No Clamps at Header/Catalytic Converter Joints?

[pgilliam1]

So I'm under my car doing an oil change and I notice that there's no clamps where the headers go into the catalytic converters (no welds - nothing). The previous owner had RM Racing install the headers and exhaust. Is this Ok or should I clamp them (it's obviously been this way for some time)?

Picture? Stock NSX's have no clamps.

Thanks Brian. I hope these pics help and it's interesting to know that stock NSX's don't have clamps. All exhaust systems I've ever dealt with have clamps, welds or bolts at connections.
Thanks Again ---

I would imagine you would have exhaust leaks untill it warms up and seals better. Just don't warm your car up with the garage door closed! :wink:

A slip fit joint like this is common on race cars - and bikes for the matter , if done correctly (and yours look fine) it is no issue at all , in fact, clamping them may cause problems.

LOL - If I did, the leaks wouldn't matter due to ALL exhaust being trapped in the garage. But good advice just the same.

Allrighty then - no clamps! This car keeps teaching me things I thought I knew about. Thanks for the reply
