Exhaust Comparo from the DC Group Buy

dhoggm3 · 01-24-2010, 05:59 AM

Yesterday at the Powerchip GB there were 7 M3's with a variety of AA cat-back, Eisenman Sport/X-pipe/HFC, and Eisenman Race /X-pipe/HFC. I may be forgetting one other. We gave rides and listened inside and out.

Loudest: As you'd expect, the Eisenman Race /X-pipe/HFC. This setup will really get your attention, inside and out, and is not good for a daily driver. Outside it has a staccatto sound on top of the rumble that some liked, some not. Very fun.

Eisenman Sport: Loud on startup but when the idle settles down, very nice rumble and sporty sound, and quite livable for a DD. Did not listen to it inside but Ben says the HFC's definitely add to the volume.

AA cat-back: Never thought I'd say this but it was the quietest (no HFC plays a big role here). One of us noted it is "higher-pitched and sounds the most F1 like". I call it more Ferrari-like but you get the picture.

Others from the GB, please help fill in the blanks and offer opinions.

No, sorry. This was done at my house and it would not have been good for neighborly relations to have done a video. Many exhausts yesterday were quite loud.
