APR Tuning S3 MK3 Catback Exhaust System w/o Valves & Mufflers
Vendor: APR Tuning
The APR Catback Exhaust System personalizes your vehicle exhaust system look, sound and performance. Beautifully hand-crafted T304-stainless-steel components adorn the system with stunning TIG-welding throughout. For the more track minded enthusiasts where weight, sound and price point all are highly desired metrics, the APR Valveless system is the top choice. In this configuration the axle back portion of the exhaust has the mufflers and valves removed. Weight drops considerably and the system becomes more aggressive. With the factory DP in place, the system is louder and more aggressive, but thanks to the center Helmholtz chamber, drone is reduced, giving a more pleasant, yet aggressive driving experience. However, when upgrading to the APR Race downpipe, the system transforms and becomes unapologetically raw with maximum aggression – A true track enthusiast dream.

NOTE: This system is setup without rear mufflers and exhaust valve bracketry, creating a more track-aspired exhaust volume. For standard street applications, the complete exhaust system with rear mufflers and exhaust valves may be the more suitable choice… [part# CBK0003]
