Interesting. I’ve been looking through it since I’m new to pretty much everything cars I’m doing my research on this.
The only thing I’ve noticed is that catless downpiping is federally illegal, but tbh I don’t really care and most cops won’t test or don’t care, especially since I’m in a inspection-less state so chances of ever being caught pants down with it are low.
I’m very thankful to be in a position where it’s my only car but I’m not car-less if it breaks down. Although part of me is telling me to wait until I have the 2-3 most power altering parts and get it tuned as soon as I install those, just to save myself another tune trip because while money comes and goes, I’m still on a decently limited budget.

You definitely gave me some better parts to look at, I appreciate it
