kd5zmg Posted October 5, 2011 Share Posted October 5, 2011 I was wondering if this will work on my LGT: http://cgi.ebay.com/ebaymotors/OBX-SS304-EXHAUST-CATBACK-97-01-SUBARU-IMPREZA-2-5RS-/390352267051?pt=Motors_Car_Truck_Parts_Accessories&hash=item5ae2cee72b I was going to get this, but will have to wait until it is available again. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=170702771320&ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 Link to comment Share on other sites More sharing options...

kd5zmg Posted October 5, 2011 Author Share Posted October 5, 2011 what would the other year and model exhaust could I get? The second one says it's a direct fit. Link to comment Share on other sites More sharing options...
I Donated broknindarkagain Posted October 5, 2011 I Donated Share Posted October 5, 2011 The second one is long enough, but hangars are different. The only direct swap on your exhaust would be something SPECIFICALLY made for the Legacy -broknindarkagain My Current Project - Click Here COME AND TAKE IT "The only thing necessary for the triumph of evil is for good men to do nothing."

kd5zmg Posted October 16, 2011 Author Share Posted October 16, 2011 Since this CatBack is shorter, does anyone know if I just need to extend the secondary pipe or the pipe on the muffler side. On another note, I just got my coated header back from Cradin Industries in Boerne, TX. He said it's a Zirconia type coating. It looks like primer to me. http://carphotos.cardomain.com/ride_images/4/567/4449/38917224036_medium.jpg Link to comment Share on other sites More sharing options...

That should definitely help with exhaust flow. Link to comment Share on other sites More sharing options...
kd5zmg Posted October 16, 2011 Author Share Posted October 16, 2011 Can't wait to install the new header! I was going to do this cat back, but I was thinking, since the outlet is only 2.25" on this header, is there any benefit going 2.5" pipes? I am thinking not, but I am sure someone can school me on this. I will just find a different muffler to replace the stock one if there is no benefit to running 2.5" piping.

I Donated broknindarkagain Posted October 16, 2011 I Donated Share Posted October 16, 2011 Some will tell you that there is a benefit, but personally I don't think a N/A EJ engine moves nearly enough air to even gain a minor (if any) benefit. You might get a different sound out of it....but performance wise I don't think you would get much -broknindarkagain My Current Project - Click Here COME AND TAKE IT "The only thing necessary for the triumph of evil is for good men to do nothing."

Baddog Posted October 16, 2011 Share Posted October 16, 2011 Without internal work. Our wonderful N/A Subaru's will not gain much power. All sound, sadly. Link to comment Share on other sites More sharing options...
kd5zmg Posted October 16, 2011 Author Share Posted October 16, 2011 Ok, thank you for the response. I will just go with a different exhaust. Also, I didn't want to have a loud sound, just deep. On another note, the gaskets that came with this header looks thick, but I remember when I was working on my SR20 motor that I bought a nice copper one from Summit Racing. Should I do the same and get that or just some factory OE gaskets from the dealer. Autozone doesn't have our gaskets, exhaust nor flange. Link to comment Share on other sites More sharing options...
I Donated broknindarkagain Posted October 16, 2011 I Donated Share Posted October 16, 2011 You can use what came with the header or OEM....doesn't really matter. Gaskets are gaskets....unless you're talking about head gaskets -broknindarkagain My Current Project - Click Here COME AND TAKE IT "The only thing necessary for the triumph of evil is for good men to do nothing."

grovlet Posted October 17, 2011 Share Posted October 17, 2011 My suggestion: Take it to an exhaust shop (Not Midas/Meineke) and have them install the Header and build you a custom Cat-Back. That's what I did, and it was a total of $650 out the door... And that included heli-coiling all 6 Exhaust Studs, as they are guaranteed to break on the Header Install!! I went with 2.25" piping, High Flow Cat, and a High Flow Dynomax Muffler. There is definitely a gain in throttle response, and I swear by the 'Butt Dyno' a HP gain as well, but no definitive numbers to prove that.....

kd5zmg Posted October 18, 2011 Author Share Posted October 18, 2011 grovlet, do you have a video or sound clip... that would be way cool if you could post one up. Link to comment Share on other sites More sharing options...
Kennyfvholla Posted October 18, 2011 Share Posted October 18, 2011 and which dynomax muffler is it? that makes a huge difference in how it sounds and how loud it is Link to comment Share on other sites More sharing options...
grovlet Posted December 31, 2011 Share Posted December 31, 2011 Sorry just got back to this one...... Here's the clip I posted after install: Sound Clip I'm not sure exactly which Muffler it is, but it's one of the straight through high flow models.
