Question 1

What is included in a sport muffler kit?

Accepted Answer

A complete kit includes: sport rear muffler, connection pipes, mounting clamps, gaskets and sport exhaust tip. Some kits also include intermediate muffler. All components are manufactured in high-quality stainless steel for maximum durability.

Question 2

Are sport muffler kits type-approved?

Accepted Answer

Yes, our sport muffler kits comply with European type-approval regulations (E-Mark) and pass MOT tests. They include catalytic converter and respect noise (74 dB maximum) and emissions limits. Non-approved kits are not legal and may be rejected at technical inspection.

Question 3

How much power does the engine gain with a sport exhaust?

Accepted Answer

It depends on the vehicle and engine, but generally between 5-15 HP in naturally aspirated petrol engines. In turbo engines, the gain can be higher (10-25 HP) especially if combined with remapping. The main benefit is the improved sporty sound and weight reduction.

Question 4

Is it difficult to install a sport exhaust kit?

Accepted Answer

Installation is relatively simple if you have mechanical experience and basic tools (lift or ramps, wrenches). The original exhaust is removed from the manifold or catalytic converter and the new one is installed by tightening the clamps. Estimated time: 2-4 hours. We recommend workshop installation for warranty.

Question 5

Does the sport exhaust increase fuel consumption?

Accepted Answer

Not necessarily. A well-designed sport exhaust reduces back pressure improving gas evacuation, which can slightly improve efficiency. However, the sporty sound may encourage more aggressive driving, thus increasing consumption. In normal driving, consumption is similar to original.
