First I gotta thank MaxType 240 (Jesse) and Jeff240sx (Jeff,) because with out their help this couldn't get done. 4 hours laters my hot shot headers and b&m shifter are finally installed, the joy! However, I'm getting this pulsing noise from my headers and we both believe is because we didn't tighten the bolts enough because of the welds weren't fine enough to tighten completely.

Could it be something else giving that pulsing sound? If this is the culprit can anyone recommend a mechanic to simply grind down the welds and tighten a couple bolts. Something that would only take him 30 minutes or so to do? If not, i'm going to hit the yellow pages.
