Its an anti lag system that keeps the turbo spinning ........... but in the car you saw it may have been a leaking manifold......

More likely a flamer kit to make people think it's an anti lag system.

Or he has a very very wild camshaft (which being a chav...I'd very very very much doubt it).


Legally, don't know.. If it makes loads of noise then you have a case, or if the emissions are too high.

it was very irritating banging fire cracker noise no flames etc (btw i never knew flamer kits make noises)

That sounds like anti lag to me

Sounds more like a failing electronic ignition system to me.....

I reckon by law that exhausts have to be quieter than that.

I was at Scoobyclinic a few weeks back, and Adam & Pat were telling me of a "Pops & Bangs" map that they had done for a customer. The basics (which are a bit beyond me, so don't flame me if I get it too wrong) I was told are that the ECU is programmed to wildly adjust the ignition timing on over-run so the fuel doesn't get ignited in the cylinders, but rather gets pushed down the exhaust where it combusts due to the heat causing massive backfiring when used with a decat. Sounded ridiculous to me, and apparantly the guy who had it done was in a hurry to get it removed after a rather embarrassing scene on a US military base he was working on.

Boys and there toys, eh

Poor Guy

hehe. my 73 gt6 backfires and spits flames. im probly the only 18year old with a popping banging flaming exhaust which is all natural.
