Cobra El Diablo 4" 2-into-1 Full Exhaust System


Cobra's El Diablo 2-into-1 is as mean as they get, and was designed specifically for the non-touring crowd. Everyone will notice the unmistakable megaphone muffler's sound, and its unique look won't disappoint. Each system is hand-crafted for a perfect fit, right out of the box and includes provisions for attaching the OEM oxygen sensor with ease.

  • Uses equal-length exhaust headers mated to a cone-shaped megaphone muffler
  • 4" diameter PowrFlo muffler
  • 3" stepped baffle provides expected sound and power
  • Collector is one-of-a-kind that is placed in front of the footpeg
  • Massive 2-1/2" collector allows for exhaust gasses to mix, creating huge power gains
  • This design is the most efficient mating of exhaust gases to help generate more power
  • Rear cylinder header pipe runs forward and wraps around the timing cover for a sleek look
  • Improves oil dipstick clearance
  • Machined aluminum exhaust tip is powder-coated black and has an etched Cobra logo
  • Exhaust tip's reverse cone shape compliments the upswept cone muffler
  • Full-length heat shields
  • Comes with all required installation hardware and instructions
  • Made in the USA

El Diablo on Fatboy 114.

By   on  Verified Purchaser

The chrome and fit are perfect! My Fatboy is a 114 with a S&S 475 cam. Db at idle is 84-85. Runs really stronger than the Shark Road slip-ons which I did have and were really loud. At idle with the cam was 90-91 Db and the cruise was almost unbearable. Using Powervision tuner with Fuel Moto tune they provided. Now runs and sounds like a Harley. The next step will be the S&S 128 kit.


Great Deal, Great Sound, Great Quality

By   on  Verified Purchaser

This is by far the best deal for a 2-1 exhaust for a rigid mount sportster. My friend ordered a Dan Moto for his and even though that one was $70 cheaper it is half the exhaust of the Cobra. We fought and fought that dan moto and had to fab a mount for it. This one is very sturdy, sounds better, has heat shields, came with an exhaust bracket that fit perfectly.


Awesome Pipes. You Won't be Disappointed!

By   on  Verified Purchaser

Added these pipes to my 21 Harley Fat Boy. Love them! They look and sound amazing. The only thing was I had to get a c2 sensor extension for the front cylinder to be able to plug it in from the pipes.


2018 Harley Fat Bob 114 Exhaust Upgrade

By   on 

Installed on a 2018 Harley Fat Bob 114. A night and day difference in sound compared to stock. Sound bits online don't do it justice. Overall a pretty easy install with multiple videos on YouTube that you can follow. I would happily purchase again if I ever get a new bike!

Questions & Answers

Ask Question

Will this fit my 2011 heritage softail?

Yes, you would just need to select the 2011 Harley-Davidson FLSTC Heritage Softail to bring up the correct exhaust for that bike.

By Andy
Answer Question

If I install this should I have the bike tuned

Yes, it would be recommended to have the bike tuned or install a tuner along with this system.

By Andy
Answer Question

Will those pipes fit a 2018 FAT BOB. 107

Yes, that 2018 FLFB is one of the models you can choose from when checking out for these pipes.

By Andy
Answer Question

Will this fit a 2008 1200xl nightster?

Yes, that is one of the bikes that this system is offered for. Just be sure to choose that 2008 Harley Davidson XL1200N when adding to your cart.

By Andy
Answer Question

Will this fit 2018 xl1200 custom

Yes, as long as you do not have forward controls mounted on your 2018 XL1200C, you should have no problem with fitment.

By Andy
Answer Question

Does it come with plugs for cyles with out 02 sensors?

Do exhausts for all bikes have 02 sensor holes or not on older applications? Brian

For models that didn't come with O2 sensors they either won't have the O2 sensor bungs on the exhaust at all or there will be plugs.

By Andy
Answer Question

Mids

Does this work on a dyna fatbob with stock mids?

All Cobra exhausts, the El Diablos included - are test-fitted on machines equipped with the stock foot controls. If that's what you have on your machine, you should have no problem fitting this, or any other Cobra exhaust we sell, on your bike.

By Staff
Answer Question

Does this have rear peg relocation bracket

The new provided exhaust bracket has a location to install the right side passenger peg after the pipe has been installed.
