All Stainless Steel, FULL EXHAUST SYSTEMS-

Mazda RX-7

 

Download current pricelist for Mazda RX7, click here.

 

We were the exhaust manufacturer's who supplied Mazda Australia with the exhaust used on the legendary RX-7 SP both for road cars and race cars (certificate and letter from Mazda), now the time is up and we can supply the general public with what we have learnt. The stainless steel system below is what has been learnt over time and is very similar to the race system used on the 12 hour Porsche beating cars, the dump pipe in this system has been increased in diameter to 3 1/2" to extract the most from the turbo's, for the rear muffler you have a choice of titanium tip or 4' bent tip (as per the race cars) ( We have seen these systems glow red hot from turbo face to exhaust tip for 12 hours (what a sight to see). Very few, if any other, exhaust systems could withstand that).

 

FULL SYSTEM - MAZDA RX-7 (SUITS LHD AND RHD MODELS, WITH MUFFLER PLEASE SPECIFY WHICH TIP YOU REQUIRE. PARTS SOLD SEPARATELY IF REQUIRED.)

HEADER PIPE  - MAZDA RX-7

 

The header pipe has a pressed shaped section out of the turbo to allow the exhaust gases to flow and expand into the chamber to minimize the restriction we found that by then sending the gas through a 3 " pipe that noticeable gains were evident, the header pipe then is gradually tapered down at the cat end to 3" diameter to suit the same bolt pattern as the original exhaust. all from 304 stainless steel.
