I’ve been thinking of reracking my exhaust some and dropping the muffler. I don’t make boost quite as early/quickly as I would like to. I’m hypothesizing that the bend I had to put in the exhaust between the cat and the muffler, coupled with the turbo flange being flush mounted to the pipe is causing a fair amount of turbulent flow and now allowing the turbo to spool up as quickly as it could with a faster flow.

If I lose the muffler I can push the turbo back and up some (the undercarriage gains a lot of height when you move back a little closer to axle) and use a straight pipe to 90 degree elbow like I had originally planned on doing.
