OK Guys,

 

First post here. I have a 99 Outback that I want to just semi get more power out of, nothing to extreme. I started with a KN Air Filter. So then I get thinking exhaust and low and behold a friend was willing to give me his stock wrx exhaust pieces. They included one of the cats, the longish midpipe, and the muffler. Well I thought that was all nice and dandy and today a friend of mine and I say lets swap it in, well we start by removing the stock exhaust and everything is fine for that until we go to mount up the new stuff. It doesn't mount up the friggin WRX is 2.25 and I think my stock stuff is 2.00. So my question is how in the hell do I get it to mount up? My friend and are not afraid to hack stuff, we just don't have a welder. So thanks for reading this essay.

It won't fit without fabricating an adapter pipe. If you have the axleback section, the midpipe and the second cat, you would make an adapter to go between your stock first cat and the wrx second cat. Besides the increase in diameter, the legacy is longer than a wrx.

 

Really it's not worth doing unless your current exhaust is bad. There won't be any gain in performance.

 

I actually bought an outback recently that somebody had put a wrx exhaust on. They made up an adapter, but it was a real hack job. I put it all back to stock.
