The stock silencer or catback exhaust system with part number 4T0.251.051.F is a special exhaust for country like China to meet higher emission standard. This exhaust has four massive OPF/GPF/PPF thus resulting a very quiet exhaust sound, I choose to delete these four filters, here is my exhaust video after modifications, the volume of the sound and the pitch of the exhaust are finally recovered. This exhaust is a chamber muffler design and piping is much longer when valves are opened, so the exhaust sound pitch is much higher compared to the stock EVO non gpf version.

BTW, I am based in Shanghai China, please contact me if you are also in Shanghai I wish this information might be helpful

Also, when the exhaust valves are opened, due to chamber muffler design, the exhaust flow still need to go through the muffler, it generates a special sound effect between 4000-5000 rpm, I feel the sweet drone at this rpm range actually multiply the sound volume, it make people feel like the car is in the tunnels

Both literally and figuratively that sounds great! Enjoy!

Sounds as it should. When you see cops just put in strada. That's what I do.

Sounds awesome. What exhaust system did you add?

 

[ULTIMATEPD]

What did you do to eliminate the check engine light on the dash, since the OPF system has sensors etc.

How does this compare to the stock exhaust in the US or Europe?
