I am very pleased to announce that my car does officially, give good flame I met a visiting P.Heads mate at the motorway junction 5 mins from our house, turned into a lane, booted it a bit in second, reached the car in front, lifted off... and apparently the whole road lit up! Tony said that all four tail pipes, simultaneously and independently whacked out a 2 foot long blue flame (yes yes, childish I know, but ultimately very satisfying)
Al, what sports exhaust are you running. I have been behind several 355s at night fitted with the Tubi-decat setup.. I have also seen 'electric blue' flames emitted from the rear exhaust tips.. as you described they appear to flame out simultaneously from all four end tips.. it looks awesome, you should get someone to drive your car and follow it as this is something you HAVE to see! From what I have seen they appear to flame on every up-change with the aid of a 'blip' whilst changing up the gears. Very common on 348s and 355s with the cats removed and a rear sports silencer.

Wouldn't blipping the throttle on the UP change totally mis-match the revs to gear? I understand the principle of blipping to match the revs when changing down, but up? Mind you, if it gives me flames

I may be wrong but I believe if your car is showing "flame" there is something drastically wrong with the combustion and causes longterm irrepairable damage. It may look good but most racing teams try to mix the ingredients in the chamber for perfect combustion. Enzo use to have a 12 cyinder cigar lighter in his office, tuned to give the perfect flame for an Havana.
Its actually quite normal on de-catted / turbo cars with very little in the way of an exhaust, usually a high performance car will merley burble a bit on the over-run, with the unburnt fuel burning up long before it would hit the tail pipe, as Tubi'd / decatted cars have less to constrict the gas the unburnt fuel gets ignited by the first (and in this case) last hot metal baffle it hits, shortly followed by a nice stab of flame out the end. or at least thats how a Porsche tech once explained it to me (admitidley he did have to use a powerpoint presentation and finger pupets to get the point across!) on turbo cars the flame usualy comes out of the pipe the wastegate dumps into it may not be very fuel efficient but it sure scares the hell out of Corsa drivers in traffic!!!!
Surely it cannot be purely by changing down? but more simply by the act of lifting off the throttle suddenly, releasing the unburnt fuel. And I know in theory that flames could signify potential engine mis-running and possible damage, but this is not every time, only when really caning it and apparently (according to the guys on the Wolds run out a few weeks ago) is just little flashes now and then, not the impressive display I managed the other night
its not the actuall lifting off, more a change in the way the enigne is being stressed (from full power to no power) apparently nothing to worry about, if you want to stop it change back to the factory setup, the only difference is the small pops can't be seen (but they still happen) I may alos be wrong but when a car really does back fire doesnt the flame / soot come out of the intake, seem to remeber this happening when trying to get an old x1/9 running (quite funny watching somebody's overalls being set on fire whilst trying to set-up the carbs and timing!)
Tempted to buy said engine check these for flames guys http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=2983&item=5548558930&rd=1 Dale.
Sounds good to me lee,the rear seat's will have to go m8 and a rather large hole in the tail gate,mid mounted megane cs jet im sure the police will love it when you light it up at the trafic lights lee, Dale.
