these videos are exactly the sound I'm looking for. Your car sounds awesome. Any chance on a windows up/windows down in car video?

Also, how'd you time the dual conversion? Drove the shop with the new bumper on with the right side cutout empty? Or did you have the shop fit everything?
Thanks I'll try to get that for you!!

The body shop put on my new bumper and diffuser, then chopped off the muffler, at about the rear axle, in order to fit the diffuser and everything.

We all thought it sounded pretty good with the muffler chopped off. So I drove to the exhaust shop that way (once the body work was all completed) and just kept the muffler delete, thinking I could add always add a muffler later on.

It droned really bad the first few days I had the conversion finished. But since then it has actually broken in nicely with minimal drone. I love it.
