Hey guys, I recently had my Wsp B-pipe put on, and now, it's makes this ticking sound every now and then from the exhaust. It sounds like water dripping into an empty bucket. The performance seems good along w/ the Y-pipe, but I'm not sure if it's something I need to worry about. It's been making this noise for about a week or so whenever the car is warm. Anyone else have this noise?

I thought it was just the new B-pipe expanding and contracting with the temp changes, but the again I don't remember my Y-pipe doing this.

Thanks.
