hey guys i have a straight 3" pipes out to rear axle and then y pipe to duals....they were loud as sin for awhile there but now they have gotten a bit more quiet (like 20 decibles) and i cant figure out why. no more smoke than usual. no rough idle. no precievable loss in either power or economy (maybe just alittle ). any ideas whats going on? coming up on an oil change but i dont think thats problem . tightened the belts recently, added some synthetic to the oil fill. been using different diesel stations to fill up recently out of necessity, but man im just stumped.
