First of all, All our products need assembling.

Although we do long term tests on our exhaust systems to find out any mechanical issues,

Kreissieg holds no responsibility on any engine, emission and other exhaust related engine/drivetrain failures.

This is because of difference of each car's condition and different equipment/environments that each car encounters.

Our systems are designed to use “off-road” only.

Please check your local laws regarding the use on any parts.
