Is there anyway you can fix the Bees in a can sound? I have just installed my Stillen y-pipe and it sounds nasty. It starts around 1500-2000 rpms. Then goes away around 4600. can someone that gad this problem give me a solution?

 

I don't know what bee's in a can sound like but on my auto with a WSP y-pipe it would rattle underneath the shifter everytime I got on it hard. Making a long diagnoses short it was the heat shield that is located right around the flex section.
If you are auto look under your car and imagine that the Y-pipe needs about an inch or too of clearance (because it does move quite a bit) bend everything that conflicts with this out of the way. Look around the flex section, that's where mine was rubbing. Good luck and keep me posted.

 

Can that bees in a can sound ruin performance? I get that rattle when its cold and I always thought it was the cat. I can feel a loss of acceleration. This is with the stock Y-pipe

 

Your problem sounds like the ignition coils. There is a TSB for them.
