"Bees in the Can" with Cattman y-pipe? Please help...
Hi,
I just had a Cattman y-pipe installed which replaces the pre-cat. I'm now getting what I think is the "bees in the can" noise when I accelerate above 1800 rpm. It sort of sounds like a pinging noise. I cannot reproduce it in Park or Neutral when revving the engine. If I assume that the install was done correctly, is it possible the y-pipe is defective? I'm concerned because many here claim the Cattman y-pipe does not make that noise. Is it possible the noise is from a leak further downstream?
Thanks
