Still has stock headers and exhaust.

Doesnt say if it was pump gas or race.

Imagine what a full exhaust would do to open that thing up!!

Yeah probably tune it for 750-760whp, thats almost 200 more whp than stock. It might be race gas or this car can make some huge gains over stock.

I would say 760rwhp w/ full exhaust would be a conservative estimate if it's making 740rwhp w/ stock manifolds and stock catback. I'm guessing it's on pump gas but who knows.

Yes but the corvette has a mild to wild exhaust switch. Which bascially opens the exhaust system up more. So idk how big the gains are from the wild setting with stock exhaust compared to aftermarket.

Never heard of a mild to wild switch, that like a cutout?

Since all the Zr1's, Z06's, and an option on regular C6's come with the butterfly valve exhaust, this "mild to wild" is just a setup that you can install where you can control that exhaust valve instead of the stock car opening it up only under hard throttle. Here it is in action. http://www.ls1.com/forums/showthread.php?t=118084

Yeah it has the power to pull mid 9s but that would require some chassis and suspension work to get it to hook better. I think they just wanted to show what it could do with power bolt ons and sticky tires.

With just bolt ons it traps as high as liter bikes and some Busas. Wow

Was there a price listed? I didn't see one

[Hi-Po]

Wow, holy shit, Jebus!

Did I miss anything? Thats just crazy.

So what's that worth in terms of hp? Like 5 or 10 maybe? I think you must have included the wrong link as that had nothing to do w/ the butterfly exhaust...lol

My bad, idk how that link got there ha. Just go to youtube and type in mild to wild and there are some decent videos of it working.

[Johns00Z28]

Cool thanks I'll check it out.

Well the stage 1 kit is just under 3k. So i would assume 5-8k for the stage 2.

[NYPD]

That is awesome! Would love to see it after some suspension mods.
