New LS1 Owners - Newbie Tech - What's the best muffler to buy

Whats the best and cheapest muffler for my 2001 z28

Well do you want best or cheap? Those two dont really go together. What kind of setup are you running as far as headers and alll or is your exhaust stock and you just want to slap a muffler on it? Either way go with a mgnaflow race series. Good sound and great flow

Dynomax is cheap and good

Put a manual cut out

Eh id do an electric cutout if i did a cutout

loudmouth

Well best and cheapest do not go together/ figuere out which you want the best or the cheapest

Best is kooks complete dual exhaust but you will spend 1800. Need kooks long tube/ magnaflow is also one of the best/if you want cheap flowmaster is ok slp stuff is ok

I just wanna slap a muffler on it now and later put headers on it. What would sound the best with stock exhaust

Dynomax

Does dynomax have a good sound?

Go magnaflow, ive heard dynamax and personally dont like it. Go ahead and do a good magnaflow race series now because if you cheap out now youre gonna end up having to do another muffler when you do your exhaust and cost yourself more money in the long run. The magnaflow will flow good with stock exhaust and flow even better when you do a full exhaust and will sound good too. Like i said good and cheap dont play nice together and generally cheap ends up costing you more money down the road

+1 for Dynomax

Does dynomax have a good sound?

Yes, the Ultra Flo is similar to Magnaflow in construction and sound. I have put dynomax on my 78 408 Camaro and my Ex-GF's 96 Chevy 1500 they sounded great on both.


On a 4th Gen:
17227 for 3" Inlet and 2.5" Duals or
17536 for 3" Inlet and 3" Duals.

The Magnaflow 12267 is also 3" Inlet and 2.5" Duals and 5$ Cheaper at Jegs FYI

Another thing to point out is that the Magnaflow is slightly smaller in size compared to the Dynomax, but either one will sound great. It's a V8, you can't go wrong.

Either a Magnaflow#12267($105 summit), or Dynomax Ultra Flo Welded #17227($108 summit), both are stainless steel.


#17227 is $86.56 shipped
#12267 is $100.28 shipped

Both on Amazon.

i think they come factory with a magnaflow.
so why change it?
theres nothing wrong with it

Magnaflow is aftermarket. You can get a Flowmaster 80 series muffler for around $100.

i hated my magnaflow... it was weak and puny sounding and resembled a pissed off mosquito a WOT. Im not much of a fan of the moroso spiral flow either.. i had one laying around so i used it since its all i had. look into the classic chambered mufflers and the sweet thunder mufflers.. they sound deep at idle and scream at WOT.

SO mufflers to avoid

Magnaflow
Choke-Master (flowmaster)
moroso spiral flow

You can get a Thrush welded muffler for like $40. They are copies of a Flowmaster 40 series.

I don't know, mine doesn't sound weak and puny at all. Maybe if you try putting one it on a engine that's not weak and puny you won't have that problem. So everybody should avoid putting the Magnaflow on a weak and puny engine, like TyCZ28 did. :D :jest:

ok think what you want... i just know a magnaflow isnt as loud on any application as id like... and they sound like A$$ in the upper RPM band... ive had one on 4 different vehicles and only 1 of them didnt sound like a POS. my 01 silverao with longtubes and true duals with magnaflow bullet mufflers sounded crappy at anything above idle, my 97 lt1 with stainless longtubes and ORY sounded like crap, and my 79 camaro with a SBC and a healthy cam also sounds like A$$ above idle but we wanted a quiet cruiser. however my integra that i used as a put around car had one and actually sounded decent... for a rice burner.. im also willing to bet ur car sounds like A$$ too... theres a ton of better sounding mufflers for an LSx.... Borla, Corsa, Kooks, SLP, Hooker, GMMG is by far one of the nastiest sounding and sweet thunder and classic chamber are mufflers designed just like the GMMG ones.

:lol: Dude, I'm just messing with you. :lol:

I'll have to agree that my exhaust might sound like ASS to you, but to me it sounds good; like Fine ASS!

Exhaust sound is just another thing that you have to make your own decision on what sound good; everybody's has their own opinion on what sounds good. :thumb:

IMO, you'll really just have to get out and hear different mufflers to find out what you like.

Now THAT i will agree with :nod:

Magnaflow has a tendency to sound like stock until you get into some RPM and then you can tell its there, but it's not necessarily in your face exhaust.

Flowmasters, are at autozone and on 1/2 the mustangs you see around.

The loudmouth tends to have a strange sound to it, and can be a lil poppy depending on what vehicle its going on.

Me personally.....I went to the dynomax and it is wicked. Has been my fav so far.

Here is a vid of it on a stock car, then with cam and headers. Of course its alot better in person vs and iphone.

The sound to me is pure muscle. people with 6 speeds wont be able to hear when to shift when racing you. guaranteed. but not just loud....great tone. just my 0.02

Does dynomax have a good sound?

Don't know, but they made 2 shitty ORY sets, I ended up getting a MAC system. As far as a catback, you wanted cheapest that fits in stock location... a slowmaster is $95... p# in Jegs is 389-42583 that's a 2.5 inch inlet to fit stock I-pipe or chamber pipe if you will...

Words of advice, if you just bought your car and it's the first car you're modding... order a jegs and summit parts catalog

What dynomax is that I8UR4RD? I like the sound of it

sounds really good i like it

Not exactly cheapest but I'm a fan of how the Borla xr-1's. They put out a nice low sound

Dynomax Ultraflos are amazing I currently run a bullet muffler after my y pipe to dual rears and I love the sound. Its a bit aggressive for most people but not over the top like loudmouths. The Ultraflo would be a nice compromise between flow, sounds, and expense IMO.
