im looking to get the dynomax super turbo but im running into this not being avaliable for our cars. how and were does anyone order it from?
Yup, universal. Just choose the appropriate inlet/outlet diameter. Got mine from Jegs, think it was a few bucks cheaper than Summit
Love my dynomax super turbo. Got the biggest one I could. Its like a truck muffler
its HUGE!
Ok yes I found the one I want and these arnt all loud or are they? I'm trying to get rid of the one I got, mine to loud it's a 3a racing that I got from autozone...
They are loud...
if you want something that will flow good with your super charger (in fact it is dyno proven to flow as good as any aftermarket noise maker), get a muffler off an LSJ (Supercharged Cobalt SS). You can usually find one on the Cobalt forums for like $50. Its one of the best mufflers to run on a J-body, all the power, none of the rice burner noise.
My motor is louder than my exhuast, and i make over 200 WHP without any form of forced induction.
I wish u wouls quit spouting how a lsj muffler is so much better. its not it dosent flow as well as a magnaflow or even a 40series flowmaster. yes i work for gm and i can tell you the only thing it has going for it self is its made out of ss and its quiet
see ya!
The only reason better flowing mufflers dont make more power is the tune. Thats the bottom line if u do a full exhaust system and or a intake to get the most out of it you need a tune. Pick a muffler based on how you want it to sound.
see ya!

So do you have flow charts? Not bashing just wanting to know, because I have seen the LSJ muffler paraded around and I would very much like to see charted proof one way or the other.

thats just the thing there is no flow charts for oe mufflers. i work for gm and if they wanted a good flowing muffler on a balt the would have used a duel mode system. yes the lsj muffler should be quiet but then again so is the dynomax VT over4.0L. if u want a quiet good flowing muffler the hemi super turbo or the heavy-duty super turbo. patriot has the varaflow tunable muffler also.
see ya!
In 2006 I had two Dynomax Super Turbo mufflers on my car... the truck length one and the standard one. Both 2.5in. All it was was pure bass drone in the cabin. It was quieter outside than inside. After 4days I could not take it any more. I temporally installed my old stock muffler. A month later I went with 2 Walker's Quietflow (large/small), the best move I did. Last December I went with a Camaro style SS Quietflow to save weight and better material... it was an even better move. Zero drone in the cabin and all you hear is the mechanical sound from the engine. On idle it sounds like a LSx v8 with GM's factory mufflers and upon accelerations has a flat-4 tone to it.

So you work for GM and claim the LSJ muffler is junk... without any other proof than you work for GM..
My tuner has a boosted HHR. He dynoed his car with about 20 different mufflers (using HPT for his tuning software). The LSJ muffler made the same power as the magnaflow without all the noise.
So unless you feel you know more than a Dyno... you need to hush... I am a certified Master Mechanic for Hyundai. I have no clue how their mufflers work over their others. They don't train us for that (since OEMs want people to keep OEM parts on their cars), and I am certain that GM doesn't train their employees on the flow measurements of their mufflers installed on their sport compact cars.
Edit: Just for some clarifications... I agree that Dynos do not expressly tell flow, however, if a car makes the same power between two mufflers, the flow is comparable. The point here is to make power anyway, some people like to draw attention to themselves and therefore they like noise, however the main point should always be how much power/torque the car makes. -- My tuner is highly known among the Delta guys and has tuned 90% of the local deltas around here. He's in his 60s, and has been involved with cars since the 1960s. Additionally, one of the most well known tuners here on JBO (Ryan Egleston) knows of my tuner and knows my tuner knows what he is doing.
Further, after thinking about it, the point of a boosted engine is to get air in to it quickly and then get the air out of it just as quickly. This is where velocity comes in to play. If you just change your muffler and nothing else, all you are affecting is the end of the exhaust flow. If you keep the section of the exhaust from the header to the base of the muffler constricted, it doesn't matter if you open up the end of the exhaust, since your exhaust gasses will be bottle necked already before it gets to the muffler. On the other hand, if you run too big of pipes from the header back, you cut down on velocity, and the air doesn't get accelerated and therefore doesn't reach the muffler as quickly (holding your finger over the end of a water hose is an example of this). Tuning has very little effect over power made by just changing the muffler and nothing else, since setting spark timing and fuel has little to no control over exhaust gas velocity.

So you have no facts other than word of mouth! And yes the lsj muffler is junk it was a muffler that gm put on their chitbox econo car. On a boosted app lets say a turbo the best exhaust is no exhaust then you have burrs or borla. I will say this when you show me proof the lsj flows better than a aftermarket turbo muffler i will say i was wrong but untill then i want to see proof. There is a video on youtube of a balt ss sc on the dyno that they switched from te stock muffler to a 40series flowmaster and picked up 12+hp no other changes. Hell it might have been more than that its been years since i seen the video
see ya!
There is my proof. Thats alot of power for just a muffler
see ya!
Oh sorry it was a super 44 anyway i proved my point i think
see ya!

im so sorry man but i have to do it... this is a blanket statement and is NOT a FACT for all our exhausts.
i did the lsj muffler per jbo's awesome instruction.. and ya know what? it sounds like complete CRAP. 100% CRAP, in fact. it has this frickin raspy ass high pitched ANNOYING AS HELL sound after about 3000 rpm. id MUCH rather have a fart can, at least it sounded somewhat deep LOL
now, let it be known.. i have no cat, i have no resonator. but thats besides the point. you cannot make this statement any longer. you must say
SOUNDS QUIET WITH OTHER SOUND INHIBITING ITEMS SUCH AS CAT AND RESONATOR.
now, as for flow, yes... i agree. its there. obviously if it lets this much sound go by on my car. im supercharged and it only got louder after i supercharged it.

I choose the technology built for land speed records... not the technology built to save on emissions and gas mileage.
Next time i see my tuner, i'll see if we can do the dyno again taking video this time, and we'll use my car this time. I'll see if i can get my hands on a few different mufflers and get them welded up to match my muffler flange.
Brad: Very odd... I have a gutted cat, and no resonator as well, and it wasn't until my cut out failed (and it now rattles) that i had any noise louder than the stock Z24 muffler. I plan to take new videos of my exhaust after i eliminate the cutout and replace the gutted cat with flex pipe (to save the ron header).
Yes a back to back dyno video would be awsom. hell i use my cav to drive to work 100 miles a day and yes it was too loud so now it has a dynomax bullet 20+" into a spintech prostreet into a flowmaster super40 out toa resonated tip. it flows good enough for my 34mpg avg cav. sounds nice and deep no rasp just a very pleasing tone and it will still chit and get when needed. yes it took 3mufflers but i can hear the intake over the exhaust. with that said if you want quiet use more mufflers the system will only flow as much as the worst floing component in the system they dont all add up
see ya!

well wtf? mine is loud as sin and it sucks.

I feel like it needs to be pointed out with this whole argument that no 2 dyno runs will be the same. Doing a single dyno run after installing a muffler proves nothing you must do multiple runs before and after then get an average of all runs to accurately compare.
Not that it matters get a muffler that you like the sound of if you want the sound of a fart can that's great if you want to be quiet that's great too.. Me personally I like it to be quiet with a subtle rumble tone that doesn't get loud till i really get on it and that's pretty much what I got with my flowmaster.
but you dont know how the testing was done. all i know is i made 154whp / 175wtq with my fart can and it honestly felt like it gained a little mid range torque back and didnt lose any top end when i went to the LSJ muffler. just butt dyno there though.

I went with this super turbo
http://www.summitracing.com/parts/WLK-17748/ it's the longer of the two at 20" case length. Is it loud...at full throttle yes...at normal driving not really. I can hear the intake over the exhaust and the drone on the highway is pretty much not there with all the noise jbodys make. I had the shorter version (I think part 17733) and it was way too loud and the drone was ridiculous. This is with pacesetter header, magnaflow cat, and i believe 28" resonator
i just want to stop the mis-truth about a oe muffler back in the late 80's i remember they said the same thing about the vw GTI muffler i felt like i was having flash backs lol.
see ya!
well novaracer, cobalt ss's are supposed to make 205hp on an engine dyno. so... factoring in the restrictive exhaust, you would think they'd be down somewhere around 175whp but that just isnt the case. im pretty sure they actually dyno around 210whp iirc. so that tells me the muffler flows good to over 200whp. n/a cars and blown cars this muffler should be pretty good.
