Dundon Exhaust sounds more like a GT3 Cup, Akrapovic sounds just a bit louder than stock

[the_mcmartin]

Dundon wins. Smooth and doesn't hurt the ears.

[santi]

The performance difference goes out of the window with how glorious the Dundon sounds

[JCviggen]

Based on the graphs the Akra would be slightly faster. Same peak power but more area under the curve over the useful RPM range. I've seen the same thing with the Dundon headers on my car - amazing performance the last few hundred RPM but at the expense of a torque/power loss between 5 and 7.5K RPM.

The Dundon setup sounds so much better than the Akrapovic setup that the white GT3RS sounds as if it’s redlining @ 2, 000RPM beyond the 9, 000RPM redline of the yellow GT3RS.

Nice overlay work with the speedometer during the rear cam

[Crypto]

This sound gives me goosebumps all over my body, especially the Akrapovic one

[BxTpr]

How are you guys getting around the GPF/OPF with the headers ? Tune?

[cwalden]

Dundon almost sounds like a motorbike. Awesome

[sveeny]

These Porsche Flat Six sound so damn good.

[PeterSmit-zz]

Akra the better system. Get more power at 3000 rpm. That’s where you need the power in the low end. Also Akra is cheaper.

[petros]

I'm more interested in the red 500 in the background at 0:16. What's little guy up to back there?

[wrxzboost]

akra looks nicer, dundon sounds better.

[salemalkaabi-dx]

Confirm dundon only mini crack pipe or full exhaust

[jasonm.]

Just do a muffler delete and straight pipe. Just did it on 2007 325i. Sounds sick

[Tetrahedonism]

Do they also come in unobtanium these exhausts!? Only the best for my GT3 RS you see😅

[WDLC]

Worked in Powertrain Sound Quality for seven years and both are too “raspy”. An additional resonator would make them both sound _a LOT_ better.
