Well, since you asked,
They got bought out by TransAmerican.
My exhaust eventually melted the rear bushing, so I ordered a replacement set. Bushings that arrived were substandard. The old bushings were 1/8 wall for the inner and outer sleeve, both were seamless tubing.
For the rear bushing, the inner sleeve was 3/32" and rolled with an unwelded seam, the outer sleeve was 1/16" at least it was seamless.
Called RE today. Theytried to tell me these are the same, doesn't matter how they look, they are made in USA, etc.. when I ask the Rep. Why mine clearly say made in mexico? Ohh, North America same thing.
They are simultaneously already working on getting replacement bushings directly from the spring manufacturer instead of a third party, and claim to have never heard of one failing at the same time.
I wouldn't trip over myself to spend any cash with them again.
