I guess I'm hunting around on all the forums to pick up any info I can on better hp or mpg. I'm driving a nice 03 Expy 4.6, with TP 93 performance tune and an AF1 intake. I am considering the e-fan mod, but am wondering if re-doing the exhaust w/ the AF1 intake would help hp in the below WOT range of driving first. Not really interested in the sound. Mosstly just better performance.

Any thoughts? What is a good manufacturer/exhaust setup for the Ex?

Thanks for your input.

 

I'm a Flowmaster guy when it comes to exhaust I like the sound, gas mileage isn't my biggest concern, but a Flowmaster kit could get you maybe 1mpg more and idk about AEM intakes, i'm about K&N which will save gas
