Exhaust HELP ZF-NP205 HOW???

[Slick67]

Soooo, passenger side

Driver’s side?!?! WTH

ONLY way to cope was to bend the pipe over / below the case?!?!?


FYI- it’s a 2” body lift, 351, zf5, np205… with an aux fuel tank. ***switching TO duff's shorty headers.

You are all hunky dory on the passenger side. But the output yoke on the driver side is exactly where the pipe needs to go
I am at a loss.

How have you all seen it done?

HELP!

I have not done the exhaust yet, but I plan to not have the aux fuel tank and then have the “y” pipe crossover right under the tail housing of the trans between the t case.

351W, 1 inch BL 2.5 SL, M5ODR2 and D20.......Yeah exhaust is a pain. I ran mine under the Tcase (no skid plate) as a temp solution and now 2 years later it's still ran that way. Plan was to cross to P side then once clear of everything cross back over to D side, Just haven't gotten around to it. Too many other Toys and projects.

Here's a thread with the exhaust routing I did for my ZF/205 combo. Shorty headers are a must and then ran the exhaust down the passenger side

LoL if I knew how to post a pic, I’d show you how it is now…

Passenger side- driver’s goes over the T case and hangs down like 4” under the lowest part of the frame….

How did you join them?
Like before the firewall? Or just under the bell?

Oh
Are any specific shorty headers preferred? Or will pretty much any work with this set-up?

BTW, THANK YOU!

Bronco hut used to sell them but "they gone" so you have to get them from Sanderson now. BTW the link is to GT40P headers......so make sure you get the ones that fit your heads and transmission.

I run the ones linked above....My W has P heads....

Previously I kept them as true duals all the way out the back, dumping on the ground just after the rear axle.... don't do that lol. It stained the driveway and blew dust everywhere. Now I have both merging into a 2 into 1 muffler just behind the passenger seat.

I have Sanderson shorties, they work well but I think most shorty headers would work for what you're doing. I had long tubes before, but with where the transfer case output is for the front axle you cant run long tubes https://sandersonheaders.com/product/ff7-small-block-ford-bronco-header-set/

I can take some pictures tonight if you need them

so the Duff’s shorty headers aren’t short nuff?

 

[Timmy390]

That I can't answer. I know the Sanderson's work with 351W, 1 inch BL 2.5 SL, M5ODR2 and D20

I'd call duff and see what they've got to say

Ha!

They were not sure! The zf5 AND the np205 threw ‘em a lil curve. Your link was more help.

Sounds like maybe the o2 sensor port is supposed to be facing down, was their only feedback.

But I’m buying their whole stainless kit with the ceramic shorties… knock on wood, it SOUNDS like it should fit with minimal mods.

I ran mine around the 205 and under the frame. Made a brace for each side out of some 3" angle iron and then built a custom skid plate to protect the exhaust pipe and my on board air tank. ( where aux gas tank goes) It ain't pretty, but I do wheel my Bronco and haven't had any issues yet. I now have EFI with an intank pump, so the Carter fuel pump is no longer on the pass side. Good luck with your new stuff coming in!
