More power on my grown 352xl

I have done some research, and would like some feedback before I proceed.
To get more hp and torque the first place to start is air flow, both in and out.
I have looked at various kits and mods at the front end costing a few hundred.
It seems the easiest and cheapest way to start is to simply put a high flow muffler in to replace the original or to put in a straight pipe. Only a hundred or so.
Has anyone done this and what were your results?

I'm all stock on my mh. I would love to see some statistics on what you really get for changing out the muffler. I think if you change the air intake fileter to a onee that is more air you may get too much noise when you throttle up or down shift.

I think if you ar elooking for more hp and torque you may want to chip it.
Hopefully others will jump in.

You can look into performace chips. I believe that they'll offer some power improvement if you run 91 octane and run a tune that optimizes that. The people of Ford Truck Enthusiasts forum rave about 5 Star for the V10. I'd be leary of promises of higher power while delivering better mpg...more power always takes more fuel.

FWIW, high flow muffler or straight pipe will only make more noise IMHO. Increasing power is always about finding the limiter and improving it and I doubt that exhaust is the power limiter.

Performance in my motorhome is everything they said it would be............

Zero to sixty in 3 minutes!!!!!!!

On the other hand.......my motorcycles have done much better in the quarter mile..........but don't sleep nearly as many.

Mine has the "Full Banks Package", Intake, headers, mufflers, pipes, Trans-Command, and chip, and although I have a lot more pep than my last V-10, I don't even see 1/2 mpg more. Did I say a lot more pep?

I never even go 50 miles without one of my Jeeps in tow, so factor that in as well.

I changed out the air filter assembly. Replaced it with the Banks Cold Air Intake System. Basically it comes with a K&N Air Filter and it's hundred times easier to access the filter. It was a bit of a concession from CW because of some service installation issues. From a performance standpoint I have a better pedal response. As for better MPG- Nothing noticeable, but I do climb hills better than before I added it. I'm able to maintain speed on the climb without turning the high-screaming rpms to do so. As for the noise there's no difference I've noticed.
