muffler for 96 454 vortec, too loud??

i just bought a 96 chevy with the vortec 454. i want to put a muffler on it to get a little more sound and peformance out of it, but i am nervous it will be too loud on the highway.... i am just replacing the stock muffler and leaving the stock tailpipe... i was looking at the flowmster big block muffler, or just a plain flowmaster, are these loud on the highway? i was also looking at maybe a dynomax or gibson.... basically i want it to sound nice but not have a loud drone at 75.... any tips would be great!

i have the same set up as you, and i currently have, i believe a flowmaster 70 series. I don't mind it at 75, you have to talk a little louder then normal, but i don't talk much when driving anyway. i should also mention i got 4.10's and 31's. but loudness can only be determined by you. And yes interior noise is louder in the suvs then in the trucks.

The 70's aren't that loud. I would do the 2 in to 1 with a 3'' pipe out the tail to keep it alittle less noisy.

I don't know if they make a dual inlet or not, but I run the Flowmaster Hushpower II on my XJ and love it.

What Spintech model do you run and how is it as far as noise.
We run a race model Spintech on our race cars but I don't know anyone who runs one on the street. If you don't want any drone then the Walker (superflow?--forget what model but its below the Ultraflow) is nice. If you don't mind just a bit of noise at cruise the Edelbrock stainless with the two split tubes is nice. Alot more power than the Flowmaster and a bunch quieter.

I run one of the Flowmaster big block mufflers (70 series? the case is 22" long). Single 3" in/out, behind a mild TBI 350, no cat. Nice sound, not loud.

Yeah, the bigblock series mufflers should sound good and not be too loud. I have a 40 series flowmaster, 3" in/out, no cat, turned out in front of the rear wheel on my F-250 (460), and at 75mph there is somewhat of a drone. Hook up a 10,000lb+ trailer and she's really talkin' to ya at 75mph. I love the sound, and I'm actually going to step up to a super 40-series, hope its not too loud. But, for you, any 50-70 series would work fine.

I talked my buddy into putting a just a muffler on his 5.4L superduty instead of replaceing the whole system. He went to a local shop and they put on a Magnaflow. It has a nice mellow rumble @ idle, and is nice on the road. No drone and you can only really hear it if the windows are down. His truck has a stock 3" pipe behind the convertor, so it is single 3" in and out with about a 16" case.

Me and a couple of buddies own similar 7.4 C3500s, they both have flowmasters with a 3" tail, One has the 70 series, one has a 3.5" 2 chamber necked in and out to fit the 3" pipe. I have the gibson with a 3" on mine. The flowmasters sound much better than the gibson hands down, the 70 series sounds nice with out any drone at hwy speeds, the 2 chamber race muffler sounds nice running around town, but after driving it on the hwy I can say it sucks... My gibson is loud and raspy, but doesn't have the cool tone the flowmasters do, and I think it is louder inside at speed.
