ALright guys that have been waiting on the muffler of choise for my side exhaust kit! MMagnaflow......nope,,, MMopar...... nope,,, .......FlowMMaster.....nope...... Well those of you I told were close you really were it started with an M! It's MAC! I've used them for customers in the past on Mustangs,Vettes, Camaros,TAs and GTOs and now for the Viper 10. It really does sound like sex. It does have the 1500-1800 rpm drone that every system has but before and after that it is Deep, Mean and very V-8 sounding. During the drone it sounds nothing short of a Cummins Diesel with a huge exhaust kit. Some of you whom are doing your own exhausts should love it and I can only imagine the mufflers on a Six Speed RC! They should freakin rock. I lost the decel popping just form the muffler and tailpipes. I hated that sound although many of you love it. It has NO raspy, tinny sound whatsoever.
