So I have the TRD exhaust/sport muffler on my xB but it is too quiet. After investigating I see there is still another factory muffler in place. So my question to you guys and girls is where can I find a midsection pipe to be able to eliminate that other factory muffler? That is if they have anything out there like that. I do feel that if I am successful at finding this I will probably get the sound that I am looking for.
