Adding Uel Headers to an 09 2.5i Legacy?

[th3gl1tch]

So I have an 09 legacy with an ej253 2.5i. I've only recently been researching subies and I love them. But my car doesn't have that rumble. Through research I've found that I can fit some uels on there but would have to get a whole new exhaust system. Others have said it should fit right in. I want to do this right the first way and not mess it up.

 

So I guess the questions are

1. What size UELs would fit my engine or how do I find that info?

2. Do I need to mess with the MAP sensor or any other components?

 

Be kind I'm still new to this. just trying to gain some knowledge. thanks to any and all who help.

I have put UEL stainless headers on my 00 & 01 obw. They claimed to be for an impreza but bolted right on an obw.  They are very close to the oil filter but I see no heat damage on the filter so I think thats ok. On my 01, that is the only odd thing about the fit. The 00 has the same issue with being close to the oil filter but it also has a slight rattle when the body flexes. I have had them on the 01 over a year now and I just last month put the set on the 00.After a while I will remove the 00 ones  and see about bending whatever they are hitting.  Do they "rumble" ? can't say that I've noticed but what they really do is scavenge the exhaust and make them run stronger. No problems  with the computer system or anything else after the change.    As far as an 09 ??? start on ebay and go from there. Seems in my year group 00-04 they just don't list any for obw but by luck I had a set available to try that were made for an impreza, and they fit just fine. (thats the set on the 01) . If they are available in your year then order a set for an impreza ... treat them gently ,remove your old Y pipe and compare them... if it looks like they might fit then try ... if not box them up and send them back, OR.... find a teenager with an impreza and sell them to him.    Good Luck and welcome to the world of subarus!
