I have loved this RPI axleback exhaust but am moving and selling the car this year so my RPI axleback exhaust is for sale. I don't have pictures yet as I am taking it off this weekend. But let me know if you are interested and I can send pictures.
It lists for $889 on RPIs site...
I'm considering getting the RPI Exhaust for my E60 550i. I have a couple of questions for you guys that may have already gone through this.
1) Is this the best brand you recommend or are there other good options?
2) Are there any performance improvements from your personal experience?
