Bastuck | Valve exhaust system MSD & ESD (Cat-Back) | GR 86 & BRZ II | ECE approval

We are offering you the Bastuck flap exhaust system for your GR86/BRZ II. The system has ECE approval and is therefore legal!

For the race versions (cheaper, louder, without approval) please write to us if you are interested :)

The system is installed as a "cat-back" after the original OPF and replaces your middle and rear silencer (MSD/ESD), which results in a deep and bassy sound. Particularly compared to systems that only replace the rear silencer, the entire sound has been tuned to match. The original front silencer (with main cat and OPF) is retained.

Ordering information for wholesale goods: We would like to make it clear that this item will be sent to you directly from the wholesaler. As things stand, shipping and storage in our house would be too expensive. Regardless of this, we are the seller and liable for any defects, so it has no effect on you other than the fact that a different sender is listed on the package.

Why Bastuck?

The Bastuck system is simply the choice for you if you want legal sound on your Toyobaru. The flap control on the rear silencer allows you to cruise comfortably in town or on long journeys, with an enhanced but not intrusive sound experience (in the first half of the sound video "Drive Mode: Silent"). However, as soon as you reach 70 km/h or open the flap manually with your remote control on the race track, a sound orgy begins.

With this system you can finally legally enjoy decent sound even with the very low registered idling noise of the GR86/BRZ II. And this flap control is completely legal! The only important thing is that the remote control can only be used outside of public traffic.

But Bastuck doesn't just offer a solid sound. You also get a power increase of 5 KW and 6 NM, as you can see from the performance diagram below.

Of course, there is also a wonderful look with a duplex exhaust system with 2 diagonally cut (25°) tailpipes with a diameter of 110mm.

You can decide for yourself whether you want normal stainless steel covers or carbon covers.
