By reducing the backpressure just aft of the turbo, this unit helps improve boost response on your SR-equipped 240SX.
Utilizing a larger piping diameter (73.2mm vs. 65mm on the OE unit) and a lighter weight (2.84 lbs. vs. 4.73 lbs. for the OE unit) this inexpensive unit pays BIG dividends.
Smooth internal finish improves exhaust flow over the rough-walled, cast iron OE piece.
Whether used alone or in conjunction with the EXPREME Manifold, the Tomei turbo elbow will help maximize the potential of any turbo that you have bolted to your S13, S14, or S15 SR20DET!
