Well today out of the blue today I got 2 apex silencer inserts. They came in two different boxes, I never ordered them, and so far I don't see any odd charges on my credit card. I do have an apex exhaust (single though), but I ordered that quite a while ago.

I do have a couple of questions, are the inserts the same for the dauls as the singles? The tips are different sizes right? And also how much do they quiet the exhaust down, so far my car seems pretty quiet, running a down pipe, RB pre-silencer, to my N1, and this is on an N/A. I haven't reved past 4k so I guess there is a good chance the topend could be loud as a ****.
