Sport muffler 1 × 60 mm for VW Golf II — TA Technix

The rear muffler determines the sound and the design of the outlet. It offers the best balance between what you spend and what you hear: with the same diameter, the body volume and baffle type distinguish a deep tone from an unpleasant resonance at 2,500 rpm on the highway.

Keeping a center muffler effectively eliminates this resonance. Removing it makes the car louder everywhere, including where you did not want it to be - this is the most common regret after an exhaust upgrade.
