Exhaust Upgrades for 5.4L V8

Has anybody experimented with or installed any type of exhaust/header modifications directed at increased performance of their Ford van with a 5.4L V8? Any installers on the West Coast. I've e-mailed several companies and no one seems to want to do so. Any other available aftermarket modifications that will increase torque/horsepower on these gasser engines?

Thanks,

Bill S.

Re: Exhaust Upgrades for 5.4L V8

On the 5.4L, your best bet is with a cat-back system. We did this on my brothers expedition, using a MagnaFlow setup. Nobody makes long-tube headers for the 5.4L, and shorty headers decrease low-end torque. The cat-back setup add some oomph all arounds. It was noisy at first but mellowed out after a few weeks.

I put a Flowmaster 40 with a 3" tailpipe on mine. All it does is make more noise. It has a great sound at idle.

5 Star Tuners advertises that they can make it feel as though 2 cylinders were added overnight.

O.K.,

Does anyone know where I can get a cat back system installed in SoCal?

Thanks

PM "LeadDoggy" on here. He's got a 5.4L and lives in Thousand Oaks or something like that.
