Hi Paul A valid point, I am also entertaining removal of the primary cats on my DBS but not sure who would do the re-map here in Australia.

Hi Mike. I'm seriously considering the purchase of a >09 DB9, having watched many of your videos (as well as Steve's from aston1936) as part of my research. This primary decat sounds like smart futureproofing, as I would intend to hang on the car for a long time. The exhaust becoming actually a little less loud would be more of a pro than a con to me personally. My question is: I'm based in the Netherlands. Would a primary decat be possible on a parts exchange basis, where I'd send you my manifolds and I'd receive a pair of gutted ones? And could the appropriate remap be done remotely, i.e. via remote desktop or at a local tuner uploading your files or following your guidelines? Kind regards and thanks in advance for your advice. Frans

Hi Paul, I have a 2001 Db7 and recently put a lanarni center section on it. sounds great but was wondering how much horsepower increase I would get.

After watching your video today I removed my AM V8s secondary decat 😁

Very helpful vid! If you cut out the first cluster of cells on the oem 4.3L cats as you suggest, will you have to tune out a CEL? My initial thought would have been to cut out the cells after the second o2 sensor for similar gains and no CEL. Any thoughts?

[@karlstamper9243]

It’s to do with the 2nd sensor holding the gas pressure - I assume

Mike- regarding the Primary cats, what parts do you suggest removing for my 2003 DB7 V12 ? 3:53 3:54

Thanks Mike 👌, 💯

Hi, I’m planning on replacing the cats on my 4.3 by the decats offered on your site. Problem is I live in the Netherlands so won’t be able to come over to do the remap. Is there a possibility to do this in another way?

Am curious on health related draw backs on decreasing number/size of cats or completely removing
