Description:
2.5" Bönez Racing Exhaust mandrel bent downpipe for Mazda RX-7 Turbo II and 10th AE (fits any stock turbo from years 1987-1991). I used this downpipe until I purchased a full turbo-back exhaust system. This piece performs very well compared with the stock configuration and has an O2 sensor bung that fits the stock sensor. It had minor surface rust, but I thoroughly sandblasted it and painted it with black VHT ceramic paint. These sell for over $130 new and this one is excellent condition. The flanges are very sturdy, very thick steel, the sensor bung is welded solid, and the pipe itself is thick as well. This part should last a very long time and it deals with the high exhaust temperatures just fine.


CAUTION: If you are using this to replace the stock pre-catalytic converter you will most likely see an increase in boost pressure, if your intake pressure rises too high it could cause internal engine and/or turbocharger damage. If this item is the ONLY modification you have made to your stock configuration it probably will not do any harm, however I cannot be held responsible for any damages resulting from the use or misuse of this product. May or may not be legal in your area for street use.

If you happen to need one I have a couple random silicone couplers listed, too.
