My 106 gti used to pop the odd flame on overrun, standard with a de-cat pugsport system. Hardly noticable though, but you could hear the bang that came with it!!
Maybe TheJesus's ITB ph1 172 flames slightly as that pops like a b**ch, or at least used to according to his YouTube video!
Dont know what differnt system you got to mine but ive had the full milltek with a de-cat an centre box by-pass pipe an the usual IK from viper an mine pops an bangs every so often, more so when its cold. No flames though but hate to see what its going to be like on a re-map an manifolds done.182's dont tend to pop and bang tat much on any system i have heard is there any reason for this
My 182 Pops Plenty when Cold, I'm Running K+N, Decat and Cat-back system, I love it!!
Just buy a Twin Flamer Kit with the Spark plug if ur really that keen on Flames, Not my thing really but if u really wanna b spitting flames then thats 1 way of getting them!!!
