well just about any garage with a ramp could fit them....even Kwik fit if you trust them and can watch

not sure about the "guaranteed no MIL" though ....what they mean is if your MIL comes on, they will claim its not the fault of their CATs, its something else ...like the O2 sensor

Makes you wonder why BR go to to so much trouble developing their manifolds to work in conjunction with 200 cell cats retain the standard silencer and still gain a dyno proven 38BHP. Purdey never once threw up a fault light plus she lost 18KGMS of weight.

cats + manifolds from BR give those gains...not just the cats

Steve, may I suggest taking your 200 cell cats to BR and getting the job done properly . I honestly cannot believe bolting on yours will make any difference to how your car performs. Don't forget your car also has pre-cats are those to come off as well? If they do you are going to need some exhaust pipe, or are they staying? My performance gain on Purdey was as a result of fitting BR's sexy manifolds removing all the cat grub bins then installing race cats but still retaining the standard silencer with its valves. BR then set the valves in the silencer to open at 5500 rpm whereupon she had a straight through exhaust! Sounded like thunder! The advantage being that I retained a stealth mode upto approx 100 mph. If I pushed the sport button the valves opened immediately.

I do not wish to pour water on enthusiasm but firmly believe the job needs doing properly.

As AMpilote will say, the update to 200 cell cats alone will return performance increase in the order of 10/15BHP. Anybody can bolt these on, but the key to fault free operation is who did the integration behind the scenes. As JaguarJamie will state also, his 200 cell cats created an error code on his dash which he found a tricky problem to resolve

Bogie is right too in that the supplier might say the error lights are something other than the cats. The advice here is go to halfords and buy a 20quid fault code reader, if the codes are P0420 and. P0430 the problem is catalyst efficiency - probably takes 5 or so journeys across 300 miles to trigger this code.

However here, the OP seems quite sure (100% even) that this won't happen in the case of the parts he shows - happy days. But I would only make that statement to inform others after, say, 10k miles of first hand experience. And with the greatest respect to the OP, lately he seems to be making a number of statements with the intention to inform others without thinking if his statements are totally robust - but that's what peer review is there for I guess.

I know that I go on a bit about Bamford Rose. Taking my beloved V8S to them for some serious enhancing was one of my best moves ever! I cannot recommend the company highly enough!

Hi

Am I missing something here or are the cats on a vantage different to that of a DBS?

The 200 cell cats on a DBS don't have any sensors and as such I always thought it would be safe to change them error code free. Is this correct Bamford Mike?

I can see why vantage would throw them up as there appears to be sensor provision there.

Thx Tony

Unfortanatly JaguarJamie is dead (banned) so long live the captainjamie!

I have to be very selective on what I say in reference to my terrible experience with a certain company that sells cats for the vantage. The company whos name is very similar to 'rapidcopper' or 'fastgold' were quite unhelpful to say the very least.................... Blah, blah......

Isn't this the point of forums? To learn from others experience, both good and bad?
Cracking bit of info. I didn't buy an Aston to be treated with less dignity.
