Removing silencers
« on: September 21, 2009, 10:13:05 am »
Morning guys

Thinking about removing the middle and rear silencers on my AGP. I've been driving around in my brothers A500 and love the sound it makes and would like my Abarth to sound sort of like this.
Do we think that removing bother silencers and having a straight through pipe would be to loud.

Your thoughts, opinions and advice as always please.

    Remove both and you will have no silencing at all. Yes, it will be loud. Very loud.

    Loud enough to make your ears bleed a little.

    Taking one of the silencers out would be a better option IMHO

    No  technical knowledge on my part, remove centre silencer, exhaust gasses have longer to travel before hitting a restriction and possibly moves center of gravity back a little bit.

    This could be a load of bo**ocks.

    I would agree - middle one makes more sense than the rear. Turbos live on having as low a pressure across the exhaust turbine as possible to aid spool up. Although there is still a couple of restrictions (cats and rear silencer) overall back pressure of the exhaust will be reduced.

    Only problem you face is that it will of course affect your Warranty.

    Weight wise - technically yes, but not a huge amount! ;)

    Why would that be?

    When I had my Ragazzon cat-back system fitted by my dealer they said that the warranty wouldn't be affected. Removing the cat, however, MIGHT affect the warranty, they weren't sure about that at the time.

    And what is likely to go wrong (warranty wise) by removing centre silencer????

    That would be a judgement call on the tester, i.e. if they thought it was too loud then they could flag it - but would need to be pretty excessive.

    Why would that be?

    When I had my Ragazzon cat-back system fitted by my dealer they said that the warranty wouldn't be affected. Removing the cat, however, MIGHT affect the warranty, they weren't sure about that at the time.
    The way I would see it in your warranty is that if by removing it, there was a knock on effect (excess wear on the turbo etc) then a dealer may just draw the line at the modified exhaust and say "There's your problem".

    Final Edit: Removed some opinion from this. Service book outlines what can and can't be done to the car for your warranty to be maintained. I won't be commenting on issues like this again as it will just end up opening a can of worms.
