Cherry bombs for the win! I even put them on my Gen 3 Hemi! I just like the way they sound. To be honest I do not think there is a lot of difference between them and the purple ones! I always went with the cherry bombs cause they throw in great go fast stickers in every box! And well cost of course. I don’t think you can go wrong with either of them. Purple/ cherry bombs. I mean seriously, as long as both will set off a streets worth of car alarms who cares right? Hah!
