    Exhaust question

    The standard exhaust on a Coupe turbo is 2.25" in Diameter right?

    With this in mind how much power gain would you seriously expect from say a scorpion exhaust system that is also 2.25" in diameter?

    Would you genuinely get much power gain? Or would it just sound better?

    Yes 2.25" is standard on the turbos.

    What exhaust system would you be putting on?... precat decat? sports cat? backbox? Resonator box? etc will all depend on sound and performance.

    Precat decat would deffinetely gain power. and a de-cat/sports cat would also gain power.

    But why not go for a 2.5" system? cant see it being much more expensive, plus will help if you decide to go for bigger power.

    Coz there are several parts up in different areas at the moment from a scorpion exhaust but it's all 2.25", but coz it's second hand it's cheap! lmao.

    I have found in various parts most of a whole system. Can you mate up 2.5" to 2.25" ok though? Coz if so then I have seen a precat decat for sale which is 2.5, so could do that and follow it with 2.25" for now and upgrade as and when I see things come available or when I can afford a decent new system etc.

    Well a decent 2.5" custom exhaust system from turbo back can be had for as little as £500.

    But no, you cant match up a 2.5" precat to a 2.25 system without a trip to the exhaust place to get it modified im afraid.

    Hmmmm, ok, will see what I can get sorted and go from there.

    Cheers for the info. If I see a decent 2.5" system about and I have the cash then I will prob go for it, but depends on timing really. lol.

    Make, cost, miles done etc? I assume this will join up to the standard cat on the coupe right?
