The performance exhaust you just installed is louder than you expected. It drones at certain speeds, and it's starting to get on your nerves (or the nerves of your passengers). Your solutions now are to either sell it and put the stock exhaust back on or live with it. Or, you can make it quieter. If you like that loud sound or you don't mind not being able to hear your passenger unless they scream, you don't need to read on.
There are a couple of inexpensive solutions. The first one is a silencer. You can buy these off of Amazon for pretty cheap and they are easy to install. Usually you just need to drill a hole in the tailpipe to hold it in place. I honestly don't know how well these work, many people have reported success with these. The second one is the solution I performed, which is to add a baffled Glasspack between the Cat and Muffler (that is if you still have a CAT).
Before you can proceed, you need the following:
A good muffler guy or shop (If you have a welder and a pipe cutter, know what you are doing you could do it yourself)
A quality Baffled Glasspack
Please be aware of the following Caveat: a section of pipe will need to be cut to fit the glasspack. This will void your exhaust warranty with the manufacturer, and secondly you will probably not be able to sell it later unless the person does not mind buying it with the glasspack. If you are OK with that, than no problem here. Also some Glasspacks wear out in a year, so you want to buy a good quality one.
I currently have an aFe Takeda Stainless Steel 3" Cat-back performance exhaust, and although it is not super loud, I really wanted to quiet it down a bit. The worst part was some droning I get when I am at high rpm and take my foot off the gas, which I find annoying. After installing the baffled Glasspack, there was about a 20 percent noise reduction and almost 70 percent elimination of the droning sound, of course this is just a rough estimate. The cost was $30 for the Glasspack and $90 labor and took roughly 45 minutes. The guy I used was super cool, I could have negotiated him down but this is what he does for a living, and he did a great job. He has been doing mufflers for years and told me that this was the best way to reduce noise from the exhaust without spending a lot of money and most importantly, affecting performance.
So if you like me like a quieter ride, this is the way to go
