Review on DNA Motoring HDS SSAM86 Stainless Manifold by Ben Alvarez

In general a worthwhile purchase. The ports need some serious work, but the tubing used is too thin to clean as well as possible. The flange is not machined after welding and has a visible, albeit slight, misalignment. All of the internal welds look strong enough, but not pretty. I'll use it as is (with a Fel-Pro seal) and let you know if it's leaking. Edit: A few months later and I haven't had any notable problems. I applied decent low-end torque (can now rip rear wheels on gravel, wound 31-inch MTs) and got about 2mpg on the freeway. The power is better. The sound of the exhaust is excellent compared to the factory cast manifold. , Rating upgrade to 4 stars. Rig is a 1992 Geo Tracker 5sp.
