I got Custom Piping done 2 1/4" from the cat back in my GSR 92 Hatchie, i have a shitty ass muffler, i want my car really quiet and im wondering what universal muffler will keep this car quiet. because im getting to much complaints around my house that its "too loud".
you want a straight through design for flow reasons. They can get pretty loud. However, if you get one that is larger around and longer, it takes the sound down quite a bit. I just put on a muffler made by Vibrant. It's big, but it flows well and it's not too loud.
