redoing my exhaust, what options?
so Im lookin to change up my exhaust again on my 93 legacy l. right now Im running a dynomax muffler and it sounds good, not to loud but a good rumble.
currently the mid pipe and axleback are starting to really rust out and I figure I want to change them both out. from what I found from searching the impreza exhaust fit but need to be extended. does this aply to all the impreza exhaust?
specifically this one
http://www.amazon.com/OBX-Type-H-Exhaus ... 128&sr=8-2
for the money this seems like a nice system, everyone seems to say the quality is great and sound is perfect. plus I wouldent mind a little more power
so will it fit? will I hurt performance at all going to a larger pipe diameiter? also what other options do I have?

Not sure about an RS exhaust fitting but all the WRX systems are nearly a direct fit aside from needing abourt10 inches of extension in the middle.

So I won't pick up any more power? So is it realy worth spending the extra money on a stainless set up as this one?
My local shop quoted me 150 for 2.25 galvenised piping from the headers all the way back to my dynomax muffler. Does this sound reasonable? Will I notice any increase in power going to the slightly bigger piping diamiter?

Considering where you live (smog) your best bet is to get a nice cheap (cat) and muffler off a subaru forum, www.Clubwrx.net , www.nasioc.com are just a few. Then go to your local shop and have them use some galvinised pipe ( unless your going for looks then get the stainless offline) Otherwise your going to save some cash, and who dosent want that. As far as power you might gain something, but that realy depends more on the rest of your system, DP, Headers, UP, ext. Are you running a vf11? if so youll notice it more down low. If you have something like a TD04 youll notice it more up top.

Ok so your not truboed sorry. lol. Yeah just get the galvinised you wont gain much sorry guy. YOU WANT POWER YOU WANT BOOST>>>>>>>>>
god I wish I had an ss lol
eventually I would like to turbo my legacy but for now Im focusing on building up my suspention. auto x is coming up this summer and I want this thing to run like its on rails.
but anyways Im probablpy just gona get a 2.25 pipe welded up at my local shop and use my exsisting muffler. I mean with my exsisting muffler it already sounds good and it complements the intake nicely.
will I niotice any performance increase going to the bigger piping?

Agreed. Don't forget that an NA car needs back pressure, so if you go too big you'll lose power, a turbo car has built in back pressure from the turbo so it doesn't really need any from the exhaust. 3" might not be too big, but I think 2.5 or probably even 2.25 is plenty bigSubiePrice88 wrote:Stock NA is 2" so 2.25" will be plenty for a N/A. Plus that saves you more $$$ for suspension so you can smash at AutoX
3" on a NA car is over kill!
And my friend with a 2000 2.5RS told me the exhausts are interchangeable between the RS and the Legacy, but I don't know 100%. He did say that you do have to extend an 02+ Impreza exhaust to fit the GC, just like you do for a Legacy, but don't quote me on that. You can look at www.rs25.com for some info on that
One thing I'd be careful about if you go that route though, is I noticed the catback pipe can come straight off the midpipe without hitting anything on an RS, but it cannot on a Legacy.
The OBX exhaust you posted looks like it bends down though right at the flange so it may work fine. But it says 98-05, which is weird for several reasons...So again check about the extension thing if you do that.
On NASIOC, the guys there run 2.25" for maximum performance. They say 2.5" is too big for the NA engine and you'll lose bottom end if you go 2.5" or bigger. But I don't remember right now if that's for a 2.0L engine. (Maybe this post wasn't so helpful after all...) You might want to check it out on NASIOC.
