I have had DIN mount gauges in my car for nearly 15 years. I never had any problem taking a quick glance at my boost gauge to see what its doing. Some tasks are too difficult for impaired people. You should probably stick to something easier.... Dipshit!!!

sold--no longer in debt
The butt hurt statement sounds like the voice of experience. Maybe you should carry a cushion around with you.

That's cute.

Factory Y-Pipe out and easy access to downpipe. Letting the bolts soak for a day the hitting them again and letting them soak. Probably take the downpipe off Saturday.
Happy I changed out the y-pipe because I had a coolant hose ready to blow. You can see in the picture that has the end of the socket wrench touching it.

Definitely wouldn't use off-the-shelf hose unless it is high temp especially that close to the turbo.

If it hasn't been mentioned there is an updated version of the coolant hoses with a more heat resistant reinforcement braid (probably Nomex or similar vs standard Nylon). I bought the coolant hose kit from Malloy Mazda when I did my rebuild. They probably still offer it.

Thanks will look into that.

I could not wait 
. All nuts came off clean except one. Stud came out on the first one but it was clean. With all the so called horror stories about these nuts and downpipe....seems like an easy upgrade for me that just takes a little time.

Well dang nut on the stud on the main cat will not break!!!!! I have soaked and soaked and soaked...heated and heated and heated. Last resort is a nut cracker.

I am officially beat!!!!! Started cutting it and that did not work, and I bet a nut splitter would not have either. Guessing I am going to have to curt the whole stud off. Any suggestion prior to me doing this? Will wait an hour for a reply

What did you use to heat it? You need to get that thing super hot when it’s good and stuck. I’ve used a map gas torch before which is hotter than propane and it didn’t work. Then I got the oxy/acetylene rig out and that was able to loosen it. Of course it would have cut it off had I chose to go that route. Good luck

I know I do not need a mid pipe but with this all off I probably will just do a high flow cat and watch the boost while driving until I get a boost controller. Not 100%...so do not go crazy guys because I am probably going to put the stock cat back on.
I know I put the cart before the horse on this one. Will send the downpipe out to get coated, get coolant hose, get lines for new y-pipe that broke, get gaskets, and debate on new cat. Mainly did this first so that I would not keep driving it over the winter

I have that Racing Beat exhaust on mine. It's really nice and I'll probably never change it. It's the best sounding exhaust and looks pretty much stock. Also less worry about it scraping like big fart cans can.
I don't know if it really changes the AFR (aren't there sensors for that?), but reducing exhaust backpressure does change the point (as in, how high RPMs get) at which delta engine pressure goes from negative to positive which does change overlap, and rotaries like having a little overlap.
Afaik, the "liking overlap" comes down to helping cool the engine and reducing knock, and I'm not sure about any effect on AFR.
Ideally, you'd have a restrictor that closes up at lower RPMs in these cars to increase exhaust pressure, and thus exhaust manifold pressure, and thus keep engine pressure delta positive at lower RPMs while opening up at higher RPMs. I think those improve spool times as well.
So yeah. I'd agree on not getting too high flowing of an exhaust, and not removing precat with the stock ECU.
