One area of concern I have is your cross member clearance for your exhaust. This was an oversight when I built my car and didn't know if you had a plan yet cause it's really going to hang low......
The exhaust pipe on the right side of the pic there is bolted to the header and I did have the drivers side bolted up as well, all clears with plenty of room.
Eventually tho I think I'm gonna run TTI shorties, oval tubing exhaust and either an AAR-T/A style dynomax muffler or a spin tech muffler and side exhaust, all tucked up tight so I can slam the car and the exhaust/headers won't be the first thing to hit
