Xcelerator muffler installed

had a local WearMaster install it for me today on my 04 4x2 Prerunner, cost $185 out the door. For some reason it doesnt sound like my old one this one is a mix of traditional Flowmaster sound and kinda like a Honda fart exhaust, inside the cab its more like the Honda but anywho theres a nice difference. At idle it sounds stock, it starts to sound different once you hit about 30-35 mph. Its straight through like a mo fo. Anyone else doing it go with the X-105 (for 4cyl.) you'll have to get a reducer installed before the muffler. I'll repost if it starts to change sound after it gets broken in
