Okay well you guys don't know me all that well but I have been lurking around here for awhile. I have a problem with the way I feel about my exhaust setups after I have had them a while (a while being a couple of months). In the past year I have had 5 different sets of mufflers. The mufflers of choice include warlocks, flowmaster 40s, forza flows, dynomax bullets, and now one chamber flows. Well to say the least the one chambers are loud but I was hopeing for the sound of the flowmaster 40s but louder. But these mufflers sound nothing like the 40's they sound more like the dynomax bullets. I guess they will do for now. I just wanted to share my experience with you guys.
