Not yet. I'm considering having a play with the breathing on the car, though... the sports pipes just aren't quite "enough" for me. I think the cats are about to inexplicably pack in.

You will have problem come MOT time if you do that, better find some racing cats to reduce back pressure, providing you can get them for Astons!

Depends who does the MOT. I'd keep the original cats in a box (or should that be "basket" ) should the worst happen, anyway...

is it a 6 cyl DB7? i reccomend modifying the silencers on it. my uncle has got the square boxes on his '97 3.2 and they sound fantastic! very gurgly and very loud! i'm not sure if they are an add on or if they came with the works kit, but i'll try and find out some more about them.

I've read that you can cut the front two boxes off, weld the pipes together and have a throaty sound in return. Haven't heard of anyone actually doing it, but the suggestion has been put forward.

This has been done and witnessed by my indy while working at HWM. Apparently it sounds very nice indeed! I'm currently looking into options here, since Aston want the thick-end of £1500 for their sports exhaust, whereas dropping out two of the four silencers sounds like a much cheaper option.

Any other options gratefully received.

i took off the 2 rear silencers and put 2 straight pipes on and also used the original tail pipes,so it sounds a bit louder now

[goodlife]

Tony - who did you get to do this for you, and how much was it? Bit cheeky, bit can you record the sound and put the sound file on here so we can hear it? Thanks

[tony m]

GOODLIFE,i got it done at mr tyre,they are a national company,it cost me 60.oo

I have developed a proper multi branch manifold for the 6 cylinder 3.2L cars, this and work on the head gives a very hefty boost to the engine power,- something of the order of 50+ bhp.

Bearing in mind that cars with compressors desperately need extra flow on the exhaust side (as the inlet charge is compressed), this and the extra head work removes the rather lack lustre low speed performance and the mid range flats the engine is known for, without even having to change much else.

Though you might like to know there IS 1 decent AJ6 engine tuner out there and the results are really spectacular.

On blueprinted atmo engines I get a whopping 70bhp power jump, making the V12 cars look rather silly, thirsty and slow.

Don't knock it 'til you tried it
