Yes, it was me with the Mountain Dew can. It did seal great, but looked tacky. Took the stupid thing of and used a Fernco cap. Fit perfectly for me. It does not improve horse power or make the exhaust louder, but does seam to make my intake louder under a slight load. But that could also be the spiral intake spacer that was installed on it when I got it. It does make a cool whistle sound under part throttle that sounds like a BOV.
Not to change the subject, but what the hell does an throttle spacer do on a point fuel injected engine? I don't get it. I can see if it was a TBI or a carb. Or even if it was a V-MAX.
