A few problems.......
OK kids, please bear with me.........
Over the weekend I changed the downpipe on my 1994 WRX to an open neck 3" - 2.5" decat jobbie. I fired the car up today to see the difference and it sounded great but it was blowing from the gaskets. I called Roger Clark Motorsport and I'm getting some new gaskets in the morning.
However, I couldn't resist talking it for a quick rumble up the road. Before I changed the downpipe, I could hear the dump valve (standard) during spirited use and when changing gear around 3000 revs. Now, I cannot hear the dump valve at all and also the car only boosts to 0.75 bar whereas before it would go to just under 1 bar. The boost is made very gradually as well.
Would a blowing exhaust gasket cause this problem? The car was fine before the de-cat but now it makes less boost and doesn't go nearly as well as I thought it should.
Mods so far are decat centre and downpipe, ninja back box, walboro 255, induction kit.
Any ideas on what could have caused this would be greatly appreciated!!
