When I needed an Automotive exhaust manifold, I purchased this one. After I put it to the test, I found that it was easy to install and worked exceptionally well .The exhaust NOTE has gotten louder and deeper giving my Jeep a more aggressive stance. The pros of this product are that it significantly improves the performance of my Jeep's exhaust system, and it is a direct replacement that makes the installation a breeze. The only con is that it is slightly expensive for a replacement part. OveralSee full review
