Default General advice regarding exhaust

Hey everyone.

This may be the wrong place to post this but I'm not sure. Its been about 5 years since I've been on nasioc.

After the death of my 06 sti, I'm finally back in the game with an 09 red hatch

BUT I've already found out bad news. My exhaust is a knock off aluminum pipe and just found out there's a massive crack. So time to buy myself an early bday gift.

Here's where I hit my predicament. I want to do something with some good roar to it. So naturally I'm thinking invidia n1 cat back and an invidia catless downpipe. But looking at them online, I notice a few options (ie divorced wastegate with extra 02 bung or standard)

Not sure which too do or the difference honestly.

Any advice or recommendations of a different setup would be greatly appreciated!

Thanks all,

I have a catted Invidia dp divorced with extra bung on my 12 sedan. It's only a few bucks extra might as well get second bung for future purposes. I have the n1 race and love the sound of it.

The divorced or bellmouth is up to you and what you feel is right after you've read up on the topic. As for the extra O2 bung, get it if you plan on adding a wideband gauge. Even if you're not adding it right away, you can always keep the plug in the extra hole until you do.
