Anyone running FI Resonated test pipes and an axleback?
 

Anyone on here runnning Fast Intentions Resonated Test Pipes with an axle back? Does it sound raspy? I am impatient and don't feel like waiting until I get my catback, I feel like throwing the FI RTP on now, but I am afraid it will rasp and sound terrible. And knowing the labor I don't think I would take them off if they do sound bad. I currently have a Topspeed axleback

Little raspy, lots of drone. I have Beluga resonated test pipes and FI steel with 18" resonators. I will be adding more resonators or switching to a new cat-back. The rasp makes it a tiny bit dirtier than just the axle back.
