I'm not familiar with that company, but if they claim that type of horsepower, make them provide you with the dyno test results!

In small print does it state "30 hp after professional dyno tune and these additional parts..."?

That's more of what full length tube headers might provide, but certainly not just a catback exhaust.

The CORSA catback claims are half of that and they'll provide test results.

Never trust HP/TQ claims unless they have before/after Dyno results for your exact vehicle. Even at that, you'll want to read the fine print to make sure the truck was stock. As for mileage claims, as we all know, there are plenty of factors that come in to play for that.

 

But they don't have a lot of info on their exhaust, no specs, no cut-outs, etc. Well, other than the crazy HP claims. Looks likes a typical stainless steel mufflers, baffled design (ie. not true free-flowing like Corsa/Magnaflow), etc. But I'd imagine it probably flows a bit better than stock. Flowmaster also uses baffles to create their unique sound.
