Review: Looks great - Not too loud and would say it’s perfect for someone that wants the noise but has close neighbors they don’t want to wake up. Drone isn’t horrible either
Review: Just what I was looking for - The desertcart product information is a little bit lacking. This is what would commonly be referred to as an 18" muffler as it has an 18" long case. The case is an 18x5x8 oval. I had this muffler installed in place of stock on my GMC Yukon with 5.3L V8. I wanted something that would provide a nice, deep, healthy exhaust note that actually let me know there was a V8 lurking. However, I did not really want it to be loud as this is to be a family vehicle and we drive nearly 1,000 miles, each way, 2-3 times a year. I am happy to report that there is no mistaking the presence of a V8 but there is absolutely no drone whatsoever, the neighbors will never be bothered by it early in the morning or late at night, and even my wife didn't have anything against it after I had it installed before she even knew I had it. I might even consider recommending a 14" version if you don't mind a little more noise. Most pickups I hear with a modified exhaust (which is very common) are definitely louder than mine. Your call. UPDATE: September 2018. My review from above stands. If I was to do it again, I just might go with a slightly smaller and thus louder muffler. But without having tried, I can't say for sure. I still know there's a V8 in there when I hit the gas, but it's quite muffled. I suppose for a full size and slow SUV it's still the right call...however it this was for a pickup, not loud enough.
