Was researching exhaust and saw one from a company I visited for a while. I knew of Thermal R&D when I use to have my first car (dodge neon, 10 years ago). It's all mandrel bent, stainless steel with band clamps. It's also a 3" system. Looks like a well put together exhaust. Sounds decent also.

As far as I can tell is that it's in the 600-700$ but can't tell for sure. No concrete pricing. Just to throw another exhaust into the mix.
