1.4L & 1.6L Vauxhall Exhaust Manifolds

BTB Exhaust 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.

If you can find a manufacturer who has produced an off-the-shelf manifold that exactly matches our design, we recommend that the exhaust manifold is fitted when you initially install the engine to ensure it fits your installation correctly as fitting at a later date may mean that the off-the-shelf one may not fit. Some modifications to the shell, engine mounts, cross members and sump pan (if running wet sump) may be needed, as everyone fits engines in different positions (especially rear wheel drive) and we cannot guarantee that it will just bolt straight on. It would be impossible to us to have produced a manifold that suited every car & installation. We have made all our manifolds using a donor car that we hope is characteristic of the majority of installations.

Even if you are considering a custom made exhaust manifold and system for your car, we would recommend that you ensure you speak to the company that are manufacturing the exhaust for you before completing the installation so that there is sufficient space for the exhaust manifold and system to be made and fitted correctly.
