bama16 Posted December 2, 2007 Share Posted December 2, 2007 anyone know where to get a DP flange for a stock turbo? i searched the web but can't find anything. i'm gonna build my own system...choose the mufflers i want, install 3" high flow cat...and shave about a grand off the cost. i've seen a couple dif DP designs..one had 2 holes..one 3" for the exhaust...and a smaller for the wastegate that met back up with the DP...the others just have that wide opening and it all flows in together...either one i can build...the 2 hole would be easiest...but i just need to find one. mandrel bendsm and y pipe are easy to get...and i can weld...so i figure why not! thanks all Link to comment Share on other sites More sharing options...

mickeyd2005 Posted December 2, 2007 Share Posted December 2, 2007 I wouldn't make a custom downpipe unless you were going to use a external wastegate. It's kind of cumbersome to build a bellmouth or weld an extra pipe for the wastegate. It would be cheaper to just buy a cheap downpipe and modify it. Some of the cheap ones have fitment issues but it would be cheaper to fix the fitment issues than to build one from scratch. If you really want one, here's one. I can't vouch for its quality such as hole placement. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=110076829355&ru=http%3A%2F%2Fmotors.search.ebay.com%3A80%2F%3Ffrom%3DR40%26satitle%3D110076829355%26fvi%3D1 Link to comment Share on other sites More sharing options...
fweasel Posted December 2, 2007 Share Posted December 2, 2007 didn't say it had to be yours. Plenty of stock parts leaning up in the corners of garages. ignore him, he'll go away. Link to comment Share on other sites More sharing options...
PhilT Posted December 2, 2007 Share Posted December 2, 2007 Make one. Small piece of 12mm stainless plate, a drill and a file, that's all you need along with an hour of your time. Double Award Winning Legacy GT Wagon Link to comment Share on other sites More sharing options...
bama16 Posted December 2, 2007 Author Share Posted December 2, 2007 how cheap is cheap? are you talkin about one of the ebay ones? i saw a couple in like the 170 range...where for an hour of my time i could make one...weld in bungs for all the stock sensors wouldn't be a problem. would this cause any problem with the warranty?

bama16 Posted December 2, 2007 Author Share Posted December 2, 2007 whoops....i (edit)wouldn't go external WG....but i'm just lookin to make things more efficient : )....that little car in my avatar makes 400rw and weighs in at 2300lbs...thats the toy...this is a solid DD so i'm not goin crazy : ) Link to comment Share on other sites More sharing options...
mickeyd2005 Posted December 2, 2007 Share Posted December 2, 2007 If you can make a custom Subaru downpipe (either divorced or bellmouth) in an hour then you are a master fabricator. edit: didn't see your comment about ewg. yeah, I would make a custom downpipe then.

bama16 Posted December 2, 2007 Author Share Posted December 2, 2007 i've made flanges before goin off the gasket...but for 30 bux it'd be worth havin a nice one already made. that alone would cover the correct size bits id need. Link to comment Share on other sites More sharing options...
bama16 Posted December 2, 2007 Author Share Posted December 2, 2007 i'm not a master fabricator...but there's not much that really limits me expcept for the # off $$$$ tools i have in the garage : ) lookin at the stock system...it's tiny...i've seen 20rwhp gains with just a DP alone in certain applications,,,get rid of some of those sharp small bends in the back...i just see larger piping in turbo applications improve flow..and increase hp...all i'm lookin to do here without goin crazy...just want it to be efficient. edit above post ***wouldn't go external Link to comment Share on other sites More sharing options...
bugblatterbeast Posted December 3, 2007 Share Posted December 3, 2007 Make one. Small piece of 12mm stainless plate, a drill and a file, that's all you need along with an hour of your time. there's a guy in Burlington who sells them for $30CAN. I'll see if I can dig up his contact. I bought one from him about 2 years ago. unfortunately he doesn't sell spherical seat flanges... if anyone knows where I can find one, please chime in Link to comment Share on other sites More sharing options...

PeterJMC Posted December 5, 2007 Share Posted December 5, 2007 Maybe you could PM some of the vendors to see if you can source one of their flanges for a low price. Link to comment Share on other sites More sharing options...

PeterJMC Posted December 5, 2007 Share Posted December 5, 2007 When do you plan on starting your DP project? I don't think anyone has actually made their own DP other than getting a shop to custom fabricate one for turbo setups. Keep us posted on how your project turns out. After finding out that you can easily purchase flanges... I wouldn't mind taking a crack at making my own up-pipe! Link to comment Share on other sites More sharing options...
BoxerGT2.5 Posted December 5, 2007 Share Posted December 5, 2007 thanks all...i did a search on here but anything...a search with downpipein the serach field yields hundreds of threads on downpipes...i It's a bitch ain't it? Good thing your not doing an UP, you'd weed thru 200 "Which UP is best?", "Flex or no-flex", "Do I have a cat?", "OMG I have a phucking CEL now" threads. OBAMA......One Big Ass Mistake America!
