I am thinking of taking a crack at porting these. Does anyone have their stock ones that would fit my 2007 F150 5.4?

Also, has anyone ever done this before? Seen any gains?

Thanks,
Greg

 

I haven't heard about porting the stockers but I have a pair I pulled off my 05 5.4 a few months ago, have less than 25K on em sitting in the garage, no leaks or issues while they were on. If ya want em make an offer...

 

think he means intake manifold not exhaust...

 

no, I meant the exhaust. Just trying to figure out a price. I see them listed new for $90 and used from $30. Shipping is going to kill me. Also checking around the local junk yards to see what I can do. I don't want to invest a lot, maybe I don't gain anything, not sure. I got the high flow cats installed, it sounds a lot better, a little louder and deeper.

 

Shoot me what you think is a fair price, I have no idea. My zipcode is 65202.

 

they weigh about 10-15 pounds each, this is a guesstimate as no scales are in the house , usps shows about 14-15 bucks or so shipping it out and delivered in two days from zip code 27703, only if I did their online calculator right. You may want to check to be sure, but since you are from my home state, I will give em to ya for the cost of postage...

 

I wouldn't waste the time and effort to port stock manifolds. The gains would be less than shorty headers, and they wouldn't look as good.

 

porting the manifold would be a waste, same as shorties are.. even long tubes are questionable...

 

I know it may be a waste, but I don't just want opinions, I want data. If he gives them to me then I will do a before and after run with only changing out the manifolds. I need to keep my hands busy and not real hot on the idea of spending $1500 on long tube headers and high flow cats. Plus, I like trying things that I have never done before. Don't know much about porting so time to learn.

 

Send me your paypal address to mrpositraction@gmail.com. If it is less than $20 shipping, I will throw a little extra in for your time.

 

o.k., I can ship em out probably Monday, as I am heading out to the beach for a wedding today and not coming back until Sunday, I will pm ya once i get back..

 

No problem, I will be traveling all next week and won't be around to check email, forums, or send you money, so we can wait until the 2nd week of August.
