well, in the seller's defense, it reallly does sound like a turbo.

AND they were used on the cars in the Fast & the Furious. you can adjust it to have a turbo effect or a supercharger. anyone know if i put one in each of my csvt's tailpipes, will that create a "twin turbo?"

i think im going to email the seller and ask him.
heck, i could adjust one to sound like a turbo and the other to sound like a supercharger! when i go to the track, people will think i have BOTH! pure madness
