who1981 Posted October 18, 2004 Share Posted October 18, 2004 The Header in my 94 Leg NA, just sprung its second leak, welded once, but it’s leaking again. I have seen other 94 Legacys with leaking headers in the same spot...wonder if it is a common defect (Cheesy headers?) Anyway, I want a higher performance header pipe (and perhaps a whole exhaust), and am wondering what to get??? I’ve heard the Borla 2.5L headers will work well. For about $250. WHAT is the advantage of this around-the-front-of-the-engine design? My current pipe is more like this: Is it just NA, and later models switched to the turbo type head pipe? Hmm. that Borla system is looking tempting (I haven’t spent any money on my car in a long time)... I’ll probably just have the “Cat-Back” built by a local exhaust shop (with good prices). Where I live we don’t have to pass emissions, so I can get creative. Link to comment Share on other sites More sharing options...
Legacy777 Posted October 18, 2004 Share Posted October 18, 2004 I'm not quite sure borla goes around the front of the engine. Maybe to tune exhaust pulses. The borla 2.5 header will bolt up, however you will need a different piping from the header back, since on the first gen legacies the first cat was in the header, and on the newer models, there's a separate pipe for both cats.

who1981 Posted October 18, 2004 Author Share Posted October 18, 2004 I just ordered the Borla header, after hearing a sound clip of it with a good cat-back system...hope it prefoms af nice as it sounds Now I just have to get the exhaust shop to fab me up a pipe. The rest of my exaust is in fine shape, including my awesome ebay mufler and 2nd stock cat...I wonder if they can, legally, make a cat-less through pipe to hook to my existing system? Think that'd work, just having the aft oem cat? I guess there would need to be an O2 sensor fitting in the "through pipe"... Link to comment Share on other sites More sharing options...
richierich Posted October 18, 2004 Share Posted October 18, 2004 You said you have gone through 2 headers being welded? Make sure that the exhaust mount on the transmission is not broken. Let us know how that new exhaust system works, looks very sweet!! And make sure that they mount it to the tranny in some way or it will flex and cause problems down the line.

who1981 Posted October 18, 2004 Author Share Posted October 18, 2004 My exhaust is mounted correctly, at all points, including the trany mount. The first time it cracked was partly my fault...for under estimating the size of a small tree I 4byed over , scraping the cat pipe a lil-bit. Though that only sent it over the edge, it was obvious that the header was week around where the two passenger side port-tubes come together... Also, do upgraded (polyurethane) exhaust hangers make much difference? For the better? Link to comment Share on other sites More sharing options...
