BTB Exhausts have made our exhausts & manifold systems for many years; the design, construction & accuracy has always been to a high standard & we have been able to develop increased performance with their help. Unfortunately, in recent times many companies have appeared on the market claiming to produce systems of equal or better quality, this has caused us quite a few problems when people have bought inferior products & then found their engines don’t produce the performance that we have quoted, we have then received phone calls & emails asking us why the engines do not perform. We have found it difficult in recent times to be competitive selling the high quality BTB manifolds, so we have now asked BTB to deal direct with any customers of ours & supply the systems at the cost we would pay for a single item.

We are continuing to develop new designs of manifold to work in line with the ever increasing performance of our engine specifications. When an engine kit is purchased from us, we will supply a drawing so that the manifold can be made to suit that specification. The drawings can be purchased separately, so you can have the manifold made by a company of your choice however if it is not made exactly to our specifications, you will not get the performance.

Remember the exhaust system & manifold is as important as any other part of your engine & if it doesn’t work you will have wasted a large amount of money tuning the engine. Also don’t forget that labour is getting expensive & a good quality exhaust manifold & system do not come cheap.

*Important Note: 
If you have purchased one of our engine kits and want to achieve the full performance, you will need to have an exhaust manifold and system that matches our recommended design exactly. We have spent a considerable amount of time on the dyno, rolling road and track testing to get the designs we have developed to produce the ultimate performance. Even if you are not running our engine kits, we believe our manifold design will allow you to improve the performance of your engine, however if you have a highly tuned engine built by another engine builder, the engine design and exhaust manifold may have been specially developed by them so we suggest that you get the exhaust manifold or design from your engine builder.

For more information on exhaust systems, please see our FAQs.

The information provided in the drawing is the same information that we provide to professional exhaust system manufacturers. They are able to produce a manifold using this information to the correct length and dimensions, but will obviously need your car because they will have to design the physical layout and final shape of the manifold based on your actual car and hand build it on your car. Below is an example of the drawing you will receive.

Please provide the specification of your engine, along with the discipline you are competing in.
