Not sure on the price of the blitz (around £3500-£400??)as i havent bought one but im sure they are more exspensive than the ninja and vortex which are around £225 and £270, although scoobyworld have a deal on the vortex at the mo and its only £249! which is a good price, this will definatly bring out the burble you want and sound great. The blitz is a lush exhaust but whey too loud on full sing for me and the cabin drone will ruin my kids hearing for life,lol. Piss my neighbours off and probably me too after a week! The other two bring out the burble spot on as the blitz, for less annoyance on motorway driving.
