Are you referring to RSM Racing in Canada? If so, no I have not heard of anyone buying or installing one of their systems. I mentioned the Corsa because it seems, after lengthy debate in the now-closed GM Forums site, it gave the best horsepower and quality return for the dollar. It's actually the Caddy STS system, with the s-bend section before the muffs re-bent to a steeper angle. You would need to find a shop to have this done(mandrel bending) during installation for proper fit and to center the tips in the rear bumper cover cut-outs. Corsa is aware of the desire for an Aurora specific system, and were on the verge of producing them if they collected enough requests. Caddyinfo.com has all the dyno results posted using the Corsa. Also, to hear it on an STS, go to corsaperf.com. Someone did make a comment about the RSM system being an overpriced, pieced together set that any performance muff shop could do cheaper. I can't verify any of that. I still have a stock exhaust, but want to add 2.5" pipes at the Y, with Magnaflow polished muffs and their 35175 tips that resemble the factory ones.
