MY08 VR muffler swap

Hey guys, I've recently got a 2008 VR Lancer sedan as my first car and I've picked up a twin exit muffler that seems to be from a 2009 ralliart. The things that go into the rubber hangers are not the same as my stock muffler so I know it'll take a bit of work but I was wondering if it'll need a tune or something once the twin exit muffler is on or if it'll be fine. This is my first time working on something like this so any tips would also be appreciated. Thanks in advance.

Generally speaking, you can change an entire exhaust system on a production car and it will be able to adjust enough to suit.

All cars nowadays have an oxygen sensor in the exhaust to make sure the car is injecting the right amount of fuel. If the sensor detects too little fuel is being burnt, it will tell the car to add more, and vice versa. There is about a 8-10% range of adjustability for more fuel or for less fuel, so assuming your entire exhaust changing the fueling by less than 8-10% (hint, a full custom exhaust system will be at most like 5%), you'll be fine.
