Great note, kind of a happy medium for volume
Live in Southern Oregon so shipping took a while but that was expected. Got the car up on floor jacks and it was easy to remove the exhaust with the exception of the bolt above the mufflers. Not much room to work. When I went to swap the rubber isolators off the factory mufflers onto the American Thunders, I noticed the front hanger bracket welded to the muffler was facing the opposite direction compared to the factory muffler. I took it to a shop thinking they were going to have to cut it off and fabricate a new hanger and weld it on facing the right direction. Turns out I was wrong, it managed to work anyway. I wish the instructions or website would have addressed that. The shop got them installed and welded to the pipes in about an hour for $100.00 I honestly have no idea how anybody can get this done in their garage on jacks in an hour or less, I'm not buying it unless they aren't factoring in the time it takes to remove the stock exhaust. The AT's sound great, loud enough for me (46 years old) but I wouldn't have minded them being a touch louder. I do really like the deeper throatier exhaust note. With the windows down they sound awesome (louder and great note). With them rolled up, they're a little louder than stock but not by much. When down shifting and slowing down with the engine's compression, they occasionally have a flat sound to them - kind of hard to describe but it sounds wrong. I've only got about 30 miles on them so I'm assuming based on other reviews, that flat sound will go away after i get some more miles on them. Based on other reviewers complaints of the paint flaking off, I painted mine with a heat resistant paint. I went with aluminum colored paint but I wish I'd painted them black. You can see the bottom of the back side of mufflers from behind the car and the black would have hid the crummy welds a little better. The bad welds really do stick out with the silver paint. I like the looks of the tips with the rolled edges and the 4 inch diameter looks great. After I bought these axle backs, I listened to the cat back AT's on the website and they were probably more what I was looking for in terms of the sound. A little more aggressive sounding but still livable for everyday driving.
