New RS-RACE exhaust for the classic FD3S RX-7

GReddy Performance Products RS-Race Exhaust - 80mm cat-back

For that period-correct look and sound, the GPP RS-Race for the 1993-96 (FD3S) Mazda RX-7 is here. Styled after the legendary Power Extreme II RX-7 exhaust of the late 90’s-early 00’s, this new and improved version follows the same high-flow straight-through layout with large 80mm (3.14”) diameter mandrel-bent stainless-steel piping, but now it also incorporates superior construction, materials and precision hand-welding. The new RS-Race Tri-bolt tip feature allows for even more customization, with the installation of optional RS Tip Silencers, various tip lengths and styles in both stainless steel and genuine Titanium. We even offer optional Titanium turn-down tips, perfect for that hot rotary exhaust gases of stock and modified 13B-REW rotary engines. Relive the gold age of “Import Tuning” with the RX-7 RS-Race Exhaust!

GReddy GREX Oil Block Adapter Type E

GReddy Oil Block Adapter (Oil Cooler Kit) Campaign -  FREE Metal Label and Decal

To help clarify exactly which type of oil filter your Oil Cooler Block Adapter needs, use our FREE GReddy Metal Label and Decal in your engine bay.

If you have a GReddy Oil Block Adapter or GReddy Oil Cooler Kit, you can receive yours FREE, just follow the steps below...

(follow below...)

 1.)   Identify which type of Label you need for your correct Oil Filter Threads: 
        3/4-16UNF  or  M20xP1.5

        a.)   There are basically 3 types.   See (Figure A. below)  Compare the Center Bolt markings:
            b.)  The simplest way to identify the Oil Filter Threads from your Center Bolt is the length
              of the Threads: 
                  Short Threads 3/4-16UNF - H:13mm and Long Threads M20xP1.5 - H:20mm
        c.)   Center bolt:   Eng. 3/4-16UNF to Filter 3/4-16UNF  -  No Markings
                                     Eng. M20xP1.5  to Filter  3/4-16UNF -  Line on every corner of bolt hex
                                     Eng. M20xP1.5  to Filter M20xP1.5 -  Line around entire base (+ longer threads)
i.)  Pre-2017   The most common type of Filter Thread is the 3/4 x 16UNF - basically because all GReddy Oil Cooler Kits and Oil Block Adapters prior to 2018, all used either a center bolt adapter that was Engine: M20xP1.5 to Filter: 3/4x16UNF or Engine: 3/4x16UNF to Filter: 3/4x16UNF. 
ii.)  In 2017 GReddy introduced a new, more convenient Engine M20xP1.5 to Filter M20xP1.5 (center bolt p/n 12028813) and (oil block adapter p/n 12401119.)  Currently only newer Oil Cooler kits like the 2017-on Honda Civic Type-R and Civic Si / Sport Hatch Oil Cooler kits and new M20xP1.5 kits will come with this M20xP1.5 center bolt.
   2.)   Go to Instagram and search @greddyperformance and then "Follow" our account.
   3.)   Next take an engine bay photo(s) with your GReddy/GREX Oil Block Adapter from your
          GReddy Oil Cooler kit or your Custom Oil cooler kit, which uses a GReddy Oil Block.

   4.)   Post that photo (or photos) on your account with your Oil Filter Thread - HASHTAG:
          #GReddy3Q or #GReddyM20
  along with Tagging @greddyperformance

   5.)   We will then DM you on Instagram for your full mailing address or you can email us at
          shop@greddy.com with a link to your instagram post and  your full mailing address.

          (please be sure to let us know what size Oil Filter Threads you have:  3/4-16UNF
           or M20xP1.5) - * FREE Shipping for USA Customers / Int'l Customers, just pay shipping.

Post and Hashtag either #greddy3q or #greddym20

Designed specifically for custom applications with 2JZ engine transplants, the GReddy 2JZ Pro Surge Tank Kit offers the versatility to best match the throttle-body inlet angle and vacuum/air ports for your engine bay. This Pro kit includes 4.0l tank capacity with a large 90mm throttle-body, and top feed fuel rail, and necessary weld-on flanges. For additional rigidity during high boost applications, it uses thick 3mm formed metal tank that is welded to a precision machined, grooved base, with six individual, internal velocity-stacks. Also pre-welded are the tuned primary runners and CNC machined, intake manifold flange with fuel injector ports. Another key feature is the unique, purpose-built  fuel-resist, ring-type gaskets that seal the manifold to the head.

2JZ Pro Surge Tank Kit includes:

    Collector tank capacity 4.02 l (normal ratio 200%)
    Welding required to attach throttle body flange, throttle cable mount and air port flanges
    Surge tank, base plate and runners pre-welded
    Tuned internal velocity stacks on each runner
    Primary runner length 130㎜, OD 14.0mm ID 13.0mm
    Specially designed and manufactured O-ring style gasket provide superior manifold to head sealing for each runner
    Throttle-body hose diameter 100mm, internal butterfly diameter 90mm with low-profile throttle shaft
    Fuel Delivery tube for 14mm top feed injector (compatible with Nissan R35 VR38DETT factory injectors)

New Universal RS-Ti Muffler and Tip Sets

  No Titanium Welding Necessary!

With the included pre-welded Titanium 2-bolt flange and additional stainless-steel flange and stainless steel muffler canister mounting bracket, you do not have to be able to weld Titanium to have a custom Titanium muffler exhaust system. Just weld onto the provided stainless-steel flange and canister mounting bracket. 

GPP Universal RS-Ti Titanium Muffler and Tip sets create new lightweight options for creating your own custom full Ti or hybrid Ti/steel exhaust system. In addition to the Titanium RS Muffler canister and tip, each kit includes a stainless-steel muffler mounting-band (to weld on mounting hangers), pre-welded titanium inlet pipe and 2-bolt Ti flange, as well as a matching composite gasket and stainless-steel 2-bolt flange (to adapt the kit to steel piping.) The kits are available in a 3.0” (76mm) and 2.5” (63.5mm) piping sizes. Our signature high quality, straight-through, universal RS racing sport muffler design offers exceptional flow with a clean, yet aggressive exhaust note. And with the RS Tri-bolt removable Tip, optional RS inner tip silencers and tips can be purchased separately for even more customization.

For more details please see:
