proper way to install the 3 bolt collector

338 Views 6 Replies 5 Participants Last post by  RickSBC400
Hello,

I bought these and the 3 bolt collector part is not welded onto the pipe. Do I need to weld those on or is it ok if they are loose and just bolt up? Will the gasket be enough to have a complete seal between the 2 flanges or do I need to have the flanges welded on? I have an 02 sensor that I'm sensitive about having any exhaust leaks so that is what I'm concerned with.


Thanks,
Rick

I would weld them on.

Don't know how good that gasket is. I make all my own, never a leak or blow out. Never loose header bolts either.

Looks like I was making that same gasket at some point:

Weld or slip fit and clamp to the pipe. Use the flange gaskets and bolts but copper gaskets will last longer. Orient a flat side on the bottom for more ground clearance.

If you are saying the 3 bolt flange ring spins on the reducer, I have never welded the ring to the pipe. Weld the reducer to your rear exhaust and bolt the flanges together.
