About Sleeper Designs
Sleeper Designs, LLC started as a way for Seth Ingham, owner and founder of Sleeper Designs, to make his first Toyota Supra faster.  It started in the basement garage of his parents home in 2001.  Seth skipped most the basic modifications and went straight to making a custom intake manifold and turbo system.  This started the inquires about making more intakes and has only grown from there.  The name Sleeper Designs comes from his early cars not being very attractive on the outside but very fast and pretty under the hood!  Hence the term "Sleeper" which is a car that doesn't look fast but takes everyone by surprise!  Sleeper Designs parts have gone from garage fabbed pieces to fully billet pieces of "car jewelry."  Sleeper Designs has customers all over the world and continues to grow rapidly!
