Replaced the header gaskets with fel-pro 1406s and they seal great. Since my Random Tech Y pipe is an easy unbolt, I took a little blast through town with open headers. Yikes, it's been a while since I did that.

I've only heard mine at idle and low RPMs though...I can't even imagine what it sounds like at 6k, like you experienced
