Exhaust noise after install.. video included.

Clue is that it's not there when on a lift.
I'm betting your header or mid pipe is hitting a cross member or sway bar. Mine did, before i got creative with heat and ratchet straps on the header. They're so cheaply made that they're "close to fitting" but not quite.

Now that you mention it, I did notice the mid pipe was touching one of the support arms. I was fixated on it being a leak, so I disregarded it. But I will definitely try that out. Did you basically bend the mid pipe?

I would probably pull the mid pipe before I mod it to avoid stressing the header bolts. 2 of the header bolts broke off and had to be drilled (not a fun day) so I don't want to risk the threads.

Here's a quick look at the rear end. The transmission mount arm and the midpipe are close, but there is a small gap. I'm thinking it could be the top bolt of the header-midpipe flange as well, since it's a tight fit up there.

Has the front engine mount ever been replaced? The motor might be moving enough that the exhaust is rubbing.

Yes, that was one of the first fixes I did when I got the car almost 3 years ago now. At the time there was a vibration when driving at about 3k RPM's.

The trans mounts were replaced as well about 1.5 years back when I did the clutch.
