Very common with the SR. Some people love it. It doesn’t bother me much. With RB, it spits flame sometimes. THAT I like. ---

Backfires are sooo sick…mine does it when its running hot. I wish it just gargled away every time I down shifted. Flames are way cooler for sure. ---

my ka backfires LOL… running rich for sure. KAs are rich pigs. MAF possibly (i need to replace mine, i had a problem with i several weeks back… when i hit it, the problem goes away… go figure). If you get a chance, do clean your MAF. Did you get your car tuned? Mods/upped boost but no tune? If so probably a good idea to get it professionally dyno tuned. Backfiring on your own car is not cool in my opinion, it is only cool in videos. I rather use less fuel, grab less attention, and make more power haha. Btw, do you have a cat? ---

I loved the little farts she did and when she shot flames. If you’re wondering why its doing that now, its the timing shes running really rich. I had her richened out a little for better winter performance (colder air meant fuel burned more efficiently). Just throw 91 in her and shell run much better! ---
