ive had japspeed decat up-pipe, decat 3 inch down pipe and a decat 2 and a half inch centre section fitted today along with a racedynamix remap, the problems im having are that the gaskets that have been supplied are not very good and are blowing, ive got genuine metal subaru gaskets now for both ends of the up-pipe and turbo to down pipe, What is the best way of connecting the 3inch down pipe to the 2 1/2 centre section would it be a 3inch gasket and a 2 1/2 inch gasket sandwiched together as that is were the worst blow is please help, apart from these im happy with the remap.

 

Did you have them fitted at a garage?
