Average Customer Review for Exhaust Manifold Elbow - Sierra
Based On 1 Review
Nice product by Chris - Ramona, CaliforniaAugust 27, 2011
I give the product itself 5 stars BUT This is actually an osco manifold with sierra sticker on the box. Nice USA made product but sierra charges more then osco direct retail price.

EXCELLENT AFTERMARKET PART by James - Hamptonville, North CarolinaSeptember 27, 2011
This elbow is far superior to the "stock" units that are no longer available. It is solid cast for as twin-wall and the bolt mating end is stainless steel!
