    Dynomax Mufflers

    Has anyone used these on their V? My shop has a customer with a Maggied V who he installed magnaflow and zoomers for and the guy couldnt stand the drone on either system. So he welded in some Dynomax turbo mufflers and the guys loves them. Like $350 for the job....

    I've never heard dynomax mufflers on an LS motor. What do you guys think? Good idea, bad?

    Exhaust sound is a subjective thing. I always answer the same in these threads:

    I've heard 'em all, and I'd pony up for the Corsa. (Your taste may vary)
    Rest in Peace, J.D. (aka Dirt_Cheap_Fleetwood)

    I agree completely. I was more interested in whether or not any of the V owners here had done this or if anyone has even heard a dynomax muffler. I have heard just about everything but never a dynomax muffler. I also have not heard anything of their build quality.

    Not sure this helps, but I had a Dynomax on my '92 eagle talon (pretty heavily modded) Turbo - it was a good quality piece that was loud and kinda throaty (as much as a 4 cylinder can be); of course that car did also have a racing header, no cats and custom 3" pipe . . .

    After installing some Kooks headers, my Magnaflows don't drone anymore. Sounds perfect, IMHO.

    ...and I have no experience w/ Dynomax.

    yeah that helps... I was seeing if I was going to get any responses like "you are going to put what on your car?" or "more like Dynocrap" Guess Ill have to be the guinipig and post sound clips..

    Re: Dynomax Mufflers

    Dynomax has a national tour going on. The tour involves a horsepower contest where the winner gets cash and a chance to go to Las Vegas. (too bad I didn't have dynomax mufflers when I dyno'd at the contest)

    Any way, the have a demo engine setup to easily swap their different muffler lines on to the exhaust. I listened to all of them an the "super turbo" sounded best to me.

    I am very happy with the sound of by system by Stainless Works, but if you want dynomax, the super turbo mufflers did sound very nice.

    Re: Dynomax Mufflers

    I had Dynomax on 315 cube small block in a Chevy LUV a few years back. Kind of loud, like an older "muscle car" sound. The seam on one of them started to leak after a while, then they sounded like garbage. They are an "S" curved perforated pipe that goes through a stainless packing, nothing special. My opinion would be to stay away from them, but as was stated earlier, sound is subjective.

    I love my Magnaflow on my V!

    Re: Dynomax Mufflers

    Hey thanks for the feedback guys but you were too late! I decided to pass on the turbo mufflers bc my shop had a pair of used Zoomer mufflers another CTSV customer decided he didnt want. Sold the pair to me for $100 and another $90 to weld in so this way I save some cash. Not a bad deal if you ask me!

    My cat back will remain stock with the exception of the zoomers. So stock resonators should keep a quieter than regular zoomers which is all good. I get the car back this afternoon. I can't wait to hear the sound paired with my Kooks long tubes..... cross my fingers that there is no drone and they are not too loud.

    Ill post results and maybe a soundclip if I can figure out how to mic it.... who know maybe I wont like them and Ill have him put the Dynomax turbo mufflers in afterall...

    Re: Dynomax Mufflers

    Ok well the Zoomers are all welded in. I really like the sound at idle. Has a deep rumble to it. Much louder than stock at idle. At WOT and with general engine speed its not much louder than stock, to my surprise. It definately sounds different but I expected it to be louder. I do have the stock resonators in so Im sure that makes a big difference.

    Anyways for $190 installed I am really really happy. Absolutely no drone, good rumble, and not too loud. Here is a picture of the tips.... I honestly wanted them raised closer to the bumper but the guy said it would melt the plastic. How do Borla guys get away with this? Those tips are right up against the bumper and look the best, IMO. I still dont know how to do a sound clip so a pic is all you get sorry.

    Have your shop fab an x pipe and put it in place of your resonators.

    That will wake it up.

    I've never heard of anyone say that Zoomers drones. I know it doesn't on my car, even lugging the crap out of the motor, and I have the "oldest" Zoomers system around. Was he referring to B&B perhaps?

    Evidently the guy who had them on his V complained that they droned. I dont know. I dont hear anything so...

    Do you all think the tips hang too low? Im considering taking it back and asking him to adjust the tips so that they are more tucked? Yea or nay?

    Also correct me if Im wrong but if I put an x pipe in place of the stock resignators the noise will be excessive will no increase in performance. My cats are already hi flow from Kooks so I imagine that helps..

    No, I was going to put some Dynomax mufflers on the car which has Kooks LTs and a stock cat back.... mostly to make it sound better and give it better tips... wasnt really interested in spending close to a grand on a cat back for no improvement in performance.

    But then my guy at the shop mentioned his other V customer who he installed a Zoomers cat back for. The guy didnt like the sound and had the shop cut the mufflers off and replace with Dynomax mufflers. So he had the mufflers just laying around and offerred them to me cheap and welded them in.

    So Im all stock in the middle. I suppose its a little unusual.
