*EDIT*
Found my answer in post #111. I think you'll want to make sure the 'hangers' used allow for some fore/aft shift as SS likes to 'grow' when it gets hot. Certain sections will see higher heat vs others so allowing movement seems to keep things happy. Just my experience/s w/the material.

Agreed. I would use hangers that offer more movement similar to how factory hangers work.

Also was hoping you would decide to run it all the way out the back....having ridden in several side exhaust cars, it sounds odd to my ears only hearing part of the 8 cyls. You will be happy having the sound and fumes at the very back of the car!

The journey for cutting the tubing was painful in the beginning. Making clean cuts on the pipe was challenging with a 6” angle grinder. Not to mention, getting the tubing cut square on the bends. Initially I wrapped painters tape around the tubing and marked them that way. Most of the time I would end up making adjustments to my cuts to get the ends to mate up properly. That was time consuming to the say the least. I then discovered the technique of using a zip tie cinched down around the tubing. You could move it however you needed along the elbow and mark it. That allowed me to get the my cuts marked perfect every time!

It was like magic!

Another trick I learned was to use a tubing cutter. I found one that would cut up to 2 5/8” on Amazon.

It helped make the cuts perfect every time! It was a little difficult once the elbow got tighter, but it worked on the 30 degree elbows with no problem. I’ll see if I have any pics of that.

Hopefully that info helps whoever would want to tackle their own exhaust.

Nice trick and cutter. Wish they made that cutter for a 3" stainless pipe.

Curious if you considered using an expansion joint and if so why you chose not to go that route. Great looking work BTW

I guess they are more commonly called flex joints. Like this one

I understand now.

I didn’t go with one since the majority of the systems I looked at did not have them. I figured between the fact the motor torques sideways and the length will be adequate enough to absorb the movement.

Someone correct me if I’m wrong pls.
