SP Concepts Exhausts

SP Concepts are fully focused on making the best Stainless Steel Exhausts on the market for Harley-Davidson© motorcycles.

If you’ve been following the performance V-Twin game for a while, you’ve probably noticed a growing trend towards Stainless Steel 2-into-1 Exhaust systems.

Although it’s a relatively new company, you shouldn’t worry about their experience. The two founders of SP Concepts have been in the industry for a long time, and they take great pride in the quality of their products. They don’t cut corners when it comes to fitment, finish, or manufacturing quality.

SP Concepts Exhausts are designed for Harley-Davidson M8 Softails, Baggers, Sportsters and Dyna models, and they’re now in stock & available in Australia from Rollies Speed Shop.

If you’re in the market for a Stainless Steel 2-into-1 Exhaust for your Bike, these pipes are definitely worth considering.

They’re handmade in America and come in at an affordable price.

They use solid 16 gauge wall stainless steel to make their 3-step headers, which are hand TIG welded with a brushed stainless finish. These pipes not only look great, but they also provide a noticeable boost in power over stock pipes.

The Big Bore version, in particular, has stepped headers, 1 3/4″ to 1 7/8″ to 2” at the collector, an anti-reversion chamber after the collector, and a stepped baffle of 2 1/4″ –  2 1/2”. The muffler body is 4 1/2” in diameter, all of this provides a deep, throaty tone and great power across the board.

The LaneSplitter version of the SP Concepts Exhausts also uses stepped headers, but with a single baffle of 2 1/4 inches all the way through. The muffler body is an industry standard 4 inches in diameter, which creates a similar deep tone but with a bit more raspiness. It still provides great numbers across the board, but it falls a bit shorter than the Big Bore version. It’s perfect for stock motors, but it may be limited for larger motor builds.
