O YES WE (THEY) CAN !
if flames are coming out of the pipe, then you commit the offence of Dangerous Driving
(full wording is "knowingly driving a motor vehicle on a road in such a condition that it MAY cause danger to other road users or pedestrians")
Of course, if it's never happened before then it cant be done "knowingly"
It carries a choice of penalties from a warning, through an endorsable fixed penalty (£60 and 3 points), to a court appearance with a fine up to £5k, 6 months in jail, 10 penalty points and a discretionary 12 month ban.
That said, i can't believe that many coppers would be too bothered by it - after all, it's not like its a Corsa 1.2 or Saxo with a 4" exhaust can and a million watt stereo.
Be aware that the VOSA also do roadside checks on emmisiions, and they have the power to put your car off the road (immediate or delayed prohibition) - as have some of the Old Bill (but i won't give you a ticket

)
