headers,...and other performance mods??

[snafu4u2s]

i need some help! would like to know what you guys would recommend to do next with performance mods. i already have the flowmast 50 series SUV dual exhaust setup, and a jet performance chip. What should i do next ...headers,intake,MAF,TB etc. i have roughly 1000.00 to spend. oh by the way its a 99 sport with the 4.0 SOCH. and if i do install headers, will i loose any back pressure and will it change the way my exhaust sounds any.

people will see your threads and they will get answred just be patient.

i would get a k&n or mac intake. then i would do a tune upthere is no throttle body and for the maf you will have to custom wire up the iat sensor. i would rethink the jet chip and maby go with an apten it can be customized to whatever you want. or of you want to go big there is a supercharger that adds lots of power

If I were you I would go with the intake kit. It works well with the performance exhaust. Then get a BBK throttle body or chip. Both of those mods work good too.

so no one recommened headers?? i was already planning on getting the K&N intake along with the BBK throttle body. i was just thinking that the headers would make my 4.0 sound better along with added performance.

it would help some, but minimal at best.... also why jet? from all i have heard about jet, they arent that good

I also recommend the Mac Intake $149.95 for your next upgrade. It will make a noticable difference on your V6 SOHC. The next step would be the Pro-M 75mm Mass Air Sensor $224.95.

There is no throttle body upgrade available at this time. The BBK is strictly for the V6 OHV.

The JET chip is actualy quit effective. We have had success with the JET. The chip will perform even better with the other upgrades.

There are no headers available for the 99 V6 SOHC per say. We do have JBA Headers that will bolt up to your engine, but the head pipes won't connect. You would have to have the head pipes fabricated. I have not heard of anyone trying this yet. But I am sure somebody will try it soon enough. The gains from headers is not huge, but noticable. The gains slow down after you do the intake. The headers & the Pro-M still offers a net gain in horsepower and that is what we are looking for.

The Mac Intake is one of the best power upgrades available.
The picture shows the Mac Intake with the Pro-M 75mm Mass Air Sensor.

will the maf fit the 99's with the intagrated iat. or do ihave to splice one in
