Fitting 200 cell cats

Just fitted 200 cell cats to my V8V and canít get them to seal at the rear, not the gasket end. I have fitted that bit first, clamped it up but as soon as you tighten the bolts to the header/manifold a tiny gap (0.5mm) appears and it blows. I have moved the rear exhaust forward as much as possible but the gap is still there. Iím thinking of fitting an extra gasket to the front or exhaust paste, what do you think?Thanks

Double gasket? Really! You need to loosen the intermediates at the gearbox and nudge the center forward.

My brother sent me some 200 cell cats and I had the same problem. I ended up backing off all mounting HW at the mid and rear sections then use a ratchet strap to pull the section forward, tighten clamp, release strap. It worked.

Makes sense to do all the rear mounting joints. My problem is the I don't think there is any more room to pull it forward as it looks like it is butted up against body/heat shield. I'll give it a try though as it is only a tiny amount of movement to seal it.

superuser is on a distinguished road
I found that giving the h-pipe a hit of PB-blaster near at the back connection made moving it into alignment helped. With that said, on my 964 the 200cel CAT on a tiny bit too small and nothing was going to fix it, I ran a double seal for years and it never leaked.

Goodluck!
