What I'm shooting for is a full 3'' turbo back exhaust for my STi. Something along the lines of either a Helix or Cobb downpipe (with cat) and of course a cat-back exhaust.
I'm digging the Borla XR-1 as I understand its not too obnoxious, and looks somewhat like a stock STi exhaust. My concern is that there is an adapter used to mate the Borla exhaust to a 3'' downpipe. I have yet to get a full description of what this adapter really is.
Does the Borla midpipe technically have a 2.5'' flange that through some masterful gasketry and flange extension piece is made to bolt to a 3'' down pipe (which would present a 2.5'' kink in the exhaust, maybe, no bueno)? Or, is this an intermediate section of pipe (either with a 2.5'' or 3'' end) that through a shortened midpipe, mates the downpipe and midpipe?
Could you post a picture of this adapter?
Thanks for your time.
We do not have a picture of it, but basically what it is, is that there is is a 2.5" section on the part that mates to the downpipe, that is the only part of the exhaust that is 2.5" the rest is a full 3" exhaust.
Basically, u can mount the exhaust the way it is to the downpipe, however it is not a flat flange. You can get a flat flange made @ any exhaust shop, it cost me $40 to have mine done.
When you get a flat flange made up you also need to ask for a 3" slip joint which is what you will need to mate the catback onto the downpipe perfectly w/o any leaking issues.
