Gents, I've tried searching and reading what I can. Is there anything to be gained by switching over to the R exhaust? I already have a tune and catless longtube cargraphic headers. I love that I am not much louder than stock now, so I don't want to go too loud with an aftermarket exhaust, but one of our local guys has a R exhaust I can have for a 200 dollars that was a take off.

Thanks!

The down pipes are a little larger by 5mm vs the S
So a small pick up from less back pressure and better flow

Personally, I don't think you will notice an improvement. You hace already removed the cats, which is the biggest thing for power. You may want to switch to a BMC air filter etc.

The Black Edition's in 2012 did this from the factory. I think that is where the extra 10 hp was supposed to come from. I don't think it will do much for you though.
