Dansk GT3? vs. M&K GT3 muffler

[78SCRSMAN]

Hello all... I'd really like to install a GT3 style muffler like the M&K but have read many posts about it being on loud side. Enter the Dansk GT3 muffler.

So far, I haven't read anything about it. I'm guessing it's too new but would like to hear any comments from anyone who has purchased one in regards to sound. If you've tried both, that would be even better!

Interesting. Do they also make that in a 1-in, or only the 2-in?

One obvious difference will be that the M&K will be much lighter. Their use of 321 stainless is a major reason to go that direction.

[78SCRSMAN]

It appears there's only a version for early HE's/SSI's

I don't know the weight of the M&K but this one tips the scales @23lbs... also is made from steel. The weight difference wouldn't be as much of a factor as the db levels would be.

Patrick Motorsports sells this as well as Rebel Racing, although the tips are different.

My M&K 1 in 1 out is less then 12 pounds. The M&K will weigh less.
The Dansk may be made out of steel or stainless steel but it won't be made out of 321 stainless. 321 is rarely used as it is more expensive but it is a high heat aviation grade of stainless and is the correct choice for something that will last.

I love the sound of my M&K GT3 Style (When I got it it was Custom..) and I have has 1 in and 2 in. I cannot compare it being louder then the Dansk, but I think it sounds great. Since that is all opinion, and no Db levels, not sure the help. I also like the Raw look of the M&K over this Dansk. Raw finish, looks like the day I got it.

What are you putting it on...stock motor...I'd go with the Dansk as it is better tuned for stock.
Modified then the M&K as it is freer flowing and a modified motor (cammed up/more cubes) can benefit from that.
Lots of threads about free flow and mid range torque out there.

Most m+k mufflers are in the 14-16lbs range from what i understand. Except the 1 in 1 out which is 10lbs.

[RarlyL8]

Our 2/GT3 weighs 14 pounds. The single inlet version weighs 12 pounds.
The sound is aggressive. I don't know what the others sound like but if you are after stockish sound level ours will be too loud for you. Typically our dual inlet mufflers are from 92-94dB on the race track with headers on 3.0L-3.2L engines. We offer 2 types of baffles or internal caps to tailor the sound level. The look is completely different as well, so your choice really depends on many things, look, weight, materials, and sound level.

Here is an example of the basic look. This one has Rally tailpipes:

That is fairly lightweight which is a plus. The baffles you mention... are they internal to the muffler itself or mounted in the outlet pipes? What effect do the have when installed? I definitely would like a sporty sound, just not a "look at me officer" type of sound. I guess in the end, the proof is in the puddin... I'm going to need to hear one in person I suppose. Anyone in/near Spokane that has a two in/out M&K?

Just an FYI, the patient is going to be a 3.2SS with carbs and low RPM cams (for lower torque)

One other thought... I was perusing your website and ran across a paragraph that mentioned "GT3-S" style exit pipes. What does that look like? and is there a slight premium on it?

Would the exit pipes look like this?

[RarlyL8]

The GT3-S is the GT3 with 3" tailpipes.




This one has passive tailpipe baffles. The 3" tailpipes are pretty loud, the baffles bring it back to standard level.

Those baffles have to do more than just arrest sound?

[RarlyL8]

No they just tone it down a bit. The ID of the tailpipes is way more than the power level demands, which is a single 2" tailpipe. These are a custom order item as they are a bit too agressive for most.

[Reiver]

Yeah, that's a lot of total area exit.
Do most that order your fine product discuss the other aspect or just the 'sound'?

[RarlyL8]

I always ask what the application is and what they want out of the exhaust system. The 2/GT3-S is an extreme example which is best suited for highly modified engines where top end rules. You would loose some bottom end with a stock engine and this muffler. If the client has a stockish engine and wants the "look" then we talk baffling to retain bottom end. The last thing I want is someone disappointed in the sound level or performance. The quality they will never be disappointed in.
For the regular 2/GT3 with 2.5" tailpipes I recommend some type of baffling if the engine is bone stock and noise level is an issue. Sound is so subjective that it needs to be discussed when purchasing a dual out muffler. What one guy thinks is awesome another will think atrocious.

Bumping this old thread to see if anyone else has tried this exact Dansk GT3 Style muffler pictured by the OP.

[Busta Rib]

I had the Dansk GT3 muffler with SSIs on my car (1977 with 2.7). It is louder than stock, which I didn't mind too much, but it also droned between 1800-3000 RPM. Couldn't stand it and replaced it with a Dansk 2-1 Sport Muffler. Sounds more like stock but a little louder at WOT.

Interestingly, I have the Rarlyl8 GT3-S muffler pictured above. It came with the 3.6 engine I am currently installing in my car. Haven't had the chance to hear it yet but I suspect it will be loud. I might have to get some baffles similar to what is pictured.

Yes you will likely want to tone it down. The 2/GT3-S were built custom for clients who wanted it super aggressive. Shoot me an email when the time comes as there are a couple options.

Having had both mufflers to compare, I would have loved to keep my M&K GT3. Yeap it was much lighter, and yeah the construction was artistry, an artistry comparable to the SSIs that they were attached to. Even had the polished tips which I loved.

That being said, talk to Brian if you're leaning towards buying his product and make sure you get exactly what you need. The sound is sound and not an issue for me although it was considerably louder and had an awful drone. I liked it, but no one else (especially my wife) did.

I wouldn't have gotten rid of it only for the sound issue though, the problem for me was that the torque band moved WAY upstream and would have been the kiss of death for AX events which is why I focus on. My car is a stock 3.2 with improved intake and a SW 93 octane chip. In other words, a mild upgrade and what 90% of us that go a little beyond stock do to these engines.

I think given much more restriction, perhaps even blocking off one one outlet from the get go would have been the way to go, but it wasn't what I bought.

I wound up putting on the Dansk GT3 from Patrick and as ugly welded, poorly painted and cheaply steeled as it it, it just worked right out of the box as is and it completely transformed the engine to exactly what I was looking for. Sound wise, it's not at loud, there's only a minimum of drone in a very tight 300 RPM range just before it hits 3k but it's only noticeable if you're looking for it.

I wish I could have kept the M&K but I think I needed a hell of a lot more engine to sport it than I had.

I've been eyeing this muffler too.



I think it might be too open for my 2.7 but nice if I upgrade to a 3.0 or 3.2 later.

I've watched this video a dozen times. LOVE the sound.



I thought I saw it on Pelican, but the pp search is maddening. I haven't been able to find it since.
