k...i just took my WSP y-pipe to get installed at a local muffler shop ( paid $60 ) ...as i was driving home...( normal ) i hear the "bees in a can" sound all the way home...it was pretty damn loud...almost as loud as my intake?...does ne 1 know if i will hear this the whole time?...that's the only problem i have right now...everything else is great...it pulls like crazy when i floor it from the line!

 

First make sure it's not rubbing on anything. Mine was pretty loud at first but has really quited down over the past few days. Give it a few days, then it should be fine, but will still have a little hum. good luck

 

The best way to quite things down is to wrap the pipe with header rap, it's the only thing that worked for my Stillen Pipe.

 

thanks...i'll wait about a week or so for it to quiet down...i'm pretty sure it's not rubbing on anything though...i'll double check
