I guess what I want is to 'free up' the engine so it spools quicker and generally doesn't feel as strangled.

Rob's quite happy with his 2.5" decat (3" Downpipe narrowing to the stock 2.5" where it joins the system) and the spool comparison between his and mine that I have logged and plotted is nigh identicle. The 3" comes more into it's own at higher rpm and power. This will allow the OE centre cat to be re-fitted.
