99'Z28

I have a 99'Z28 M6 and I not sure what mods to do next. I've had a 96' & 98' mustang GT and I knew what to do to them, but I'm not sure on the LS1. I have the whisper lid(is there one better than the other?), underdrive pulley, K&N filter and 3 1/2 cat back with flowmaster. I thought about a ram air(cold air) induction, programmer, gears, t-stat, maybe headers and a offroad y-pipe. Any help would be gladly welcomed.

Long Tube Headers, gears (4:10) and a proper DYNO tune, is what I would do next. That should get u between 50 and 60 rwhp (around there anyway).
When ur 10 bolt pukes then go for a 12Bolt Moser.
Might wanna get a good clutch also.

Thanks. How bad are the rear ends in the f-body?

I agree with Sharky. 1) LT Headers 2)Qtec Cutout 3)Tires 4)Gears 5)Tune
As far as rears go, on a scale of 1 - 10, I'd give them an 8, depends on how you drive. IMO.

Thanks for the info.

The rear ends are fine unless you regularly use sticky tires. Using slicks will quickly kill the 10 bolt rear. Also when you begin approaching 350-400 HP at the wheels it's time to spring for a 12 bolt.
