The sound of twelve nearly completely stock Ferrari 360 Modenas (save for exhaust) suddenly gunning it at the starting line 3/4 of a mile away at Watkins Glen. The sound is absolutely spine chilling when resonating through trees.

 

My 5-way tie:

*The sound of a new Enzo being run to redline in 1st, 2nd and third. (Driving, behind the car)

* The sound of an F355 in one of the many tunnels between Italy and Switzerland (Following directly behind the car at the time)

* The sound of a MkIV TT Supra w/ ±550whp. (From the passenger's seat, targa roof open)

* The sound of a 993 911 Turbo passing at 180+ on the Autobahn between Ülm and Frankfurt. (In a 406 V6 Sedan at about 110mph)

* The sound of a 1989 Peugeot 405 Mi16 from 2500 rpm on to the 7400 rpm fuel-cut. (From the driver's seat h: )

 

i like the sound of a freightliner going down the highway ripping it with turbo!

 

hands down the monsterous v10 of a dodge viper

 

i like the BMW 323i with UUC TSE II:thumbup:

 

LS1/LS6 GM sounds awesome. LT5's sound awesome, too. Chrysler's 318 always sounded nice with a good exhaust, not having to mention the 426. The 318 is still my all-time favorite old V8 though from that era.

SRT-4's and PT turbos sound awesome too. Very nice. I like deeper american sounding cars I guess.

 

In all truthfullness, I love the Mopar big blocks just as much as a the wail of a Ferrari 8 or 12, just as much as I love the sound boosted fours and sixes. It's impossible for me to pick a single favorite. h:

 

i like my car when vtec hits (b16a2 w/ aem noisemaker) and i love the sound of the STi from the drivers seat at about 1800, very deep. people say it sounds awesome when im on it from the outside....ive yet to hear it :dunno:
not saying these are the best i just like them.

 

all the late-model McLaren F1 cars
all the late-model Ferrari F1 cars

Street car though... I'd say a 360 or 355, as well as the Viper. Sheer cargasm material.

 

Ferrari F355
N/A built-up BMW E36 M3 with :dunno: exhaust
M5 with BB Triflo exhaust
