not really i can see the the reflection of the flames under the spoiler, theres too much road noise etc. at lower speeds i get the pops etc but these must be further up the exhaust and i dont get flames on these as far as i know.
this was also a unique night to have had someone behind me to film it. i had done some previous flames but had not noticed them as they must have been smaller, so who knows how often i get them or if the conicide with any if the pops
i wouldnt know about the blue ones. i have wrapped my exhaust from the turbo to the decat and blipping the throttle helps produce little pops on the over run. this was the first time i had ever seen them it was quite a shock!
i had only recently put the car together..boost mods etc and i hadnt really got the car hot
