Hey guys how loud are the 40 series flowmaster on your rigs, right now I'm waiting for the 50 series from 4-wheel parts but it's still gonna take about 3 more weeks from today they say that flowmaster stopped shipping anything for another 3 weeks but I've been waiting for 2 weeks already, my local muffler shop has the 40s in stock but people tell me that the 40s are too loud way too loud, is that true??? that's why I went with the 50s cause of the 3 chambers supposely not too loud, they were $75 each and my local muffler shop is giving me the 40s for 135 each side I have dual exhaust so that will be about 270 for the whole setup, they charge me $100 to put the ones from 4-wheel parts on it so total for that setup will be 260 but I have to wait at least 3 more weeks so what should I do. keep blazin !!!
