Ive noticed this hissing noise in my s13 (ka24de all stock) .the hissing wasn't loud before but this morning when I was driving it started making a pretty loud hissing noise when I hit 3-4k rpm. The hissing went away when I let my foot off the gas and slowed down . I checked the tip of my muffler there was oil on it. So it may be an exhaust leak? Also my guiding chains are wearing off I have to change it soon. If someone can give me a definite answer that would be awesome ! Thanks
