I actually had exhaust at one point, but it to be honest it did not sound good at all for my engine. I had a si/do 24" magnaflow, and in my opinion it was the best sounding for the v6, but with mostly driving highway miles I had something quieter installed because of the drone. After the magnaflow, the shop put on a beast muffler that is much quieter, but it seems to actually have very good airflow. It actually feels faster which is weird. I don't rly plan to tamper with the actual muffler any more, already wasted way too much $ there. I was thinking about getting a new Y-pipe, because after taking a look under my truck I see why people get new ones lol. Anyone see gains from those?
