Which exhaust setup sounds better? 🤔

[@romansetgo95]

Dundon

[@cYaNiDE881]

Definitely the Dundon!

[@AlexiaAnnastasya]

Dundon by a mile, what a sound! :)

secret weapon

[@UncleFjester]

I'm wanting a quiet EV ..... GT3 RevS

[@Lukas-sv4ft]

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

[@102Crypto]

I prefer the Akrapovic sound because it sounds more crisp and not that high pitched

[@bustjanzupan1074]

@@102Crypto And Because it gives More Torque !!! 🙂

[@the_mcmartin]

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

[@M855A1]

for me the opposite

[@JCviggen1]

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.

[@aasishwarsaravana5748]

Performance at the expense of the glorious exhaust sound!

[@santi3991]

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

[@recon1673]

The Dundon has issues at about 2 to 3k RPM in the sound.

[@khrisbharath752]

Spine tingling

[@photon4280]

Nice overlay work with the speedometer during the rear cam

[@Virvum_Juggernaut]

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.

Love u from Nepal❤❤

[@5555petros]

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

[@sveeny]

These Porsche Flat Six sound so damn good.

[@BxTpr]

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

[@mikesmith7496]

looks great without the rear bumper!

[@WDLC1911]

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

[@plasticfoodsyt]

Eargasm 🤤😩

[@102Crypto]

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

[@Tetrahedonism]

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

[@wrxzboost]

akra looks nicer, dundon sounds better.

[@Spatack09]

😍😍

[@ProJnr12]

Same as Golf 7.5 R

[@KNSRK_]

DUNDON!

[@07ring07]

👍❤

[@BubbaSmurft]

Megaphones win by an ear.
