2005legacy2.5i Posted July 20, 2010 Share Posted July 20, 2010 Hello all I have tried to search this but have been overwhelmed with all of the results. My question is can i put UEL headers (like borla replicas) without replacing the CAT on it, It's a 2005 legacy 2.5i 5MT. It was manufactured in 12/04.

CDN 2.5i Posted July 21, 2010 Share Posted July 21, 2010 If your stock header looks like this: http://i684.photobucket.com/albums/vv205/andrewolive/CIMG3762.jpg then yes, it will bolt on. Link to comment Share on other sites More sharing options...
2005legacy2.5i Posted July 21, 2010 Author Share Posted July 21, 2010 thank you! so if they look like that I don't have to replace the cat just bolt on borla UEL headers? thanks Link to comment Share on other sites More sharing options...

Malt Beverage Posted July 23, 2010 Share Posted July 23, 2010 Is the other header type the ones that wrap around the oil filter? Those make for a painful oil change. Link to comment Share on other sites More sharing options...

2005legacy2.5i Posted July 23, 2010 Author Share Posted July 23, 2010 Thanks for the help everyone.

OhBe1 Posted July 23, 2010 Share Posted July 23, 2010 Is the other header type the ones that wrap around the oil filter? Those make for a painful oil change. They do. I think they started in '06, and added a few torques. And complicated fitting a skid plate. 06LOB2.5i MT, JDMRSB, GYTTs, HPS, LGT Mufflers & Leather Wheel, SubiMomo Knob, Inalfa Moonroof, Clutch Switch Bypass, DeDRLd, DeChimed, & Straight Headrest.

GEE-OTTO Posted July 26, 2010 Share Posted July 26, 2010 To the OP if you get UEL's and not Borlas get the higher cost eBay ones trust me you dont want to chop and reweld (as I have done on two sets of cheap-O's) also wrap them to guard against the "sewing machine" sound. And don't use the supplied gaskets get OEM Link to comment Share on other sites More sharing options...
CCSubaru Posted July 26, 2010 Share Posted July 26, 2010 Wait so I can put UEL header on my 08 2.5i now? Link to comment Share on other sites More sharing options...
GEE-OTTO Posted July 26, 2010 Share Posted July 26, 2010 Wait so I can put UEL header on my 08 2.5i now? Yeah but you have to extend the sensor plugs and change the exhaust or have a set modded to fit your stock mid pipe Link to comment Share on other sites More sharing options...
CCSubaru Posted July 26, 2010 Share Posted July 26, 2010 So i'd have to buy like a legacy gt cat back exhaust and then extend the sensors too? Link to comment Share on other sites More sharing options...

No you need to go to this link and scroll down: http://legacygt.com/forums/showthread.php/2-5-lgt-header-mod-fit-2-5i-104369p12.html?highlight=LGT However chances are you wont be able to find a guy to weld cast iron where you live soooooooo you can do the exact same mod as pictured above only you need to use a manifold like this with a cat : http://i144.photobucket.com/albums/r182/GEE-OTTO/42af9773-1.jpg Link to comment Share on other sites More sharing options...

akline5 Posted July 27, 2010 Share Posted July 27, 2010 Pretty sure I saw you heading west on County Line when I was heading east... theres a bunch of N/A legacy's around here too though... Link to comment Share on other sites More sharing options...

sulk Posted July 28, 2010 Share Posted July 28, 2010 Will these do anything for you besides a cool rumble? I think they are supposed to increase torque/hp. But I don't think there have been any dynos on our NA legacies to confirm anything. (let alone almost any dynos for anything) Maybe if you look at results from imprezas with ej253, you may see something. I think people with imprezas may have ran more dynos then us. Also maybe, the 2.5RS guys may have something to confirm, theyve been around for a while. Link to comment Share on other sites More sharing options...
