I have just had a tuned williams lump built and put into my Valver i am running the williams manifold and down pipe. I encountered an issue with my valver decat pipe.
1stly - the bore of the pipe is smaller than the williams.
2ndly the flanges, on the decat, at the end butt up at different angles. i.e on one end it lines up with my centtre section but the other does not line up with the flange on the downpipe?
think i'll need a custom pipe? has anyone else had this issue?
Thanks
