Most talk on TT has centred around whether removing the back fire screen does or doesnt give more power. I dont care much for that. I am however a little concerned the backfire screen in my 08 TE 450 may dislodge whilst changing a filter or introduce an unfiltered leak where it has the cutaway to fit onto the cage. I do use filter grease in this area. I run twin air filter p/no 157004 which i don't think has the backfire resistant foam. does anyone run this filter without the screen problem free? does anyone run without the screen with another filter? Has anyone had problems after they have removed the screen? Ps - i am not interested in more HP.
