Thanks! I am seriously thinking that could be nirvana vs anything else out there. Especially, in the price range. And going back to a manual would be cool. GT3 + TT seem to be a great combination.

Great write up Sean. I'm absolutely love the street headers and black muffler on my 2016! Great sounds and on the .1 RS, nice mid-band power increases I think based on my seat-of-the-pants dyno. My car is still struggling with CEL faults unfortunately. Jamie has been great trying to help, and I certainly hope we get it figured out soon. Wish I had gotten that cool Dundon hat with my full order.... may have to talk to Jamie about that little commission . Enjoy it in good health and I look forward to hearing it in July.....

Damn you Sean!!! I’ve been getting antsy looking for a bit more power. And similar to you, I’ve had numerous exhausts on my GT’s........HANDS DOWN...the best was the Dundon system.

I am guessing the mountains are now open to play? Was planning on a mountain ride, but was hearing the blue ridge west was kinda shut down, roads closed etc etc.

Its hard to believe there is something that sounds better than the GMG.

I need some video.

Definitely go with the crack pipe and cup headers, most amazing thing I’ve ever heard on a street car!! Even able to talk with the wife when on a leisurely drive.

They both sound amazing - I've reached the end of the internet on gt exhaust videos - it's hard to hear the difference in any of these exhausts in a video. Stock, center delete or headers. I will try to get some though.

is the good or bad thing?

and the wife won’t notice when she rides in the car. My wife can’t tell there is an exhaust on my car except for the giddy smile on my face

Seth Thomas

well come drive my car sometime and see which you like. You know where I live since you stalked me a couple weeks ago. 😂

Here is mine with GMG.

It really isn't that hard to believe. Trust me.

Sound is subjective. Horsepower and torque are quantfiable.

Fair point...for me the RS with GMG is pretty damn good.

The power difference is massive, not slightly better, but massive. My car has the full intake, full headers, cats and the Quiet Dundon muffler (it is not quiet, it is less loud).

The engine is angrier, it pulls like a bigger engine from everywhere in the RPM range, and the last 3k rpms are so strong that I cannot floor the car anymore on highways. A friend with a 458 drove my car and he said his 458 is slower than my car, he has 20k miles in his 458 since 2012 so plenty of seat time in that car.

The car gains in the low range, mid-range and upper range, despite of the quiet muffler being heavier (but it also doesn't crack like the stock center muffler, and I have cracked them), the whole system is lighter due to the elimination of the useless side mufflers (which Porsche finally eliminated in the 991.3 GT3RS).

I have the optional titanium tips pictured in the Speedster above. I asked for mine not to be pre-burned, as I like my own driving to add the colors to burned Titanium in a very unique way, so my Ti Tips have no equal out there. Every Dundon muffler owner should have the Ti Tips (and they are lightttttt).
