It makes a roaring sound.
Whoa, too much information.
Is it tan? All tan Tacomas roar. 
more info please. I too have an 08 tacoma.
A couple of the forum members asked the OP for more information a year ago, so I wouldnāt hold out much hope of the OP providing it at this point.
Why donāt you start your own thread, and be sure to include as much relevant info as possible, such asā¦ odometer mileage and exactly WHEN it roars?
I once saw an '08 Tacoma. Can I get some more info as well?
Yes , more info . I find it ridiculous when people call a Toyota Tacoma ā Taco '.
Hmm, would that make it a āstreet tacoā?
If I bought a street taco and it tasted like any part of a truck, Iād demand a refund.
Even if it was filled with car-ne asada? 
Have you seen those older Toyota trucks where the tailgate says āYodaā . . . ?!
I find that even more annoying than āTacoā . . .
Even! The meat would probably be in that foot-high pile of Jack-in-the-Box wrappers on the floor!
I think 2020 has made us all loony. And I think thatās just GRRRRReat!
