Looks nicely done, but I've never had luck with this type of connection. The gaskets always blew out and created an exhaust leak

I just installed mine today, later I will post dyno results and I must say the quality is nice. Wish it would have been atleast 10lbs lighter. I'll post my review on my AA in about two hours.

I had that happen once too. I personally think over-tightening cuts down on the life of those gaskets. On the other hand, I had to have my slip-fitting fabspeed tig welded because there was no way to make it stop leaking.
