Frequently Asked Questions

What am I allowed to drive on the road?

The 90-mm symmetrical exhaust system with ECE control, the 4"-ECE exhaust system, and the 4"-TÜV downpipe. The 90-mm system without control, as well as all RACE and catless parts, are not approved for road use and are intended solely for motorsports or export.

90 mm or 4 inches—what's the difference?

The 4"-system sounds bassier and more muffled, while the 90-mm symmetrical system sounds richer. With the downpipe, both systems gain even more volume. In the sound ranking above, you can see how the character changes.

Does the exhaust system roar on the highway?

Quieter than the stock system. The 4"-system is tuned so that it doesn't rumble with either the flaps open or closed, and it's our quietest system for everyday driving. The 90-mm-system is intentionally subdued with the flaps closed to ensure a comfortable ride. In the sound ranking, you can see how the rumble compares for each setup relative to the stock system.

Can you install that?

Yes. The 4"-ECE exhaust system is available directly from HPerformance, including installation. For all other parts, just contact us.
