True Equal Length Exhausts

The equal-length primaries ensure that the exhaust gases flow alternately through the collector, resulting in less backpressure than with an unequal-length header.

Due to the free flow, a higher velocity of the gases is achieved, causing a negative pulse behind the pressure wave. This pulse helps to empty the cylinder and will create a vacuum in the cylinder, which can then be filled more easily by the air-fuel mixture.

The result is a more efficient engine that can work freely and is unrestricted, increasing horsepower. This is also the main reason why just about any engine can see immediate performance gains when swapping out your current manifold for an equal length Celeritech header.

At Celeritech we ensure unparalleled perfection in all areas of our high performance exhaust systems.

- All bends are cut 100% perpendicular to the centerline to maximize the flow characteristics of the pipes
- All bends are purge welded for a smooth surface on the inside of the headers and exhausts.
- We work with in-house made high flow collectors to ensure minimal obstruction and maximum performance.

All these points and more ensure an optimally functioning engine.

A precise answer to the question of how much more power you get from your engine by using our exhaust manifolds cannot be given in numbers without extensive testing on dynos. But experience shows that due to our perfection, all customers are extremely satisfied with the results.

We dare to say that we can make sure your engine runs better than ever before with a Celeritech exhaust system.

If you use Celeritech's Custom Service, there is the option to stay up to date via videos during the design process. Do you want a completely unique exhaust manifold, does it have to look a particular way, does it have to have a certain length, does it have to be desired diameter? Everything is negotiable.

Our motto is: "We are only limeted by space!"

So, Yes you are welcome to participate in the design to create the best sollution for your project.

Replicating an original exhaust is not always easy, because every exhaust has unique properties.

At Celeritech we offer the possibility to make an exhaust look like the original. Although we cannot always ignore the urge to improve the original on small points.

Do you have a specific wish and are you curious if we can imitate your exhaust, do not hesitate to contact us.

The production time of a Celeritech exhaust system depends on the complexity of the project. On average you can assume a production time between 4 to 8 weeks excluding the time for designing.

If the car is not in our database jet, we have to make a 3D scan at the preferred location of the customer. So there is no transport needed. We come to you! One day is all we need.
