hey guys I just ran vs a 2.5L nissan altima, the guy won me but he said he added some headers, some ***** ass exhaust the ones that you can fin in pep boys or auto zone, he also has a chip , C.A.I and a turbonator bvut the moment he accelerated the care sounded from a muscle sound like a v6 charger and then sodenly the sound changed and it sounded like if he had a turbo at 24psi the turbo sounded so dam loud I got scared at that thing but then later he showed what his car got and it diodnt had a turbo I just had a air filter , and the headers ehaust etc...... he told me that the sound it made was cause of the air filter and the turbo nator but I think that was bull I think the sound was made by the exhaust maybe he installed a ehxaust that sounds like a turbo Ive seen then on internet but I really want to know if the turbonator make the airfilter sound much louder, thank Alejnadro from Mexico.
