Several months ago, I had to repair a damaged stock manifold. I believed that I was removing the engine, so it seemed logical to proceed with removing the headers.
After doing extensive investigation, I have concluded that the majority of these items are of poor quality and lack value. Although LMS systems seem to have the fewest problems, the financial benefits are not significant enough to justify their use. From my perspective. I often use my automobile and wanted to ensure that anything I applied on it will withstand all weather conditions and be durable. The logical decision was to replace the original manifold.
Ultimately, I successfully replaced the right side manifold without the need to remove the engine. The price of the manifold was still 3,000 dollars, which is rather amusing.
