The shell I bought for my k-swap use to be a turbo car, so it has a big 3" mandrel bent straight pipe and what I think is a magnaflow muffler. i got the motor in the car and running and it is LOUDDDDDDDDDDDDD as all hell. Trying to get some ideas to what a good performing yet still pretty quiet exhaust would be without spending a fortune. A hatch I had WAY back in the day had an apexi ws-2 on it, and it sounded good, and was nice and quiet. Was wondering if there was anything else.
