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

We're offering you the "simple" exhaust system without a valve from Bastuck for your GR86/BRZ II. The system is ECE-approved and therefore legal!

For the race versions (cheaper, louder, without approval) please write to us if you are interested :) for the version with flap click here.

The system is a "cat-back" system installed after the original OPF, thus replacing your mid- and rear mufflers (MDF/ESD), resulting in a deep, bassy sound. This is especially true compared to systems that only replace the rear muffler, as the entire sound is tuned to match the original sound. The original front muffler (with main catalytic converter and OPF) remains intact.

Why Bastuck?

With the Bastuck system, you can finally get more sound into your car. The system is designed to give you a deeper and louder sound without exceeding the applicable limits and always staying within the legal range. A true feast for the ears, because it doesn't just roar; it actually sounds great.

But Bastuck doesn't just deliver a solid sound. You also get a power increase of 5 kW and 6 Nm, as you can see from the performance chart 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.

The "normal" system is only available with stainless steel panels.
