Shanghai Jian & Mei Industry and Trade Co., Ltd. (Hereinafter referred to as JM for short) is well equipped with various multi-station cold heading machines and high-medium frequency heating machines imported from Taiwan. JM can manufacture all kinds of fasteners of various head types with the specifications from M6- M56，1/4-2”in diameter, 20-1500 (1”-60”) in length, from Class 4.8 to 12.9 and from A429 Grade 2-8. We are also capable of providing various surface surface treatment processes, including white zinc plating, blue zinc plating, yellow zinc plating, black zinc plating, blackening phosphorating, nickel plating, hot dip galvanization, DacroMat, Magni and so on. We can process carbon steel, stainless steel, aluminum and copper. According to the drawings or samples provided by customers, we will develop the optimal and cost-effective design and processing combination with cold heading, hot heading, stamping and turning so as to reduce customer’s procurement costs.
The production management of our company strictly complies with ISO9001:2008 system. All our products are subjected to strict test and inspection in each process by the workers periodically, starting from the raw materials delivered to the factory. They also receive various tests and inspections at the JM quality center before shipment. We have a variety of advanced quality testing equipment, such as tensile testing machine, hardness tester, metallographic microscope, salt spray tester and go-no go gauges etc. Each batch of exported products are identified with a unique batch number in the Finished product testing report and steel mill raw material quality inspection report.
The products passing the final inspection can be transferred for packaging. We will choose the most suitable packaging materials according to the product shape before shipment.

The Problem
It is very common for the stainless-steel exhaust manifold to crack causing exhaust gases to leak.
The stainless-steel exhaust manifolds fitted to many BMW vehicles frequently fail, often after as little as 40,000 miles, with some vehicles having 2 or 3 replaced so far. These manifolds are not suited to the conditions of the fitment and through expansion and contraction with heating /cooling eventually fail. Developing cracks or slits in the manifold causing exhaust gas leaks and the symptoms noted. These stainless-steel manifolds are simply not up to the job, BMW still offer these as replacements at a vast expense, fitting another stainless-steel manifold it would just fail again.
Symptoms of the fault
Smoke coming from under the bonnet, soot evident under the bonnet, smell of fumes – particularly when sat at idle. MOT failure for fume leak. Hissing sound or sound of gas escaping. Exhaust gas smell within vehicle cabin.
Leaking of the manifold can cause further faults such as louder engine, slower turbo response, less torque, decreased fuel economy.
To be sure of the fault it is worthwhile inspecting the exhaust manifold, using a mirror / torch it should be possible to inspect the manifold at which point cracks can usually be seen or soot / fumes can be seen.

Our solution
Install our improved design manifold for a fraction of the price of the OEM part which would just fail again.
Install our high quality cast iron manifold and cure leaks for good. Our manifold is superior in design to the BMW part, cast from tough Ductile Iron our manifold is the perfect material for the environment in which it is fitted and is suited to the wide temperature range and expansion / contraction.
Cast from solid iron with no welds or thin walls to fail. Our part has exactly the same gas flow as the OEM part, including the divider in the turbo slot so will in no way effect vehicle performance.
Our manifold has machined flange faces for a perfect fit. Supplied with the manifold is a complete fitting kit including required gaskets, bolts, studs and nuts.
A complete repair kit at a vast saving to the OEM part which would just fail again.
British company with stock ready for immediate dispatch.
Supplied with genuine gaskets and fasteners.
2 Year warranty.
Direct bolt on replacement, no modifications necessary.
