SP Concepts Exhaust System for 2018-Up Harley-Davidson Softail (w/o OEM Bags)

SP Concepts is known for these high-and-tight 2-into-1 full exhaust systems developed for Harley-Davidson monoshock Softail motorcycles with narrow frames and no bags. Like most 2-into-1 pipes, performance is key. With differently-staged stepped head pipes and different mufflers and cores selected to match the head pipes, SP systems promote exhaust velocity by sweating the details.

  • Full stainless steel construction
  • TIG-welded
  • Header collars are machined of stainless steel
  • Accepts 12mm or 18mm oxygen sensors; adapters included
  • Hardware kit includes mount bracket, bolts, speed nuts, and adapters
  • Heat shields for this exhaust are available separately
  • Choose your finish
    • Black—satin black high temperature ceramic exhaust coating
    • Stainless—brushed and uncoated; will turn varying shades of gold with exposure to the heat of engine exhaust
    • Black Onyx—the same black ceramic coating used on the black systems, but taped to reveal exposed (raw) weld joints and resultant heat signature from the welding process
  • Choose your system length
    • Lane Splitter 
      • 4" rolled cone muffler with 2 1/4" perforated baffle for lots of torque and maximum volume that's often described as the "raspy" pipe in the SP lineup
      • .065" stainless steel head pipes step up from 1 3/4" to 1 7/8" and enter the muffler through a final 2" stepped section
      • A solid choice for unmodified engines or engines with light bolt-on power-adders
      • Shortest exhaust overall length; lots of bark as a result
    • Big Bore
      • 4 1/2" rolled cone muffler with stepped 2 1/4" to 2 1/2" perforated baffle supports the high exhaust flow of large-displacement engines
      • Best choice for highly-modified engines
      • Shortest exhaust overall length and loudest exhaust; higher compression ratios and increased displacement will both affect sound
    • Elsinore 
      • 4" rolled cone muffler with 2 1/2" performance-core perforated baffle and tone that lies somewhere between the Lane Splitter and Turnpike in terms of volume and timbre
      • Mid-length exhaust system
  • Choose your header style
    • Standard Stepped
      • .065" stainless steel head pipes step up from 1 3/4" to 1 7/8" and enter the muffler through 2" sections
    • Works Edition
      • The same construction materials and design as the Standard header, but bends are created from pie-cut sections that have been hand-TIG-welded for the competition look
    • Pro Flo
      • Anti-reversion chambers are visually stunning and highly effective
      • Dyno-proven
      • Reversion can occur when the downward stroke of the piston creates vacuum, causing exhaust pulses to be pulled in the wrong direction; this can be especially problematic with aftermarket cams that have lots of overlap

No matter what system you choose, SP pipes also shed weight when you remove your factory exhaust. And of course, the appearance is really a showstopper. People will stop to look at—and hear—your motorcycle. 

The exhaust will accept either 12mm or 18mm oxygen sensors; adapters are included so you can use either OE or aftermarket sensors as required by your tuning setup. The mounting bracket and hardware are included. Exhaust spring clips are not included; they can be purchased separately.  Exhaust gaskets are not included and should be replaced every time an exhaust system is removed; they also can be purchased separately. Heat shields for SP Concepts exhaust systems are available separately.

When picking an exhaust type, let your modifications be your guide. If you're going to stick mostly with bolt-on engine upgrades to stock engine internals, the Elsinore or Lane Splitter are the correct exhausts to select. If you're considering aggressive head work, a radical camshaft, or big increases in bore or stroke, you may want to consider the Big Bore instead. On the fence? Definitely err on the side of a smaller-bore exhaust.

Fun toy
Style: Lion Shape
Dog loved this toy. Tore hole in body to get squeaker out fairly quickly, but still played with it for a long time.

Fabric lasted less than 3 minutes. Just buy cotton rope.
Style: Monkey Shape, Style: Monkey Shape
You might as well just buy cotton rope. We should have been more careful in reading the "fine print." The description does say, "For gentlemanly dogs, it is more durable and can be used with light chewing," and "it's not indestructible dog toy." Our dog can play with one of the duck/platypus plush toys ("best seller") for months until the fabric wears through. Our expectation of more than 3 minutes from package opening to the floor being covered with stuffing was too high.

Worth it for small dogs
Style: Monkey Shape, Style: Monkey Shape
Quality is good and durable. I have a dachshund and he hasn’t ripped the squeaker out yet! The squeak is a higher pitch noise. My dog loves it. It’s nice it doubles as a tug of rope toy and a stuffy. It matched description and pictures. With all that being said if you have a bigger dog it probably won’t last long.

Sturdy Quality
Style: Cake Shape, Style: Cake Shape
These toys were perfect for my dog’s 4th birthday. You get three toys for a really reasonable price, and the quality is actually really good. He loved them right away, especially the cake toy — it makes a great crinkle sound that he can’t get enough of. They were also perfect for birthday photos. Overall, a really cute set and definitely worth it.
