my exhaust is pretty loud, so im not sure if im just hearing things or not, but it appears to be a hissing sound at high rpms under wot. it seems like i can hear hear it from the passenger side only. Do vac leaks hiss like the way im describing? ive read about a spray test? how do you go about doing that? my idles fine, i just did 02's so i dont smell the sulfer like I used to anymore. Are there any vac lines associated with the airbox? When I did my cone filter, I may have left something unfinished, but i dont remember being a vac line on there?
