Got it done on Monday and have been driving around with it since. We actually just kept it as a 3" until we hit tips, in an attempt to bring down any drone. Sounds beautiful and I'll post some videos of a cold/warm when I get home. Not too loud when driving in general, with the exception of the cold start which can be pretty loud. I only get a slight drone on the highway when I let off the gas or accelerate; keeping a constant speed is nice and quiet. The deceleration pops are great as well. Thanks for the original thread, as it really helped me out. I'll tack the videos on this post later.
