[HTi]Johnson Posted July 28, 2005 Share Posted July 28, 2005 Hey all. I made this downpipe...what do you think...I might be able to make more Oh yeah, I didn't bend the tube...I wish I could, it's too thin guage for the machines I have access to, But I had a muffler shop do the bending, I did the rest.

[HTi]Johnson Posted July 28, 2005 Author Share Posted July 28, 2005 I'll get back to you about making you one...I have to work out the transistion from the new downpipe to the old mid-pipe. But still leave the option for the new mid pipe. I can tell you that the DP wouldn't cost much...it cost me $40 to have it bent up. I could probably make them around $60-$75. Let me look into it. Oh yeah guys, these are racing downpipes...yeah racing.... Link to comment Share on other sites More sharing options...
oddcomp Posted July 28, 2005 Share Posted July 28, 2005 its tacky but works well i used 2" id flex pipe stuff to join my better than stock downpipe to my other section of exhaust Link to comment Share on other sites More sharing options...
JWX Posted July 28, 2005 Share Posted July 28, 2005 I think the wastegate pipe should be bigger, and a bit longer Link to comment Share on other sites More sharing options...
carfreak85 Posted July 28, 2005 Share Posted July 28, 2005 For that price I would be interested! Link to comment Share on other sites More sharing options...
Caboobaroo Posted July 28, 2005 Share Posted July 28, 2005 I think the wastegate pipe should be bigger, and a bit longer Yeah if you could make the wastegate line longer like down to the bottom bend, then it would be a lot more efficiant. Looks god none the less though! Too bad I have a TD04 now... Link to comment Share on other sites More sharing options...
DrKrazy Posted July 28, 2005 Share Posted July 28, 2005 Aye for that price you can put me down for one too! Looks pretty good, and way better than stock. Good Job...and do keep me in mind if you do start making them. Link to comment Share on other sites More sharing options...
carfreak85 Posted July 29, 2005 Share Posted July 29, 2005 I'm thinking that a bell mouth for merging the wastegate might be the best solution. Even if the wastegate pipe is longer, all you're doing is moving the turbulence further down the exhaust system. The bell mouth is the same design the Cobb tuning uses on their downpipes.

[HTi]Johnson Posted July 29, 2005 Author Share Posted July 29, 2005 do you have a pic of the bellmouth system? Link to comment Share on other sites More sharing options...
carfreak85 Posted July 29, 2005 Share Posted July 29, 2005 These pics doesn't help much, but you get the idea: Link to comment Share on other sites More sharing options...
Subieguy Posted July 29, 2005 Share Posted July 29, 2005 What really is being gained with this design of downpipe? I am curious. I could make one myself. I work at a exhaust shop. Maybe next time I come across a turbo Subie I might want to do this. Don't have one right now. Just sold my 89 GL10 Wagon for $1700.00. I thought that was a good deal considering I got the car for free less than a year ago. Link to comment Share on other sites More sharing options...
TurboSPFI Posted July 29, 2005 Share Posted July 29, 2005 Sounds pretty appealing to me Link to comment Share on other sites More sharing options...
nkx Posted July 29, 2005 Share Posted July 29, 2005 I think the wastegate pipe should be bigger, and a bit longer right on my train of thought! it should join up with the rest of the exhaust farther downstream. Link to comment Share on other sites More sharing options...
[HTi]Johnson Posted July 29, 2005 Author Share Posted July 29, 2005 this downpipe is 2.25" od that's a significant increase from the what 1.5" I.D. of the old exahust. THe stock pipe looks big, but it is a pipe with a heat shield. This downpipe provides more flow than stock...considering how the stock one has a huge catylitic convertor on it.

critical_max Posted July 29, 2005 Share Posted July 29, 2005 That's awesome, can't wait to see it on your wagon! My exhaust needs to be replaced from the outlet ports back, so you could consider me a potential customer too Link to comment Share on other sites More sharing options...
Yorick Posted July 29, 2005 Share Posted July 29, 2005 If you could do this with a flange for a TD04 turbo, I'd definitely be interested. -Ian Link to comment Share on other sites More sharing options...
carfreak85 Posted July 30, 2005 Share Posted July 30, 2005 If you could do this with a flange for a TD04 turbo, I'd definitely be interested. -Ian I'll second that since I'm planning on doing that in the near future. Maybe I could get one of each... Link to comment Share on other sites More sharing options...
[HTi]Johnson Posted July 30, 2005 Author Share Posted July 30, 2005 could someone send me a template or possibly a flange for a td04? Link to comment Share on other sites More sharing options...

Hey, I have a bellmouth downpipe on my GL-10 and it works exceptionally well. It funnels down into a 2.25"pipe that goes all the way back to the muffler. I am considering upgrading the downpipe to 2.5" dia. when I get back. Here it is in my list of mods from way back: http://www.ultimatesubaru.org/forum/showthread.php?t=24110&page=3&pp=10 Link to comment Share on other sites More sharing options...
