the rest of the exhaust is all stock and in good working order.
volume is difficult to tell on a YouTube video. that's why I tried the before and after with the same camera in the same location.
I will say it wasn't the overall volume that drove me back to stock so quickly. it was the quality of the sound, particularly this low frequency drone when under light load. it is the type of sound that just cut right through my brain. instant headache, hence it had to go.
like I said before, this little exercise taught me a lot about what I like about this car. I thought I wanted this car to be sportier, but in the end I appreciate the GT qualities it has.
