Question:

I decided to have an exhaust manifold and system made, unfortunately your recommended manufacturer was too expensive, so I choose another supplier whose price was more affordable. When the car was finished, the exhaust system looked fantastic and the welding was excellent, unfortunately when it was put on the rolling road the performance did not match what I was expecting. The guys running the rolling road said the engine was performing unusually and believed it was something to do with the exhaust manifold. What can I do?

Answer:

I would check your exhaust manifold dimensions very carefully to ensure all the pipes are equal and the correct length, if they are not, which is quite likely then the contact the manufacturer and see what they are prepared to do for you. Hopefully they will sort the issues out for you, unfortunately the difference between a cheap exhaust manifold and a manifold made to the correct dimensions can take 4 or 5 times longer to manufacture and it is only when you come to measure the manifold itself after an issue has arisen, that this problem is discovered. We have investigated in the past, cheaper alternatives but have always been let down and as the old saying goes you only get what you pay for.
