Yes, thank you. The pic that way shows the post I installed to zip tie the cable extensions to.

I also asked if the full exhaust system gets a pop on upshifts or is it something to do with tuning?

I get a pop on every upshift at about 4000rpm. Just wondering what is causing it??

Cheers

That's a tune issue on the pop, can be changed with the tune. The kids intentionally make that worse for the pops and gurgle effect, in our cars here no pops.

I just purchased the FULL Ceramic Catted Street Header package that I will be installing to replace a FULL MAX Header package. In other words, I'll be replacing all parts (headers, HH mid-pipe, and SQ muffler). That may sound a little crazy, but ....

The main reason I'm doing this is because I currently have two NC Miatas (2007 and 2009). My setup is as follows:

2007 Touring, Bing Cherry, GWR Ceramic Street, HH Mid, SQ, ME CAI and Tune
2009 Sport, Silver, ME 2.5L 1.5 Cams, GWR Max, HH Mid, SQ, ME CAI and Tune, Happy Meal, AWR 1D Roll, Koyo, Ohlins, RX8 Sways

I want to replace one of them with an ND2 in the near future. So the obvious choice (in my mind) is to let go of the 2.0L and keep the 2.5L beast. But I need to tame it down a bit, for the commute. The mid-pipe on the 2009 recently developed a serious "crack" around the cat that a trusted mechanic has determined is not reparable. Thus, a full front-to-back overhaul of the exhaust with shiny new bits makes sense to me.

Anyway, my question is: How does the header install differ when swapping out a MAX header with the Street header? Will the install be any easier? Also, will the 2.5L engine necessitate any different treatment?

NOTE: I did not originally install the exhaust on either of these cars, but I'd like to give it a whirl this time around. I do enjoy wrenching just for enjoyment, though money is not a deciding factor for me. I have more experience working on my sport-touring motorcycles (BMW K1600GT and FJR1300ES), but I'm not a complete novice working on the Miatas. I've done a variety of smaller upgrades myself.

The catted headers and catless headers bolt up the same way, the only difference is what happens with the O2 sensors per the prior pages here. Fortunately 2.5 or 2.0 liter makes no difference.
