Exhaust Install

[Stpman]

Finally get time to get back at the Vette and take a serious run at gtting it back togther to enjoy. Today I worked on the drivers side exhaust from the collector back through the trans crossmember.
What do you guys think does this look right?

Looking good, are you going to fab it completely w/ the body off? I'd be worries that you might run into clearance issues. To the X member is as far as I would go and do the rest while the body is on there.

The plan was to fab it all and use a section of floor pan (front of the doors back to the bumper) from a 74 I parted out. I have band clamps for behind the crossmember and I have to check clearances between the "X" and the parking brake cable.

I was wondering about the pipe running down away from the collector the way it does.

The exhaust is awfully close to the drivers side floor. It will probably be fine, but I would have done it with the body on. Then again, it's not so easy without a lift.

Looks good.
I use the band clamps behind the xmember too. Makes it super easy to drop the exhaust for access.
The butyl goo that comes with them new works great, but makes a hell of a mess and doesn't seal leaks the next time. I ended up wrapping the pipe a bit first with fiberglass mat and then the clamps, no leaks and grips well.

I got pissed off over all the exhausting/cross support problems on my OEM Muncie '72.....

so with the 700 conversion, I cut the cross member, and fashioned a method of install with two bolts facing fore/aft....

but with several R&R's over the years I got good and pissed this last time around...and had the OEM cross member cut out on the bottom of the pipe loops, and nice/wide on the frame bottom ends...so it essentially is a wide V upside down...rounded on top per stock....
then to build a bridge/truss type lattice in the top of it for strength...

and run the exhaust nice and clean under the entire support....

trick is...I have a welder buddy, second is....it has to be done at HIS house....he not moving that machine, and I don't blame him....

and without his help, NONE of these extensive steel projects would be possible...rack, crossmember, front grill, induction, and a few others...

:harhar::thankyou:

Got the pass side mocked up today




A little more tweaking and it's ready to weld

Look'in good, I have to say it's so much easier placing tack welds from uptop rather then underneath at about 18" off the floor. Especially with a welding helmet to work around.
