 Subject: 4.7 torque mods only
IP: Logged
Message:
My 2001 has pretty good ummph. i only have the HO cams and k&n drop in installed. Im installing a fastman 68mm TB also. When do i draw the line for intake mods before i start to open the exhaust as well? Keeping in mind i want best possible trq first.

You already should have put on a good 2.5" cat-back. I put on a Dynomax Ultraflo S/S system and the butt-dyno says it gave me an all around improvement. Plus, I got a slight mileage increase to boot.
I'm not endorsing this exhaust but, I am endorsing an after market performance exhaust if you want more power and torque. You just have to be sensible, no 3" true duals, etc.

I was told by several 4.7 owners that the 4.7 has really good stock exhaust manifolds and that it does not justify the cost to spend 400-600 on headers for the 4.7....any thoughts or dynos?
How about a 3" single exhaust. I heard single is better for torque vs duals

Don't know what gears you have, but switching to 4.10's will give you more torque (at the wheels).
I've also heard that headers are not much help on the 4.7.

Headers give you about 12 rwhp.

Shorty headers might give you 5-10 crank HP at the most. What you need are some true long tube headers, and a good merged collector. Other than that, you're wasting your time IMHO...

Nope, and I just can't seem to get everything I need to fall together. I might sell the damn design to someone who's already set up to build this type of stuff...but then I can't guarantee price. Either way, it's not looking good.
