Whats up guys first post here. I am new to the diesel world and I am becoming addicted quick.

I have a 97 long bed f250 auto (wish it was a 5 speed) 160,000 miles got her for a 2800 bucks

anyways I want to do the exhaust to make it breath better lower egt etc etc, right now I have no kitty or muffler just straight factory pipe my question is:

should I just replace the downpipe with a nice 3 inch down pipe for 80ish dollars

go with a 3 inch down pipe and four inch exhaust 400ish

or four inch dp and four inch exhaust 500+

the truck also has an afe stage 3 intake and edge programer

no body?

 

I think it's worth it, after i got my 4 inch turbo back Silverline system i spooled up alot faster and i got more boost.. it cost me like $300.00
IDK much about Ford but i say go for it, get a turbo back system u will love it!!!

 

Thanks for the input. I will check out siverline

 

u bet no prob man

 

come one guys only one person has any input?!?!

 

If i remember right but i could be wrong its a pita to get a 4 inch down pipe installed on that year of truck. I think you have to bend the firewall or so ive heard. I would go with the aftermarket 3 inch down pipe which would be more free flowing than factory. Then go to a 4 inch exhaust the rest of the way

 

Look up Tymar Performance and give Dale a call. Really friendly guy and knows alot about our year powerstrokes. I bought my exhaust from him not sure on the price but is wasn't breaking the bank. What I got was a stepped downpipe the goes 3in to 3.5in to 4in and then a 4in exhaust that dumps in front of the passenger side tire. Pretty simple install and sounds great. I was pulling the boat out of the water a couple weeks ago and actually had a dogde guy come over and compliment the exhaust.

 

Thanks guys, and yeah a four inch DP is a pain but I think it would be better going into the situation knowing that. I've also found some tricks that people have done to make it as easy as possible.

 

yeah go with at least a 3" downpipe, you stock turbo isn't the greatest, at 25psi of boost there is approximately 35psi of backpressure regardless of the size of exhaust, look into a different exhaust wheel for the turbo if you can afford it

 

What exhaust wheel would u recommend? And maybe a place to check then out.

And what would that do performance wise?


Thanks
