Re: Exhaust System Upgrades (aftermarket)
Difilipo Headers.
Mate you made a great choice.
These are one of the best custom made set of pipes on the market.
You could have even bought it in kit form so you can custom weld the bends yourself.
I've seen these guys in operation on one of my favorite programs called GASOLENE (TVS thursday nights at 8pm, after 4WDTV) and they know their stuff.
So when are you going to see what it does down the quarter mile.

Re: Exhaust System Upgrades (aftermarket)
Di Filipo previously used a mild steel set-up/headers for the T30 xtrail, so it is nice to see the catch-up with the market and improve on their design.
I'd still be interested to see the proven gains of their systems as well as the cat. converter type they use, so we can make a comparison to other systems.
14KW gain as a result of a full exhaust system upgrade is less than expected, so maybe Darren needs to look at having one of the xtrails with the new system dynoed to get confirmed readings, as I believe the gains should be more than that.
Price-wise, the system is very attractive indeed.

Sorry, I should have added that the 14 pick up was with a header/cat only, not a full system, so the dyno before and after was only based on only the headers and cat added.
Well, the headers and high flow cat (what brand and specs?) form the bulk and main part of the exhaust system and the rest is pipes and resonators, so the gain provided is still low with those mods compared to an existing cat. back system that can provide 9KW gains by itself.
Do you or Di Filipo have the before and after dyno chart for us to look at?

just waiting for some Hiclones, looking to see if I can stuff 3 or 4 in there.
Hiclones are a total waste of money. Read details HERE and reviews of 10 xtrail owners who tested them as part of a group-buy we had years ago.

Sorry I can't provide much in the way of tech info, but at the end of the day I'm very happy with the product as well as how much I spent on it.
More info. would have been good to have for comparison purposes for other members and to provide an alternative to an existing system set-up.
You being comfortable with it is all it matters to you of course and what counts at the end.
