    Catalytic question

    On my early coupe i am expecting to find a one piece cat. I am soon to buy a Milltek pre cat. My question is this... To save having welding done to fit the pre cat, would a standard GSI cat bolted up to the Milltek pre cat fit onto my cat back system?
    Hope somebody can help, i had a quick search with no concrete answer.
    Thanks

    indeed it will as i sold my old cat to a lad on here who has a coupe turbo! i had the cat back on the standard cat for a long while so it fits! its the easiest way to do it if you can come across one!

    Yeah it was me thought the miltek pre cat pipe only fits the miltek sports centre cat as the bore is alot bigger, so it would not fit to a standard gsi centre section, don't hold me to that though as that is what was said buy a tuner. I bought a magnex one for cheap as they have closed down their business a few weeks ago.
