semsub Posted December 2, 2011 Share Posted December 2, 2011 Hi everyone) I want to buy this DP for my 05 gt 5eat and got some questions about it 1. Do I need some adapters ,tubes etc.. to fit it well with stock cbe? 2. What about noise? just louder boxer sound or some metallic (broken darth vader:lol:) sound with stock cbe? Because I heard some ebay DP with stock cbe on 2006 wrx , it sounds so ugly Thanks) Link to comment Share on other sites More sharing options...
iNVAR Posted December 5, 2011 Share Posted December 5, 2011 Yes, you'll need a 3"->2.5" adapter available here: http://www.fredbeansparts.com/index.php/3-inch-downpipe-to-2-5-inch-cat-back-exhaust-adaptor-1.html As for noise, you'll probably notice a deeper growl, slightly louder rumble, but not a huge increase in noise. Also, putting that DP on will REQUIRE a tune. ASAP. Link to comment Share on other sites More sharing options...
fahr_side Posted December 5, 2011 Share Posted December 5, 2011 The Invidia DP is pretty heavy (thick wall tube). I ran mine with the stock catback ('08 WRX) for a while and apart from some slight increase in spool sound it was unnoticeable. I'm sure from outside the car noone will be able to tell the difference. Obligatory '[URL="http://legacygt.com/forums/showthread.php/2008-gh8-238668.html?t=238668"]build thread[/URL]' Increased capacity to 2.7 liters, still turbo, but no longer need spark plugs.
