when you install a mid pipe, you need to tighten the header part first, but you also must be raising the rear of the mid pipes as you tighten, otherwise they will leak.

i had that problem when i installed mine a couple days ago. i just went to fast.

jack up the middle of the h with the pipe unbolted from the catback but still bolted to the manifolds or headers (whatever you have). with the pipe still jacked up, bolt the catback evenly to the midpipe flanges. once all is tightened, let down the jack and your ready to go.
