Exhaust Tubing

Missing a straight piece between two bends, or does a whole pipe section of your exhaust need replacing? This category brings together straight exhaust tubing in set lengths for your own project as well as ready-made pipe sections, e.g. front pipes and titanium end sections, for specific models.

Straight tubing or ready-made sections

Straight tubing is used when you build or repair an exhaust yourself. Stainless Works, for example, offers tubing in 2-foot lengths with a 1-7/8 inch diameter and 0.065 inch wall thickness, as well as 7-foot sections that you cut to size and join with exhaust bends and flanges. Ready-made sections are shaped for a specific model, e.g. Remus front pipes for the Ford Mustang 2.3L Ecoboost, Akrapovic titanium end sections for the Porsche Cayman GT4 and Mercedes-AMG G63, or Big Gun head pipes for the Honda CRF 250L. The Diamond Eye Performance brand is also available in this category.

How to choose exhaust tubing

• Diameter: It must match the rest of the system and your power goal. A bigger pipe is not automatically better – the result depends on the engine, other parts and sound requirements.
• Wall thickness: Affects weight, stiffness and how easy the tubing is to weld and bend.
• Material: Titanium is typically lighter than steel but places different demands on welding.
• Joints: Use adapters between different diameters and a flex pipe if engine movement needs to be absorbed.
• Variant: Remus front pipes are available both with and without a resonator, which typically affects the sound and the drone in the cabin.

Fitting and approval

Check the model year and engine variant before buying; Remus front pipes for the Mustang 5.0L, for example, are specified for 2017 models with a particulate filter (GPF) and Euro 6. Exhaust modifications can affect noise and emissions, so whether the car will pass inspection depends on the product and the car. Check the approval, e.g. E-mark, for the specific part number.

Frequently asked questions

Can I build my own exhaust from straight tubing?

Yes, straight tubing can be cut to size and combined with bends, flanges and adapters. This typically requires welding or clamps and precise measuring so the pipes line up and don't touch the underbody.

What is the difference between front pipes with and without a resonator?

A resonator dampens certain frequencies and can reduce drone at constant speed. Without a resonator, the sound is typically more pronounced. How big the difference is depends on the car and the rest of the exhaust.

Can a car with new exhaust pipes pass inspection?

It depends on the product and the car. Replacement can affect noise and emissions, especially if the catalytic converter or particulate filter is involved. Check the approval, e.g. E-mark, for the specific part number before fitting.
