Sound Clip of 2"ARH and B&B Fusion Exhaust
I recently had 2" ARH headers installed with green cats and a B&B Fusion exhaust. My supercharger pulley was also changed to maintain 8psi. ARH custom made this set in six days!? as it has the green "GESI" cats. On the street it sounds more european at normal driving speeds.
Update: Fitment was perfect and no leaks. Did not have to modify the tunnel plate. Also, I can see why there are discussions around 1 7/8" vs. 2" headers. I asked for 1 7/8" headers. My tuner convinced me 2" is best. If there is an issue, it is below 3000 rpm. After 3000 rpm, there is no debate, at my horsepower level. My tuner focused on torque below 3000 rpm during the tuning process.
Hopefully the video/sound clip works...
