I have a contact through work who says they'll make me a replacement exhaust (from the cat back). The guys done this before, all I have to do is supply the drawing to work from and boxes. Off my own back I've also sourced the tube.
I only really want to see performance increase through increased airflow via the smother inner wall of the pipe therefore I've opted for a 50mm Grade 304 S/Steel Tube which is only marginally larger in diameter to the standard fit.
Can anyone recommend what boxes to fit which won't sound like a fat sl*g after a curry? Also any ideas where I may find drawing to work from or is it just a case of taking off the original and saying 'copy'?
any info anyone can offer would be great,
