Lots of ?'s
Okay, so I want an exhaust system without the cat. I'm thinking of getting the Greddy SP2 dual cat-back system. Would it be better (better as in more power) for me to gut my cat, or actually get a nice mid-pipe? And if I did go cat-less, would it throw a CEL code? And if it does, how do you clear it permanently? Also, would I still need the O2 sensors on the exhaust if I went cat-less? That being said, would/should I need to tune anything when the whole exhaust system is installed?
Thanks in advance.
Thanks in advance.

no you dont need the o2 sensor but most midpipes have a spot for it so its best to keep it in there.
as far as power goes there isnt going to be much of a difference between gutted cat and aftermarket midpipe however there will be a big difference in sounds, Ill leave this for you to search to see what fits your needs and preferences.
As far as cel's, it almost seems like its hit or miss, I threw a cel with my turboxs system but I have a cobb ap so I was able to clear it off.
and no you would not need a tune and its not necessary however it will give you the opportunity for the most power if you do tune the car (200 dollar service from mm with a cobb ap or buy the ap from him for 500 and get a free tune).

Okay. Another set of ?'s. I was going to get a AP Under-drive Pulley with the belt. There's a set of pulleys for the 8 on rx7store.net. Which one would be better to get (power wise). Also, is there any A/C delete kit made for the 8? I have an 04'.

The best way to search this forum:
RX-8 Club has tons of information on hand. And I mean tons. Literally. Add up the weight of everyone's brain, and it will be several tons. Sorry, I know that was bad.
Collectively, we know more than any one dealership, tech, repair shop, or spec manual. However, as usual, the information doesn't all sit in one place, it doesn't sit in one head, and we have our idiots, our morons, our ********, our kids, our jerks, and our literary incompetents. Just like any forum. Fortunately, we have relatively fewer of those than most other car communities out there. But they still exist.
We also have a Search button, and a Search function for the board, but it isn't very good. It removes words that it sees as common or too short, but are a critical part of the search. It doesn't allow for search by relevancy, as in real relevancy. You mostly have to do alot of hunting and pecking in the search results to come up with what you might be looking for.
Add the two above issues together, and you can easily take all day to find only bad information.
But I have good news! You can improve your results and search speed by up to 15% by switching to Google!
As in Google.com.
Go to Google.com, and in the search box, type: site:rx8club.com
Then a space.
Then start typing what you are looking for.
Like this:
RX8Club.com search via Google
Your Google search results will be ONLY from this forum, and it will use all the power and intelligence of the best search engine in the world.
I still use that function nearly every day between RX8Club.com, Miata.net, and Mazdas247.com. So if you have a question that you think is common, give that search method a try, sit back with your beverage of choice and start reading
Additional Google Search tip:
If you are trying to search within a specific thread for information threads that turn out to be very long, add the name of the thread to your search in quotes. This will not restrict the search to just that thread, however the results from that thread will be bias'ed towards the top of the Google search results, and usually be the first results.
