Yamba6 Posted November 24, 2014 Share Posted November 24, 2014 I own a 2005 Legacy GT. In the summer I purchased a Borla Cat back exhaust. When I purchase the exhaust I asked for them to send me a gasket which they did. They sent me a flat gasket like you'd have for a manifold or header. When I installed this it seemed as if it required a round bubbled/thicker gasket. Doing some research its as if a N/A gasket was originally on my cars exhaust (The bubbled type) Between the cat and the mid pipe. When doing the cat back it now seems as if the flat gasket is not sealing properly to a flanged end. Does anyone know which gasket I'm supposed to use. This is what they say the OEM N/A would be, but what I feel I should have with my Turbo. (This seems like what we had to chizzle off the cat) http://www.carid.com/ic/bosal/exhaust-parts/256-099_3.jpg This is what they sent me. http://www.jscspeed.com/images/products/4c4db0b4dfcf02cc.jpg http://legacygt.com/forums/data:image/jpeg;base64,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 Link to comment Share on other sites More sharing options...

That is my understanding but everywhere I look says its for the N/A. Not sure why mine would have that version if I have the turbo. What would you need for one?

MrTris Posted November 24, 2014 Share Posted November 24, 2014 Where doe the gasket go? End of DP? If yes, then you need the donut gasket. Based on your descriptions, I'm nearly positive that's what you're looking for. Link to comment Share on other sites More sharing options...
TakmaN Posted November 24, 2014 Share Posted November 24, 2014 If you're mating the exhaust to the stock DP then you would need a donut gasket, not a flat one. If you're using an aftermarket 3" DP and a 2.5" exhaust, you'll need an adapter like one that Grimmspeed sells along with a donut and flat gasket.

Yamba6 Posted November 25, 2014 Author Share Posted November 25, 2014 It is between the Cat and the Mid pipe, not down pipe. I can not put a high flow in or I would. Issues with putting more power/tune that will possibly cause problems with my engine due to internal damage with a leak down. So I have a stock down pipe, stock cat, cat goes to borla exhaust which I was told bolted right up find to the cat. When removing the original midpipe and back, we had to chisel away an old gasket which did not seem flat. I wish I had picture of this at the time but don't. It seemed as if the donut should have gone there. Link to comment Share on other sites More sharing options...
Yamba6 Posted November 25, 2014 Author Share Posted November 25, 2014 This is the best I can find for a picture showing a resemblance to the end I'm speaking of on the cat. http://wcaperformance.com/images/T99354461.jpg Link to comment Share on other sites More sharing options...
