    I was the first one to get Flowmaster Super 44 in my area. I dont know who was more excited to hear the sound me or the guy who was putting the mufflers on. After they were put on a guy, waiting for an install after me, who originally wanted Flowmaster 50 series changed his mind, and asked me if he could ride with the installer to hear how much sound was in the cab. As they both got out of the truck it was nothing but smiles from all three of us.

    Needless to say the installer said that he was going to order alot more of the mufflers. Since then he said that he cant keep them in stock.

    My beast had a magnaflow and I hated it, tons of drone, it rotted in under 3 years so I had a flo-pro put on, love it! Betty throttle feel with it, no drone and way better sound, my mule however I will be going with a flowmaster Super 10!

I've decided its time for a new muffler! I've looked at flowmaster 40 series and dynomax ultra-flo welded series because I still want it to be loud! What mufflers is everyone else running and what suggestions do you have?! Thanks!

    I tell you what, I have always been a huge fan of Flowmasters. I have had them on my 71 Chevelle for almost 10 years, they still sound as good as when I first got them. To me, glass packs are only good on old Lead Sleds, but that is just my point of view. On anything else I would go with Flowmasters, they are high quality and sound amazing.

    Well since nobody will speak up for Magnaflow, I guess I will. I'm running a simple single in dual out magnaflow muffler and I really enjoy the way it sounds. I liked it more when I didn't have cats on the truck but it still sounds good. I don't get drone in the cab and cruising at 70 mph it's relatively quiet. As for the quality of the muffler, it still looks great and I've had it on for 2 1/2 years. Nothing against Flowmaster because I think they sound great, but I decided to go with something not everyone else had (as evidenced by this thread )

    For those of you like me who don't know what drone sounds like here is a good video.

    This is a 2005 Nissan Titan. You can hear the drone about 2:25. I had to turn my speakers all the way up to notice it or you can use headphones. It is annoying as hell.

    Anyone got any specific advice if you don't have a big honkin engine. I have an old 305 in my 91. I was planning on getting new duals put on. Right now I'm running factory and it's barely audible. I want something deep but not extremely loud. I read in the thread someone recommended flowmaster Super 44's and the 50 series. The guy who's going to be putting them on is recommending a 40 series. Do you think I'd be happy with that considering what I want? Thanks guys.

    Here's my Flowmaster 40 with the 4.8 liter:

    Need to get a new video of it. I personally think it sounds better now that it's been on there for awhile.
