dynomax turbos?

[jakes2500]

I'm getting ready to have duals put on my 2000 2500 6.0..... The shop recommended me to use dynomax turbo mufflers instead of flowmasters to save money. Does anybody have any experience with these muffs? How do they sound with 6.0?

dont be afraid to spend some money on a muffler...its definitely worth it. i hear corsa and borlas sound mean on a 6.0

The Dynomax superturbo's will outperform any Flowmaster, but you might be let down by how quiet they will be. The superturbo is right in par with a Flow 50 to 70 series... stockish idle and a little more tone when throttle is applied, but definitely not on the loud side. Not sure what you are looking for as far as volume but like it was mentioned, don't skimp on the muffler. The last Dynomax superturbo I installed lasted about 4 years before it rotted from the inside out. Same will happen with any muffler made out of aluminized steel no matter what brand or style of muffler you opt to use.

If it were up to me, if I wanted to save money and wanted that chambered sound, Thrush welded in the stainless steel variety would get the job done nicely.

Depends on your location and how much they salt the roads, I've never had an aluminized muffler rust or rot out

I'm not gonna lie, super turbos are a bit on the quite side. I'm not a fan of flowmasters or glass packs as the always seem too loud and harsh. I've had mine a year and the Canadian winters hasn't caused any rust. I've heard good stuff about the dynomax ultra turbos and corsa's as well.

on start up it gives a bit of rumble, then settles down on idle. it has a nice growl when your on the gas. it doesn't piss off neighbors but it still turns heads :)

My buddies 5.0 mustang has dual super turbos with x-pipe and it sounds like heaven...

I had true dual thrush turbos dumped right behind the cab. I liked it, rumbled, classy sound, but yeah, kind of quiet. You could tell it wasn't stock for sure, but not gonna break any db meters that's for sure. But I liked it.

If you don't let the exhaust get hot enough before shutting it off, condensation builds in the muffler and rusts it out inside, so on the outside it may be fine but inside it's rotting away, which is why I always have mine run for 15 minutes before I shut it off.

Also to get an idea how quiet they are, going from stock muffler to a turbo muffler, it'll probably sound the same. I had one on my old van with the stock cat and even after I ran the muffler open, still sounded silent. I had Borla Turbo's on my 87 5.0 Mustang, had shorty BBK headers and o/r H-pipe, those were 2.5" but bolted to the H-pipe the intermediate pipes reduced to 2.25" then it went to the mufflers and ran out the side in front of the rear tires, and it was still really quiet, at least it sounded like it to me. If the muffler and pipes are a larger diameter it'll be deeper and louder, but I was surprised that with headers and no cats it was that quiet. Also, mine were u-turn mufflers for the side exit so that may have made them even more quiet, not sure. I prefer straight through like Magnaflow or Borla, or if you like the chambered sound try the Hooker Aerochamber, the Aero Turbine 3030 or Spintech Pro Street.

:LOL: Was extensive testing done to arrive at this 15 minute figure? Condensation is gonna build up in the pipes regardless since it's a by-product of an internal combustion engine

I never said they couldn't rust or rot out, I just disagree with the ''you have to buy stainless or it will rot out'' belief because that's not been the case for me.

Condensation is a by-product but i've found after 15 minutes it doesn't drip out of the tailpipe and it's hot enough that it evaporates and doesn't collect as much in the muffler, provided it's straight through so that after the engine is shut off the vapor can still escape. No I haven't done extensive research but this has been the case on everything I own as well as a method used by others and seems to work well, better than the start the car up, throw it in gear and drive it hard then shut it off, that's when your exhaust looks like swiss cheese, seen it many times before. In the auto shop in high school kids would bring in the car to have the exhaust replaced, before we did the work I would ask them to demo how they usually start up the car and drive, and every one of them would fire it up cold, put it in gear within a few seconds and drive off, no warm up time.

Say what you will, i'm just speaking from experience. Yours may be completely different then mine, and that's fine, I never said you're wrong and i'm right.
