I just got an 06 gmc sierra, I'm planning on going in next week to get a new muffler for a throatier sound, it's a toss up between dynomax and Flowmaster...What do you run? If you have experience with these two options which do you like more? Any opinions would be helpful, thanks in advance!

Flowmaster all the way! Get 50 series though or they will probably be too loud for you. The dynomax is junk imo, you could park your truck on top of the flowmaster without hurting it but would crush the dynomax like a pop can, long term durability and the flowmaster wins every time. Flowpro is junk too, a little tougher than dynomax but still garbage. My truck had one on it when I got it and it's internals rusted out completely, it developed a loud droning sound and when I picked it up to shake after it got cut off it sounded like it had about 10 lbs of rust in it.

I've never considered it possible there could be a toss-up between Dynomax and Flomaster.

I haven't heard too many negatives about dynomax until now haha, sounds like flowmaster it is. I was thinking 40 series but sounds like 50's is the way to go..I dont mind loudness though, I did just come from a 5.9 cummins with a loud exhaust and loved it! But regardless thanks for the opinions!

I get lots of comments on my Flowmasters (all positive) very throaty. Also makes many young guys pull up along side and want to see if it go.

I have dual 40's on my hotrod, it sounds like it belongs on a track, I have a 50 on my tacoma and it can be heard for a few blocks.

I had 3" 40's on a high-compression 427 bbc. Loved it. Neighbors didn't. ..

I too have dual 40's on my 72 blazer w/400ci small-block. They are pretty loud. I'm thinking about swapping out for 50 series.

Put an AFE air filter in the stock housing and call it good, most of the aftermarket stuff just makes more noise and makes it easier for water to get in.

Ok that makes sense and probably cheaper! Thanks FC!

Are you just swapping out the stock muffler for a louder one? If so I'd go with a 40 if you want throaty. I have a 40 on my f150 and it's not really that loud. At idle you can barely tell its not the stock muffler. Sounds good when you hit 1700+ Rpms though. With all that said I much prefer the sound quality of magnaflows over flowmasters.

ICEMAN · « **Reply #12 on:** February 05, 2014, 08:12:41 PM »

You young whippersnappers crack me up....

Later in life, you will look back at decisions like this and just shake your head.....what was I doing...?

Put a nice quiet stock muffler on it like designed and make your neighbors happy...

I want to say I have a 70 series Flowmaster on my '02 Silverado. It's been there 5-6 years and I can't remember for sure what it is. It's not too loud. I had a Corsa cat back on it from GM Performance parts and it was soooo loud and there was a lot of drone.

I think their product does last longer than most others from what Ive read on gm forums..guess its just a matter of which to go with..i will probably start with a 40's and then go from there since the rest of the exhaust will be stock I forsure want a good throaty sound

If all you're concerned with is the sound, look on YouTube for some video. You'll be able to hear what they sound like.

BULLBLASTER · « **Reply #18 on:** February 05, 2014, 09:28:17 PM »

I put a 16 inch flo pro on my Silverado when brand new and I now have 88k on it and it is still going strong... sounds same now as day one. Sounds like a truck... not overly loud or annoying but a bit throaty.

I think a 40 will sound decent on that truck. Magnaflows from what ive seen are generally a little bit more mellow, but have a much more natural sound in the higher rpms whereas the flowmasters seem to just become a loud drone. My next one will be a 14" magnaflow.

coachcw · « **Reply #20 on:** February 06, 2014, 06:47:37 AM »

magnaflows sound good to much droan from 40-50 series fm. I put a stock duramax muffler on my 09 6.0 chev that was a take off , it woke it up and doesn't drive you outta the cab

buglebuster · « **Reply #21 on:** February 06, 2014, 07:00:38 AM »

When I had diesels it was 4in straight pipe and that was the only way to go. A year ago I got a f150 and decided to keep it quiet and stock, best decision of my life

my buddy drew an eastside archery bull tag last year and it sure was nice to pull up to a spot on the road, bugle out the window and get a response! Never do that with a loud truck! Haha anyways ive alwayd liked the sound of the flowmaster 49.

maybe you can find a guy that pulled his duramax muffler off

Here's a dumb question about exhaust sound.
Does sub zero temps make an exhaust sound louder? Mine seems to the last couple of days?

Coach I'm not sure, I can look around and see. If not My buddy did do a flowmaster on his truck and it doesn't sound too loud. It's Probably what I will go with I cant remember what series he has though Ill have to double check. I think the duramax would be too big, I'm only running a 5.3L vs a 6.0 I'm not sure of the measurement difference though. Something to consider.

DRobnsn · « **Reply #26 on:** February 06, 2014, 11:13:14 AM »

If your looking to be a little different check out Borla's stuff. Good quality stuff without the run of the mill flowmaster sound. Don't get me wrong I love flowmasters and the way they sound. I've had Flowmasters on quite a few different vehicles but when I did the exhaust on my 69 Camaro I bought Borlas and constantly had people asking what exhaust I was using. I second checking out Youtube for sound clips to help with your decision. I also second the fact you can park a semi on a flowmaster and it won't flinch. I had a set that have been used on 4 different rigs from cars to 4x4 trucks and they have been sitting outside in the rain for over 5 years now with no rust I'll use them again someday.

coachcw · « **Reply #27 on:** February 06, 2014, 12:19:46 PM »

Borlas sound bad ass on the northstars

baker5150 · « **Reply #28 on:** February 06, 2014, 12:58:07 PM »

My hunting partner put 40 series on his suburban. Sounds great. Not too loud in the cab, but once we started pulling the travel trailer to Elk camp a couple years ago he regretted it. He had the exhaust piped out the back and man was it loud while towing. We figure the sound was bouncing off the trailer and echoing towards the truck. Especially over the pass where he gets on it for miles at a time.

We take my rig hunting now.

huntandjeep · « **Reply #29 on:** February 06, 2014, 07:05:53 PM »

Another vote for Flow master. I have put them on every rig I have owned. Always went with the 40 series on had 2 rigs that it was obnoxiously loud. One was a 78 Chevy short/wide bed with a built 502 running 2 1/2 " headers into 3" duals dumped over the axle. Couldn't have a conversation above 20 mph ( man I miss that truck) the other was a Honda crx, ya it was bad

Alchase · « **Reply #30 on:** February 07, 2014, 12:34:36 PM »

If you have someone else install a Flowmaster or Magnaflow, make sure you are not getting an aftermarket knockoff!
I had a Magnaflow on my 02 Ram that made it sound great. A buddy liked it and went to a local "Exhaust shop" to have one installed. It sounded fine. Three years later his was already rotted through. Mine was still going fine after six years.

I got dual 40's on my 2004 8.1 big block and i cant stand them. They sound good but way to loud for normal driving. Can't wait for them to wear out so I can get some 50's

dont bother with a cat-back unless you do something before the cat...

a good set of stainless headers would be more gooder...

You didn't exactly say it but if you are suggesting a kitty disappearance, that's not such a good idea since it appears the OP lives in the emission test zone.
