Just ordered two 3" flex pipes, a 3" 304 SS exhaust pipe kit, a 3" x-pipe, and a 3" dual inlet dual outlet Magnaflow muffler. Gonna try and build an exhaust next weekend if its not sub 32 outside. Plan is to attach the flex pipes to the header collectors. Merge those as far forward as possible into the x-pipe, run two short lengths of pipe into the muffler, and then dump the muffler somewhere before the rear diff.

I think it'll just dump for now. In the future if I wanna add a rear section and some tips, I'll do it. For now, the more racecar the better. I thought the G was gonna be my daily but I think she's going to turn more into a weekend warrior. I will not be installing A/C and the car doesn't have cruise control. Trying to daily a car without A/C in Florida is a no-no in my book. Might think about a rear seat delete, a harness bar, and some new seats in the near future.

Started building the exhaust today. There is not a lot of room under these cars to run exhaust piping. One problem may be because I am laying on my back and at the mercy of how high my jack stands can go - it would be so nice to have a lift. The Magnaflow 3" dual inlet/dual outlet is way too long and too tall to fit anywhere underneath the G. This was my first time welding anything other than just some scrap pieces of metal together. My welds are not very pretty but they seem structurally sound. I used solar flux on the backside to avoid the "sugaring" that comes from a non-shielded TIG weld.
Today I completed - 2 V-bands welded onto the flex pipe sections, modified the x-pipe to make it narrower to fit fit in the transmission tunnel, and finished up the passenger side header to x-pipe connection.
It's too dark to take any pictures now but I will try and get some before I start working on it again in the next few days.
I just ordered 2 Dynomax mini bullet race mufflers. These will take the place of the gigantic Magnaflow that I had planned. It's going to be quite a bit louder but at least won't be as loud as open headers.

TIG ?
Best advice I can give is to fold up a little piece of fire blanket so you can rest your hand on it directly next to what you're welding. It's all about that steady hand so you can keep the tip at the proper distance. If you are not supported properly then the distance fluctuates and you lose control of the puddle.
WATCH THE PUDDLE, don't watch the tip. Don't dip the tip into the puddle or you have to grind it down, you'll know if you do because it changes color and starts popping. Just watch the puddle and add fill rod as needed to keep the size consistent.

I also wish I had a chop saw or band saw. I am having to make all of my cuts with a 4.5" angle grinder. I'm using a hose clamp as a guide to make sure I get a straight cutting line, tracing that line with a sharpie, then free handing with the grinder. Not the most ideal setup but it's working - a little.
