Emilio Posted September 21, 2008 Share Posted September 21, 2008 Hello Guys: I have a 05 legacy gt 2.5 Mt with the AP V2 and I want to go to stage 2. I have been researching some posts but I did not find the answer. I am thinking to buy Perrin Up and Perrin Dp cat, or Invidia DP Cat and keep the OEM UP. I live in Texas and I am concern about passing the state vehicle inspection. Also I do not know what parts deliver more performance and durability. Thank you Emilio Link to comment Share on other sites More sharing options...
caramall2 Posted September 21, 2008 Share Posted September 21, 2008 Lots of posts out there. DP: I have a Cobb with a high performance cat...so if you're concerned about emmissions, maybe that's a good one for you. UP: Definitely get rid of the stock UP (it has a cat in it, not to smart just before the turbo) and get a catless aftermarket. After battling leaks, I like a flex UP. I have an integrated one with headers, but seems like some like the Grimmspeed and TurboXS uppipes. There are various non-flex ones too (e.g. Cobb makes one). Speaking of that, if you're interested in my Cobb UP (it's solid, not flex though) let me know now that I have my headers installed. Link to comment Share on other sites More sharing options...

AWDxBOOST Posted September 22, 2008 Share Posted September 22, 2008 get a flex joint in the uppipe, trust me its way easier to put in and somewhat less likely to leak Link to comment Share on other sites More sharing options...
