I used to have a black 98 trans am. I used to drool over the sunset orange metallic ones. Guess im making up for what I couldn't have before lmao.

I acquired a Meisterschaft GTHaus SGT exhaust with the LMR midpipes.

They took away the center jackpoint on the f90. I had to come up with a way to get the car in the air.

I made a set of car stands. They are stackable so I can put the car up higher in a series of steps. Small one, then the bigger one, then both of them together. This way I didn't have to jack the car up extremely uneven(dont want any new rattles or creaking).

These worked out very well but they took me a few days to make.

The stock exhaust removal was a bit challenging solo. I got creative and I was able to drop it down and drag it out by supporting it with a ramp/wood on one side and my jack on the other side.

Installation was a bit time consuming to get right. I had to adjust it alot. You start from the downpipes and work your way back, leaving everything loose at first. And then start from the front and tighten clamps and hangers as you go.

Pro tip: support the X-pipe with a jack a tad bit higher than where it will naturally hang. Tighten everything up while its supported, front to back. This will help take the slack out of the exhaust and make it easier to position and more rigid.

I added a couple washers under the tunnel brace because the midpipes were barely touching. Problem solved.

You are running the mini rear muffler or the bypass pipe? Looks good and I like the DIY.

I did the little muffler. Not sure how much of a difference the straight pipe would make. Ill probably do downpipes in the future so I figured the quieter option would be better.
