I respectfully disagree. The engineering and development costs I estimate to rival what we put into our header, upwards of $100K. We spend the better parts of a few weeks going the 'throw a dart at the wall route' and it was fruitless. I think in total it was like 27 combinations of things we tried, plus a couple off-the-shelf products (Q300 & Cobb off the top of my head). In the end we went with a steel cat-back as it resolves 90% of cabin sound/drone when compared to stainless. It's cheap and starting to rust, but I can hear myself think and it had no problem making 597whp

That would put you in rotated kit category essentially. We've not gone in that direction, and having already spent development money on the kit we have, I don't see any benefit (from a performance standpoint), but more cost. Reverse rotation in that location would cause other conflicts as well with brake lines IIRC?
