Customer Reviews

Everything that I experienced with your company was stress free and very easy. Ordering the exhaust parts was straightforward and no problem. They sent me my confirmation number immediately and also they sent me daily updates as to where my shipment was and when I could expect it to arrive. When I installed the exhaust everything fit and again it was not a hassle. I will tell my mechanic friends about the company and encourage them to look into it as well. I have already talked to a coworker and he told me that he had ordered some lift struts from them as well. GREAT Company to work with!
