Description Extended Information
Looking for an exhaust for your Early Bronco? You've come to the right place. James Duff is the premier Bronco supplier with over 50 years of experience. We didn't take any shortcuts in bringing the best 2 into 1 system to the market. Works great with several different muffler choices to suit all types of powerplant combos. Learn more below.

Our very popular dual exhaust kit fits the bill for a great deal of Bronco owners, but a lot of owners with aftermarket transmissions and transfer cases have also been requesting a system that you can install in your driveway or at your home garage using simple hand tools with NO WELDING. Our new 2 into 1 kit does that!

  • Bolt-On Installation
  • Great Sound, from Mild to Wild
  • Fits 289, 302, 351w and 5.0
  • No Welding Needed
  • Works with shorty headers
  • Leave the guesswork behind

Head and merge pipes are 2.25" then mid-pipe and tailpipe are 2.5", exiting behind passenger side rear wheel at 90

It is designed to work with Drake and JBA 1966-77 Bronco shorty headers on a 289 / 302 / 5.0 If you are running a 351W, the headers won't fit without minor modifications, see below. If you have not already purchased headers, you can add them in Hi-Temp Black, Stainless or Ceramic coated and they can ride along in the same box to save on shipping. We also have a version for use with stock Bronco manifolds. See #3061

This kit is all bolt-on with a hardware kit and detailed instructions which include info on how to properly install the shorty headers we sell. No welding required. This exhaust comes with all the necessary hardware, clamps and hangers.

Muffler choices, quietest to loudest:

  • Stainless steel Magnaflow- Nice, resonant mellow deep sound
  • Flowmaster Delta 44- The Signature sound of the 40 series without the overpowering drone or in-cab resonating
  • Jones Full Boar- Deep more aggressive tone, comparable to a Flowmaster 40 series
  • Cherry Bomb Pro- Deepest most aggressive tone of the 4 choices
Works with:
- 289 / 302 / 5.0 / 351W
- 2" or more suspension lift (Min 2" lift required)
- 0-3" body lift
- Dana 20, Atlas, NP205
- C4, 3 Speed, NP435, AX15, NV3550 (Still testing C6, AOD, 4R70W, ZF 5-speed)


*Not tested on 1976-77 equipped with catalytic converters.

  • Shorty headers will make contact with inner passenger fender
  • Shorty header collector flange on some EB's will make contact with the frame and need to be clearanced. NOTE: If you are using aftermarket motor mounts that are taller, you will probably avoid this issue.
Disclaimer: this 2-1 exhaust system is designed to work with the stock transmission crossmember or the Advanced Adapters crossmember #3654.

This system with the shorty headers was a snap to put on, and boy howdy does it sounds good. Like unleashing screaming demons at push of the pedal!
Can’t be more happy.

Reviewer: Tyler Kleaver from Sault Ste Marie, MI United States  
I’ve never dealt with an exhaust before. With in 4 hours I had the system hung and in place ready to go. Everything fit as needed. I truly enjoy the sound from the cherry bomb.

5 of 5 Perfect sound ! September 4, 2019
Reviewer: Willi Hoffmann from ARTOIS, CA United States  
I replaced my whole exhaust system including the headers. I ordered the whole new system including shorty headers from Duff. My 71 Bronco has a 351w and 2 inch body lift. The exhaust system fits great. You have to take your time and line the parts up right - this is very important. The system has already threaded holes for 02 sensors !!! Perfect for my as I installed at the same time the Holley Sniper EFI system. The exhaust system gives you plent of space on the left frame rail for the fuel pump an filters. I love the sound, it is not too loud and has a deep sound.
