Hi guys!

I have a question, namely:

I have a Greddy SP2 system and I now have a 200 cell High Flow Cat installed. Now it is so we have in Austria, unfortunately have very strict laws here and the system too loud has become.

Have measured 108 dB, which is quite fierce.

Now I do not know what I do. The High Flow Cat was so constructed because the original was defective.

Anyone knows are there for the Greddy SP2 a silencer?
Or would exhaust valve like this:



make a difference by the volume? The manufacturer writes "massive volumes" reduction.
But is such a flap will not play bad for performance?

Thank you for the help!

Regards
Peter

PS: Sorry the bad english, i have it translate with the google translater.

The Greddy SP2 is just loud in general. That exhaust thing may work. I have never seen it as well. Sorry I couldn't help much but I'm part Austrian ahah
