I have a 2013 spark. 1.2, I have a cold air intake and a full catback strait pipe done in the same size as stock. It definitely gives off ricer vibes but when shifting at 5-6500 rpms it pops very loud. It also crackles and burbles at all rpm. I like this sound. But I'll be taking it to zzp this year to see if they can do a custom turbo kit for me. This forum is long dead but I'm hoping to find someone like me who loves their spark.
