YouAreABus Posted July 7, 2009 Share Posted July 7, 2009 I thought I was doing good by buying a quality uppipe from Perrin, but after a couple hundred dollars in gaskets and trying every different install procedure I could find on the web, I still have a leak at the lower uppipe connection. I'm going to buy a different pipe and I think one with a flex section will get the flanges flat and help it seal properly, but I'm not sure who's to buy. I don't want to spend a huge amount of money so I have it narrowed down to three. DC Sports, GrimmSpeed, or Turbo XS. I'm not really swayed by the fact that some come with studs and gaskets and some don't becasue I'm going to use Remflex gaskets and $5 in exhaust studs is no big deal. I'd like to hear peoples experence with these pipes good or bad. I like that the Turbo XS and GrimmSpeed have smaller flex sections located in a straight part of the pipe and that the flex is closer the the problematic end, but how is the quality between the three when it comes to type of metal used, flange thickness and build quality?

biz77 Posted July 7, 2009 Share Posted July 7, 2009 The Greddy seems promising for the money. Link to comment Share on other sites More sharing options...

Mega Users LieutenantDan Posted July 7, 2009 Mega Users Share Posted July 7, 2009 Used STi is the way I went and the way to go IMO Stock heatshields, a flex section, and OEM fitment and quality Link to comment Share on other sites More sharing options...
Darkness of Death Posted July 7, 2009 Share Posted July 7, 2009 or you can go 07+ LGT as they are catless as well i went with grimmspeed coated myself Link to comment Share on other sites More sharing options...
YouAreABus Posted July 8, 2009 Author Share Posted July 8, 2009 The Greddy doesn't have a flex and I don't want to be in the same boat I'm in now. I had thought about the STi or the '07+ LGT but they don't seem to be as readily available because there is really no reason the upgrade them, right?

hybridandy Posted July 8, 2009 Share Posted July 8, 2009 Grimmspeed coated uppipe and I'm using their gaskets as well. Nice thick flanges and no leaks so I've been very happy with it so far. Link to comment Share on other sites More sharing options...

Darkness of Death Posted July 8, 2009 Share Posted July 8, 2009 it's good to have a flex section in the uppipe. makes the install easier (at least) compared to one without a flex section Link to comment Share on other sites More sharing options...
YouAreABus Posted July 8, 2009 Author Share Posted July 8, 2009 I've had both styles on two different subies and it's not that the installation is easier, but alot of people have trouble getting the lower connection at the exhaust manifold to seal and a flex section seem to help with the fit/seal.

Mega Users LieutenantDan Posted July 8, 2009 Mega Users Share Posted July 8, 2009 I put up a Want to Buy thread for an STi uppipe and got a response within the same day. A quick search brought up a couple recent WTB threads. http://legacygt.com/forums/search.php?searchid=6287807 Link to comment Share on other sites More sharing options...

YouAreABus Posted July 9, 2009 Author Share Posted July 9, 2009 There's actually a local guy who has one for sale, I'm just waiting for him to reply to my PM. If I can get and STi pipe for a good price, maybe I can spring for the GrimmSpeed mid section too. What kind of performance increase potential if there with the mid pipe (between the manifolds)?

TRSCobra Posted July 12, 2009 Share Posted July 12, 2009 I got my TurboXS for ~$150 shipped from ebay and I have no complaints. I used OEM gaskets and it hasn't leaked with over 6K miles of use. It even came with the resistor for the EGT delete. Link to comment Share on other sites More sharing options...

I'm 99% sure that all '04-'09 Subaru turbo applications use the same manifold/uppipe setup. Link to comment Share on other sites More sharing options...
