Looks and sound are great but the dude didnt bend the pipe over the lcas enough. When he put it back on the ground the pipe is resting on the lcas and makes an annoying knock at a stop. There is still some resonance at certain low rpms. May look into a j tube at some point but im disappointed that more time wasnt taken during measurement. Dude created days of irritation for me because i cant go back to get it fixed til tuesday when im off. Smh.
