... (Dumped for a lost after modifying the mufflers)
`13 STi - (Mufflers and extra intermediate pipe in garage rafters
All of them using the a `11 WRX intermediate pipe, which has the same resonator like you posted. Due to the characteristics of the 4eat when driving, AND the second port on the muffler. It allows a negative pressure wave to develop back in the muffler creating havoc with sound to create our wonderful drone and booming. (Per speculation on my part.
But, the fix is shoving two Scotch Brite Stainless Steel scrubbers into the inside port of each muffler. (Not too far, just past the little lip so it doesn't pop back out under pressure, but not too far in to enter the chamber itself)
Even with the scrubbers, there is a totally tolerable off idle drone, and 1500rpm (40mph) drone. Not enough for the wife to complain, unless we are in rush hour traffic.
The STi/WRX exhaust IS the budget way to mod. But a lot more people are happier with Invidia Q300's And the Turbo XS, where it is single tip exhaust.
I have gone back to stock mufflers, but using WRX intermediate pipe. Stock mufflers are good for 300 hp.... Just do not sound all that spiffy. The intermediate pipe does bring a little boxer sound to the car. I haven't eliminated the resonator yet, as I am content with it...... For now.
Whichever direction you decide to take, definitely spray paint the back of the muffler black. It will blend in better and helps the tips "pop"....
Take note, blocking a port completely like the picture below is NOT advisable. It only exasperates the sound waves to that of a sledge hammer against your skull, not that I have experienced that.
Only can see if being over and looking straight in.

One link goes to Facebook, the other goes to my site that I run. There are no certificates on the second link because it’s not a secure link. It’s just a video file, you can download it or not but don’t expect it to be secure.
