Hi,
Not sure where to post this question, but this seems as good a spot as any...

Folks, bounce
Can a rear exhaust manifold be replaced without removing the engine? ('98 Riv)
My recently replaced engine has a manifold that exits to the downpipe too far to the left, causing the DP to rub against the power steering lines and offsetting the entire front portion of the exhaust system a couple of inches.
I've found a manifold from a Lesabre that exits more to the right. Seems correct.
This was an unexpected problem. I bought this engine about 9 years ago and am just getting to this project. For the life of me, I can't remember what GM vehicle this L67 came from.
So, can this be replaced without moving the engine, and further, how did this happen?
Any input welcome and much appreciated.
Thanks!

Yes it can! Will be the best time you will completely NOT enjoy!

The only way, is to remove your existing downpipe, with a steady hand, the rights swivels and extensions, plenty of light, CBD/beer, and LUCK you can get it done without removing that pesky engine!

I salute you sir!

Can you get to the rear manifold easier from the bottom, with the car on ramps or jackstands?

Yes you can. Honestly that's about the ONLY way I have ever seen it being able to be done if you had no other option. You have virtually 0 visibility from the top engine bay.

Removing your down pipe helps tremendously.
