Im trying to get the car quieter. I have a stock Integra muffler that im going to fab up to work, but that wont be for another few weeks.

I found insert cones that supposedly quiet things down, but am having no luck finding one in 2.5". Also traditional slip in silencers wont work because my exhaust has a turn down.

If anyone has any reccomendations to kill the noise, please let me know.
