My 98 reg cab long bed K3500 chevy truck with the 454 needs a new muffler. It still has the original muffler and exhaust system on it. I plan on reusing the tail pipe if possible since it is still in good shape.
I want something that sounds good with a deep tone but not something too loud because I sometimes tow with this vehicle and don't want something that is going to give me a headache.
Flowmaster actually has a cat-back system for this truck using a 50 series muffler but I don't know what it would sound like.
What sounds good on a 454 powered truck? Thanks.

What replacement muffler should I put on my truck?

As I just mentioned in another thread, I love the Dynomax Super Turbo muffler. It's free-flowing muffler (no chambers) but contains sound absorbing material so it's not as loud as most "performance mufflers". When looking at mufflers myself, I was looking for good flow w/o a lot of sound. And that's exactly what the Super Turbo muffler is all about.

Thanks for the replies everyone. I will look at your suggestions. I don't want to go back with a stock muffler since I do want some sound.
I may not be able to use the TP but if not, it is not that big of a deal. Thanks again.

Dynomax Super Turbo +1
Magnaflow nice sound no drone may cost more but IMO it is the best-perfect for your big block.

ditched the third cat, upgraded to 2.5" piping, ditched the stock muffler and added a DynoMax Superturbo and it was too much for the wife. Gonna put the pro-flo in front of the superturbo. We'll see what happens...
Well, I ordered a Flowmaster Cat-back from Amazon that was actually the correct application for my truck setup(Reg cab/long bed) which the one I referenced to in my original post was not.
I decided to go with the Flowmaster system because I was unsure from my research whether to go with a free flowing muffler which most of them have no back pressure or go with a chambered muffler which does retain some back pressure. Most of the info I found suggested that the engine needs some back pressure to not lose low end power. I want to keep most of the torque and power down low on this truck.
Even though this system is not stainless, I bought the entire cat-back for only $40 more than I could have bought the Magnaflow muffler for. I guess I will see if I made the right choice.

I got the Flowmaster system installed today and I'm happy with the results. Not too loud but you know it it there. Here are some [censored] pics.
I also installed a new Delco O2 sensor in one of the inlet pipes on the new muffler since you were supposed to use your old one but I knew it would be rusted in and I was right. We later tried taking the old sensor out with no luck.
Muffler shop only charged me $60 to install the system.
I might add that I must have gotten very lucky on the price of this system because it is now $285 on amazon instead of the $160 shipped that I paid on the 19th of this month.

Waynestain less steel. and anti-seize compound on threads on the bottom, and in the pipe connection. most stainless bolts is a different alloy than the nuts, they will bind as they are put together.
I wouldn't put an expensive system on a 14 year old truck, but thats just me.
I'd also consider how many miles are on the truck.
I plan on painting the welds. It rained all day today and the truck was all wet underneath and is why I didn't get a chance to do it yet.
The truck only has 104,200 miles on it and spending $160 + $60 for the install is not very expensive in my opinion. The muffler needed to be replaced and all of the mufflers I could find for this truck were $120 or more so I considered $160 for the entire cat-back a deal.
