I'm trying to find the right median between loud around town and quite on highway trips. My exhaust is very loud right now because I'm running longtube headers, no cat, and the flowmaster super 44. I know if I run a 50 series muffler, it will still be louder than usual because of the 3" non restricted exhaust, but do you think it will eliminate highway drone? I love the drone and rumble around town, but when I need to do long trips with the truck, it makes me want to vomit after the first hour of it humming going 75 down the highway!

 

Honestly I don't think my 40 series is that bad but I have stock manifolds and a Magnaflow cat. Anyway what I had before was a lot better. I thought it was a 50 series but Summit list the dimensions for the different mufflers and this one was a different size than a 50 and measured the same size as the 40 series ones. Maybe it was just setup differently or a different 40 series I'm not sure. Anyway it was pretty quiet in the cab. Not loud at all but pretty loud outside the truck. People were amazed after getting in and it not being loud at all. This 40 series is a bit louder inside and maybe some but not a ton louder outside. I like it but sometimes it's boderline loud where as the other was sometimes border line not loud enough. I wish I knew which one it was to tell you to try but I think it was about perfect. The 40 I have now is good but not quite as perfect sometimes.

 

It just sucks because I do love it loud. I love stealing the show across town. It's incredibly loud and unique sounding, and has many different tones to it depending on how much throttle I'm putting into it. Sometimes it's deep and bassy, othertimes loud and gurgly, I love it. But when I'm taking a 3 hour road trip with the quad in the bed, it just takes over the entire cab the whole way up. At 75mph, the truck is just overbearing, and passengers hate it. And so do I. I want something that can still steel the show around the city, but can basically be a background thought on the highway. I realize it will always drone, but mine is unbearable on the highway.

 

not to change the subject, but you said you have longtubes, im assuming that you have a 4x4, where did you get them from?

 

I got them from ebay last winter. This guy has a very good price. I think it's around $530 for the ceramic coated longtubes with the matching y-pipe. Here is the link.

Mine honestly isn't that bad at highway speeds to me anyway. I don't really notice it although I usually have the stereo on. I might be able to hear it if I didn't have it on but it still isn't horrible. I think your gutted cat and maybe headers are part of yours being so loud.

 

i'd love to get a set of longtubes, but I dont know if I'd be better off just getting a set of shorties or going with the longtubes

How big a pain were they to install?

 

The drone isn't from the muffler. It's from the gutted catalytic converter. So just put real one on and the drone will go away.

 

That's kind of what I'm thinking. Mine doesn't seem to be all that loud at highways speeds. It seems to be okay in OD. Sure it might drone a little but not so you can't stand it like you describe. I think my exhaust got slightly louder with my Magnaflow Cat over the stock one but it still isn't horrible. I'd try putting a cat back on and see how you like it. It may not fix it but worth a shot.

 

You would think it was from the gutted cat, but I was having this problem since the first day I had the system put on. Originally it was a 3" in/out magnaflow cat, 3"in/2.5" dual out super 44 muffler, and it was extremely loud. Didn't crack as much as it does now, but was still very very loud. So Cereal, your saying the muffler doesn't cause drone? I thought the mufflers dictated the amount of interior resonance there was going to be. I assumed going with a less intense muffler might kind of equal out the headers and gutted cat?
