Can RP weld a reasonator in as well? i dont mind paying extra for it. Just dont want it to be too loud.

im interested, is it capable with the greddy sp2 exhaust?

yes it is, i think it gained 8 hp with the sp2 exhaust... =)

Yes they can. Once this goes through, call them up and talk to Chris. He should be able to set you up.

I'm in!

Yes, I am in!

Count on me!

Anybody know what hp/tq gains are seen with otherwise stock exhaust?

this answers both of your questions...

I called RP and they said that as long as the aftermarket exhaust bolts up fine to the OEM cat pipe, then there should be no issues at all, as the fitments are designed to be the same as the OEM pipe.

Ok...I am in then.

imrtommy:
What I meant about “CAD” speaking with the HKS question is that most all manufactures exhaust come with the mid-pipe and it is design to marry up to the OEM TWC/Three-Way Catalyst or “Cat-Pipe”. So in the broadest terms… it stands to reason that the answer is yes. By nature if your exhaust mated up with the OEM TWC than you should have no issues with RP’s Sup-Cat. Chris did mention some people noted a clearance issue, but he said he would provide a visual fix incase anyone ran into it for some reason.
Also see the attached image for a diagram of the OEM exhaust system from the Exhaust Manifold back

\\Konig\\:
I know they do accept PayPal so I do not think it will be an issue, but that is one of the questions I am waiting on. I do think they will accept it as a method of payment though.

CoupeM:
I understand that they do Custom Fabrication in shop so I would guess for a few extra bucks the answer is probably yes. I would think this goes for the Clamp/Hanger too. Chris noted that it was not guaranteed to be on the GB Sup-Cats but if you must have one I am sure you can request to pay and have it included. Also, most all muffler shops around the world can do this for you after the fact for near nothing in cost too.

Rhythmic:
Please do not hold me to this, but if I recall it is claimed to be about an 8-12 HP gain. Not a whole helluva lot, but most honest manufacturers will tell you that Mazda Engineering on this motor and car had already damn near squeezed every last drop of performance they could without going Turbo or Supercharged.

Creto:
Thanks again for doing your leg work with RP… I hope they are not getting annoyed with you asking them for answers to these questions. I am guessing they are not. If you call them again… maybe you will want to let them know the count already… 15 in 24hrs is not bad at all.

Im in as well...

Sorry...one more question...does this version have a heat sheild?

Oh no! The list is filling up!

How long are you going to be letting people put their names on the list?

I'll know by tomorrow if I'm in or not.

I think you will be safe...
I am waiting for a reply on how many units or when the Buy will end. I am fairly sure the will let up to 50 units go.
Rhythmic:
I will have to ask and get back to you on that. I do not know.

Question.

Should this GB wait until they get everything on it that the masses want and that RP has the intention of doing in the future anyways?

We'll save $45 but it won't have the hanger that everyone says is necessary or the revised clamp "that isn't at the top of their list". I thought I read some where that it cost someone $65-70 to have a hanger removed from the oem cat and then welded onto the new cat. Am I mistaken with that comment? That would neglect any savings, correct?

I was on the original list that was interested and still am but I'm just wondering if this is just getting rushed for the sake of rushing it. When it might be better to wait until this piece has everything that it plans on having in the future.

Is this valid or am I missing something?

I'm in if this is the newer revised higher flowing RP super cat???

Id want mine with a hanger, but if this is the newer higher flowing RP super cat im IN :o)
when do we know when we have to pay and stuff? thanks :o)

The hanger/clamp is not necessary. Only some people have reported an issue with the lack of hanger, and those that have gotten one put on, said that places like Meineke will do it for about $10 (may have to shop around a little, but it's not a big price). Also, as was noted in the original post, there will be included instructions that will also assist in preventing any scraping issues.

Here are some Answers to past questions...

1.) Does this cat have a heat shield?
Yes it does have a heat shield on top. The picture on the website is not current. I have seen quite a few pictures of it on the forum. If a good, clear and current picture is needed, it can be provided.

2.) Is this the New Higher-flowing more opened mesh version you all were working on?
This is the newer, freer flowing unit (not that the old one was an issue). The active metals content is even higher than before (platinum, palladium and rhodium)

3.) Can buyers opt to have the Hanger or resonators added to their cat prior to shipping?
a.) Do you have a flat rate for Hanger Service?
As of now, we do not have a shippable hanger solution. We will, but not right now. It is a bolt on hanger and can be added in the future. The subframe realignment has been effective in avoiding pipe to brace interference.
b.) Do you have a flat rate for Resonator Service?
We do have a stainless resonator that can be added, if desired. It is the same unit we use on the midpipe. This adds $80 to the total and is not a normally stocked item, but would not be an issue to produce.

4.) What are your rough claims of HP gains with this current Cat?
HP has been tested many times. We've seen as much as 15HP improvement and as little as 9HP. About 12HP is what we tell everyone is realistic.

5.) Will you all accept PayPal payments too?
Yes we do accept paypal. The address we use is paypal@rx7.com

just wondering would it be best i take this to a muffler shop for install or should i try doing it on m own?

If you have jack stands, a Jack, some basic tools, a friend & some balls... You can do it your self. Friend and Balls are not even required just makes it more interesting!!! :eek:

Do not attempt this right after driving the car for 40 miles.
Unless you have some welding gloves,,, :eek:
The exhaust will be HOT, DAMN, HOT !

so tempting!! hope i can save up enough money by the time you guys start paying

Screw it. I'm in!


I CAN'T WAIT!
