Can those numbers be achieved? Yes...possibly. I would simply caution people getting all hyped that this might not always be the case...remember those 'Tornado' things and their promises? Does anyone actually know someone who got what they promised with that thing? A friend and I, a few years back, tried one for kicks on a '97 Ram with NO results, power wise or mileage wise.
More power to those who plan on the purchase, just pointing out these may be lofty aspirations.

The dyno sheet was based on three runs. I'm on my third Corsa exhaust and they're a reputable company. Corsa is not selling $2.00 Tornado things on tv at 3am. You're going to pay big $$ for an exhaust from them.
I have one on my 2005 C6 Corvette. Notice that they don't make any hp claims for a 400 hp engine. I would think that they could exgaggerate
some hp/tq claim for a $45-75k sports car. In fact, they dont have any dyno sheets for the C6 since they only claim increased flow, no gains. On the corvetteforum.com it is well known that the Corsa set-up only provides gains when the front end is opened up, and then you're only looking at a few horses and quite a few bucks. I purchased mine for the more aggressive sound. I don't brag about a single horse or SOP claim from it.
It simply looks like Toyota left some scraps on the table. There are gains to be brought from this set-up or Corsa would not make the claim.
