I want the boxer rumble and need to buy some UELs but I'm not sure if it's a direct bolt on from a Wrx to my 2.5rs
It's not a direct bolt on and would require cutting/welding and fab work. Your best bet is to buy a set of headers on Ebay, buyer beware that they will likely crack over time. http://www.ebay.com/sch/i.html?_fro...er.TRS0.G|1|0&_nkw=impreza+rs+header&_sacat=0 Mike
I installed the eBay version on my LGT just recently...Had a fair amount of fitment issues, but care runs/sounds better now. Only reason I did it though was that all three gaskets were leaking haha.
