I got the muffler and installed it this past weekend. I'm very happy with it so far and I think it's exactly what I was looking for. Its got a slight bark on start-up, but then it's relatively tame at idle. It's also pretty quiet when cruising, but you definitely know it's not stock. Under full acceleration it sounds awesome, but not obnoxious. I'm detecting very little drone on the highway and that's with MDS on. I haven't messed with turning it off yet. I'll be a towing a boat in the spring, so I'll check back at that time to report on any issue with drone while towing. As others have stated, the quality is top notch. For those looking for a muffler that's not obnoxious, but still sounds good with minimal drone, the K&N might be the ticket for you. Also, to top it off, I scored it on Ebay for $175! Even at the regular price, it's the same cost as the Magnaflow, but with 304 instead 409 stainless steel.
