So I'm making a custom tray for my f6 tornado sort of as a little welding project to break up all the boring welding jobs I habve been doing throughout my apprenticeship and to just try something new since I'm yet to see a tray on a new style ford ute that suits and looks good.

My main problem is the exhaust system. It's all stock at the moment and obviously I'm going to modify it so it doesn't hang down but is there an issue with dumping the exhaust before the diff. I know it's no v8 and pretty much the only reason for this is so that it makes less work and saves money. I'm not sure though???? Any thoughts and ideas would be greatly welcomed

I wouldn't recommend it. Back when my ute was standard I removed the rear section of the exhaust (from the diff back) for a few days to do a rear muffler delete. The car was noticeably less responsive with the rear section removed. And the sound was loud/drowny and not very clean....The standard tune is designed to work with the full length exhaust. I would be modifying your standard rear section after you finish the tray. You will be able to get it sitting nice and neat up under tray. Do a muffler delete if you're after more sound but keep the pipes full length. ?

Cheers for the reply I JET. What about continuing a 3" exhaust straight after the cat and running one muffler and the y piecing it off with two hotdogs then run it up under the tray. Will this need a retune. Not really after power but a nicer note would be lovely. And needs to look real clean obviously

Staino is that you?

I have a tray back, and out of the cat 4" pipe runs into a muffler then exits just past and over the diff.

The 4" system I have is not as noisy as the 3" counterpart it replaced.

Power wise none has been lost.
