Would have to agree with wbute, i am very happy with the note out of the single muffler twin in twin out & pacemaker extractors, I had a HZ with twin 2.5" system and 2 seperate mufflers didnt sound as good as the one i have now, and i also think the back pressure was a bit low with 2.5" twin, but that may have been the mufflers almost straight through.
