I've been deciding on an axleback set-up for sometime, and I think I've narrowed it down to these two. I'm aware that they are both known to drone, but can anyone with experience tell me if its manageable for a daily driver? My set-up would be stock other than the axlebacks and a CAI/ Tune. Any suggestions on which way to go?

 

I have read that both of these sound nearly identical. If they do indeed sound a identical, I would go with MACs as they are a little cheaper. I have MACs on my car car but I have a catted X and resonators which help reduce the drone. Not sure if it's the x pipe, resonators or both. It does drone under hvy load but I almost have to force it to drone. I had magnapacks with a prochamber and hi-flows and that set-up droned alot more.

 

Thanks...I am leaning toward the MACs right now for the $50 or so savings over the Flowmasters. Anyone else?

 

I have the aggressive MAC's with no cats and they are louder than my Flows I had on before.
