Product Information

The 360 Flatline Sportster Exhaust blends bold design with performance-focused engineering.

Its signature layout combines a full wrap-around 360° lower pipe with a straight lateral upper pipe, creating a seamless, level visual line from front to rear.

This 2-into-1 configuration improves exhaust scavenging, throttle response, and overall power delivery while producing a deep, resonant exhaust tone.

Handcrafted from mandrel-bent 304 stainless steel and fully TIG welded, the system delivers superior durability and corrosion resistance.

Internally ceramic-coated tubing reduces radiant heat, while fiberglass-packed resonated mufflers balance aggressive sound with ride comfort.

Optional O2 bungs support EFI Sportsters, and the integrated flange kit removes OEM snap-ring hardware for a cleaner, stronger installation.

What Our Customers Say

Really happy with the product. Took a while to get my order but they were out of the spark plug cables I ordered. I had to email and inquire what the deal was. They were super helpful once I initiated communication. Would have been cool to get some swag or something since they took so long. But the relocator is great. I really love it. And they responded promptly once I reached out to them. Their customer service is truly fantastic.

Brian Hopkins
Ignition Coils Relocator (L.E.) Relocator for Harley-Davidson Sportster

I had some questions on some bars, so I DMd them on Instagram. The dude I talked to was super helpful. I purchased the shirt because of his response. I’ll rep the brand due to the customer service.
