Stealth Mods
Do the exhaust manifolds from the LS7 Z06 fit an LS2? I'm not expecting the same gains as LT headers would provide, but will this provide any benefit? Any idea what they might cost?

i would suspect you would get better gains with a cam or rockers. esp. since you can't tell simply by looking. a.k.a. stealth.

They fit. I've done it, and a few others on the forum have as well I believe. Need the full system to include cats and center section. I just hooked that up to stock mufflers with 3" pipe.
Picked up about 10 HP across the board on HC motor.

Gears are as stealth as it gets and have the best performance increase. Next mod should be to port the existing intake manifold. 3rd would be a small cam increase. 1.85 rockers with comp 918 springs are 20hp and look stock except for the color of the springs.
The LS7 exhaust manifolds dont look stock.
Some dealers have a deal with mods that retain the full warranty of the car.

they will fit on thehead but u would need cats and center section as mentioned. lots of money to be stealth but they do not look like stock at all. they look like shorty headers as mentioned above

There are no clearance issues at all. The stock heads have round exhaust ports and the LS7 headers have "D" ports, so they don't quite match, but I have Lingenfelter Stage II LS6 heads and they have D port (just a little smaller) so it didn't matter to me. It will bolt to the stock heads as well and I don't think the shape will make a difference.
The only other thing you will need is O2 sensor extensions as the sensor bungs are in slightly different locations than stock. I paid $750 for the setup for mine from John Page's Z06 at 21st Century MC. Don't know if that's a good price or not, but should be more sets out there with as many headers going on these things.
