Eliminate the costly exhaust manifold cracks prevalent in the factory exhaust manifold. The aFe BladeRunner exhaust manifold for the popular 98.5-02 5.9L Dodge Ram Cummins (24V) sets a new standard. In recent testing, this exhaust manifold outflowed the factory exhaust manifold by 50% improving performance and throttle response.

The thick wall (0.25"" vs. 0.15"") design increases strength eliminating warping and cracking. The matched ports and a merged runner design reduces exhaust backpressure, maximizing exhaust flow. Once you install this awesome exhaust manifold, you will feel improved turbo spool up times, improved throttle response and increased performance.

One-Piece Construction: This manifold is constructed out of durable stainless steel with a reinforcing rib for maximum strength along the flange and ultra-thick wall flange at the port.

All necessary hardware is included for a hassle-free installation.

Good Product But.

My overall impressions of this product was wow. Its built much better than OEM and should given its 3.5 expensive as oem. Installation was tough but I did not take off the turbo. Everything is given to you and I even got gaskets with it which is odd because they said that the kit did not come with gaskets. The manifold is not painted black as shown in the photo but has the stainless steel finish. On another not, they shipped it in a reasonable time given it was out of stock but the packaging was sub-par. The package was broken upon arrival and the exhaust manifold was exposed. Not a good sign.
