My stock h has been laying against my wall in my garage for 5 years. Still OK to put on? I got tired of the black bumper and smell. Sound is incredible though.
Sure but why not add some high flow cats, I have the same setup with super 44's in slp tubing. I got some 200 core high flow cats on the way to give back some torque I lost. Anyways...It should be fine, whatever is in there should burn up and come out
