stlunatics2oo3 Posted September 26, 2002 Report Share Posted September 26, 2002 i am gonn abe getting a new muffler and i was wondering what type of muffler would be good for my vehicle performance and sound Quote Link to comment Share on other sites More sharing options...
eclipse5302 Posted September 26, 2002 Report Share Posted September 26, 2002 I use a single Flowmaster 40 series 3 inch. It is quite loud, but it flows enough to keep the turbo happy, and it was the only 3 inch muffler avail to me locally when we decided to weld up the exahust.

93 Cutlass Posted September 26, 2002 Report Share Posted September 26, 2002 I have two Dynomax Ultra-Flow stainless mufflers ("dual" exhaust), two Edelbrock flat oval chrome tips (kinda like a trumpet effect like on the '68 442), and a Dynamax Super Converter high-flow cat. My 'ol 3.1 sounds damn near like an eight! Nice low grumble, but at WOT, the sound tends to die off. But at least my K&N cone filter takes over then. The exhaust I know added some ponies (especially seat-of-the-pants) and awesome sound. If the K&N did not add any power, it makes up for it in sound!

MaD Posted September 26, 2002 Report Share Posted September 26, 2002 Yeah, I have the Dynomax Super Turbo muffler, it flows enough so I gain performance without losing low-end torque, but um, I kick myself for not getting the Ultraflo Stainless. My muffler is nice, it was only $40, and it has a nice exhaust note, but it's a bit quiet and there still seems to be some backpressure above 2000 rpms, it just gets all quiet and powerless.... I'm hoping that this restriction in the air flow is my 11-year old non-high-flow cat. So, I'll keep this muffler until I get a high-flow cat installed, maybe that'll fix what ails me If not Oh well....there's always next time I guess. and next time, I'll get that Ultraflo SS, fah shizzle werd right, shun -MaD- Quote Link to comment Share on other sites More sharing options...
LukeZ34 Posted September 26, 2002 Report Share Posted September 26, 2002 I'm still running the stock setup, but eventually I hope to upgrade to some Magnaflows here someday. Quote Link to comment Share on other sites More sharing options...
RedZMonte Posted September 26, 2002 Report Share Posted September 26, 2002 My recomendations are: Borla Magnaflow Dynoamax Ultra Flow All are good high flow mufflers. i would also recomend upgrading your resonator if you reuse your stock piping or add one if you redo the piping. If you replace your cat i would recomend Carsound 94006 (2.5" in/out). it is a 50 state 100% street legal High flow cat. RedZ Quote Link to comment Share on other sites More sharing options...
MaD Posted September 26, 2002 Report Share Posted September 26, 2002 We have resonators? Where are they located? I'd love to get rid of mine, if I have one... 91 CS sedan 3.1 -MaD- Quote Link to comment Share on other sites More sharing options...
crazychuck29 Posted September 26, 2002 Report Share Posted September 26, 2002 hey shane you are doing a catback right?! what mufflers are you gonna use Quote Link to comment Share on other sites More sharing options...
crazychuck29 Posted September 26, 2002 Report Share Posted September 26, 2002 my 3.1 has never had a resonater and i' think some of the older gp 3.1's didn't either but i could be wrong i don't know about the olds.... Quote Link to comment Share on other sites More sharing options...
RedZMonte Posted September 26, 2002 Report Share Posted September 26, 2002 We have resonators? Where are they located? I'd love to get rid of mine, if I have one... 91 CS sedan 3.1 -MaD- Generally they are by the rear wheel. on the Z cars its right before they Y. i assume they put a small one in stock. here is my borla kit being installed. the resonator is about where his hand is on the piping (same with my stock exhaust on the monte and the lumina) I also pollished the mufflers myself: RedZ Quote Link to comment Share on other sites More sharing options...
RedZMonte Posted September 26, 2002 Report Share Posted September 26, 2002 hey shane you are doing a catback right?! what mufflers are you gonna use I am making mandrel bent midpipes. when they are ready you will need to get your own choise of mufflers. but my cars have 1. Borla Catback and 2. custom 2.5 catback with magnaflow mufflers. RedZ Quote Link to comment Share on other sites More sharing options...
Guest Posted September 26, 2002 Report Share Posted September 26, 2002 :?: I've heard that it's hard to get a good rich throaty sound from the 3.4. Can anyone reccomend a setup that would sound good but not too loud? I still want to enjoy my jam system but right now the car is quiet as a mouse w/ the stock settup.

Brian P Posted September 27, 2002 Report Share Posted September 27, 2002 NOPE NO stinking resonators on the 3.1 cars until like 1999 Quote Link to comment Share on other sites More sharing options...
LuminaASG Posted September 28, 2002 Report Share Posted September 28, 2002 I am having to think that my input on mufflers for a w-body isn't very helpful for the reason of having a cadillac motor (go figure) but still I've got dual magnaflows and it sounds AWESOME!!!!.. I get some crackling when getting into it but a pretty deep rumble when idling down.. If you check out the design on the Magnaflows it's jus a slight bent pipe with holes through it. no baffles or nothing Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted September 28, 2002 Report Share Posted September 28, 2002 NOPE NO stinking resonators on the 3.1 cars until like 1999 The '94 Cutlass I bought has a resonator. It has the 3100. Quote Link to comment Share on other sites More sharing options...
Brian P Posted September 28, 2002 Report Share Posted September 28, 2002 OK that's right, I forgot the 3x00...didnt the resonators get HUGE in like 1999? Quote Link to comment Share on other sites More sharing options...
Lee Posted September 28, 2002 Report Share Posted September 28, 2002 If you look at my "bare bones" web site, created just to get some pics up...You'll see my dual dynomaxs'. I ended up puting sheet metal shaped into pipes into the resonator tips until I figure out my trouble. (it sends the exhaust straight through avoiding the resonator grid.) I'm looking at replacing the cat, which is gone, or puting another muffler in its place. The rasp hits at around 2000 rpm and is an ugly a$$ sound (like blowing on a popped balloon end). It idles like a V8 4x4 and sounds tough until the rasp hits. It clears out some at higher rpms but It just won't do to leave it this way. My highway torque is most awesome though so I hate to add more backpressure. The left side gets most of the exhaust, especialy when cold and it is noticably raspier. I plugged that side once to listen to the sound from one pipe. It was better but there. I wondered if the muffler was bad. Quote Link to comment Share on other sites More sharing options...
NORBI Posted September 28, 2002 Report Share Posted September 28, 2002 I would go for BORLA, i was thinking about putting a Flowmaster muffler on my Oldsmobile with 2.8 but never done it, but i put a cat back BORLS setup on my 02 Mustang GT and i got to say that it sounds better than Flowmasters. And 2.8 engine with borla will sound just like a v8 Quote Link to comment Share on other sites More sharing options...
