Stainless Powered Concepts (SPC)

Mufflers by Stainless Powered Concepts 

A new entrant to the aftermarket exhaust segment is Lake Elsinore, California based Stainless Powered Concepts (SPC) - founded in May this year by Mark Jacobs and Greg Miranda, two industry professionals with long standing roots in the exhaust space.  Mark and Greg are the former President and Sales Manager respectively at Two Brothers Racing. 

Speaking with AMD, Mark said "we realized that it was time for us to move on and pave our own way in the exhausts market. We were no longer having fun, and when that happens, it is best for all concerned to change things up.

'Big Bore'

"We fully understood that starting something new would come with many challenges, loaded with uncertainty, but the relationships that we had developed over many years have made this transition amazing.

"Our business philosophy is old school. To deliver one-on-one service to our dealers and end users, use only the best materials, create something that you would be proud to put on your own bike and understand the difference between knowing what to do and what not to do!"


Their initial product applications include M-8 Softails and Baggers, Twin Cam Baggers and 2006 - 2016 Dyna models. Initially, SPC has three muffler designs - 'Lanesplitter', 'Cutback' and 'Big Bore'.

"We construct our mufflers with hand tig-welded stepped headers for maximum torque. Our systems will include the necessary hardware for simple installation, as well as 02 sensors for both stock and wideband applications.  


"Our flagship Big Bore design includes a 4.5" cone with 2.25" to 2.5" stepped core. The end result is a perfect blend of sound, performance and look."
