2004 Liberty GT BP EJ20 Header Options

Postby lberty.len » Wed Jan 16, 2019 9:27 am


I bought a 04 Liberty GT BP Wagon for a very good price (comes with extend warranty so i couldn't say no).

My question is what UEL headers will fit my car? Can I do a direct swap from a EJ20 WRX, Forester, Liberty GT 2.5L possibly?

I want the Subaru rumble. I understand that these run a twin scroll turbo so I will be changing that out too, possibly another WRX part I could bring over?

I am hoping I can find a WRX, liberty etc from a wrecker and bring the parts almost directly across.

If all this has been answered before please excuse me! I did try and dig trough google to find something.

Thanks heaps guys!

The thing is they’re decent headers up to eg 250atw!

If you must change just for the noise, you’ll need headers & uppipe, turbo, turbo bracket, dump and 3” mid and matching muffs.

The classic wrx sound, I guess it depends how loud you want.

Generally you can start from the muffs and work your way back, opening up ad you go, but bear in mind changing the exhaust back pressures changes your tune, so get logging & lv for safety and sanity.
