SP Concepts Lane Splitter Exhaust System for 2004-2013 Harley-Davidson Sportster with OEM mid controls; not compatible with forwards.

SP Concepts is known for these high-and-tight 2-into-1 Lane Splitter full exhaust systems developed for Harley-Davidson Sportster motorcycles. Like most 2-into-1 pipes, performance is key. SP systems promote exhaust velocity and do it by creating no-nonsense systems that exude beauty due to their straightforward design and unparalleled craftsmanship

  • Full stainless steel construction
  • TIG-welded
  • Header collars are machined of stainless steel
  • Hardware kit includes mount bracket, bolts, and speed nuts
  • 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

The Lane Splitter system features a 4" rolled cone muffler with 2 1/4" coiled, perforated baffle for lots of torque. You'll also be getting maximum volume from this system that's often described as the "raspy" pipe in the SP lineup. The .065" stainless steel head pipes step up from 1 3/4" and enter the muffler through a 2" stepped section. The step promotes exhaust scavenging as the exhaust rapidly expands to fill the new volume created at each step. Lane Splitter is a solid choice for unmodified engines or engines with light bolt-on power-adders up to and including a 1200 kit. The Lane Splitter has SP's shortest exhaust overall length; there's lots of bark as a result.

SP Lane Splitters also have the added benefit of helping your machine 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. 

This exhaust system does not have oxygen sensor ports. As such, the system is not compatible with motorcycles equipped with OEM fuel injection nor tuning setups (irrespective of induction method) that rely on lambda sensors placed in the exhaust stream. 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

Romance with a side of Thrill
Format: Kindle
4.25 stars! I was immediately engrossed in this debut novel, with the thrilling beginning and obvious future romance between Lou and Ava. I thought the setting of the town was wonderful, full of small charm and supportive characters. The little nods towards the continuing threat to Ava’s life were good. The budding romance was great, too! I think the intimacy scenes were soft and perfect. The main reason this didn’t reach 4.5 stars for me (thus would’ve rounded it to 5 instead of down to 4), is because of the POV switches during chapters. They’re a bit jumbled in; the reader is suddenly seeing or hearing things from Lou when it started with Ava, but then it quickly switches back to Ava. It’s not my favorite way for a story to be shared. I also lost a little steam towards the middle-end, right before the big finale. I’m not sure if my other hobby distracted me or if the story hit a slow spot. It’s possible I was hoping for a little more excitement. This story had more romance than thrill.

Blood and Muscle
Format: Kindle
I had this on my shelf for a while. lG reviews were great, the cover was pretty, and it sounded really interesting. It was better than I expected! Love when that happens🥰 The story was great, the writing was good, and the characters were amazing! Ava and Lou's chemistry at first was a little charged. But as the story went and their relationship developed, it turned into something more tender and very intimate. Throw in the witness protection thing, and you have quite exciting romance. I will be reading this again!

Thrilling Fusion of Suspense and Sapphic Longing: Blood and Muscle Delivers with Depth and Desire
Format: Kindle
Elle Alexandra delivers a masterfully woven tale of suspense and romance in Blood and Muscle, a novel that seamlessly balances pulse-pounding tension with deeply felt emotional intimacy. Set against the stark yet breathtaking backdrop of Cedar Falls, Wyoming, this story immerses readers in a world where danger and desire are inextricably linked, and where trust is both a luxury and a necessity. At the heart of the novel are Ava Bedford, a reluctant fugitive thrust into witness protection after witnessing a murder tied to a powerful political figure, and Sheriff Lou Harman, a woman whose life is defined by structure, solitude, and an unwavering sense of duty. Their dynamic is as compelling as it is electrifying, Ava’s sharp wit and warmth slowly chipping away at Lou’s carefully maintained defenses, creating a relationship that simmers with slow-burning intensity. Alexandra’s character work is nothing short of exquisite. Both Ava and Lou are richly developed, imbued with layers of vulnerability, resilience, and undeniable magnetism. Their interactions feel organic, their chemistry electric, and their individual arcs deeply satisfying. The town of Cedar Falls, too, becomes more than just a setting, it breathes with its own quiet menace and rugged charm, a place of both refuge and lurking danger. The novel’s pacing is expertly handled, with the tension mounting in a way that keeps readers perpetually on edge. Alexandra deftly balances moments of tender introspection with sequences of gripping suspense, ensuring that neither the romance nor the thriller elements overshadow the other. The prose is fluid, evocative, and often poetic, drawing readers deeper into the world she has so carefully crafted. If there is one minor drawback, it is the at-times subtle transition between the protagonists’ perspectives. While both Ava and Lou’s voices are distinct, a more clearly delineated shift in POV would have further enhanced the reading experience, offering even greater immersion into their respective inner worlds. However, this is a small quibble in an otherwise exceptional novel. Blood and Muscle is a triumph, an intoxicating blend of romance, intrigue, and raw emotion. It is a testament to the power of resilience, the fragility of trust, and the courage it takes to love in the face of uncertainty. Elle Alexandra has crafted a story that lingers long after the final page, making this a must-read for fans of sapphic fiction who crave both heart-pounding suspense and soul-stirring romance.

🩶
Format: Kindle
🩶Small town 🩶Opposites attract 🩶Sapphic romance 🩶Witness protection 🩶Sheriff/ waitress 🩶Femme/femme Ava witnesses a murder of a congressman and is forced into witness protection and relocated to Cedar falls. This is where she meets sheriff Lou. Chapter 1 had me quickly drawn in as it starts with Ava witnessing the murder after her shift. The tension was palpable. The writing was perfect. I really enjoyed this book. The crime/mystery along with the romance made the story intriguing. Lou and Ava slowly start to develop a beautiful relationship with undeniable chemistry. There is just enough angst that had me stuck wanting to know how the book was going to end. Towards the middle of the book we get Lou’s backstory which pulled at my heartstrings. She went through so much as a child which explained why she was so closed off as an adult. The spice was sweet and well written. This book gave me all the feels. It’s fun, mysterious, intense, emotional and hot. I feel so much happened in 300 pages and I still craved more. The ending was wrapped up perfectly with a HEA. Lastly, I was so happy to see chapters titles! Seems to be a rare occurrence these days.
