Finally someone called to come see the blazer, is a 1997 chevy blazer s10 2 door, i pieced the y pipe because it was crushed, new fuel pump, got a universal cat on it, many other parts, i noticed when i push down to accelerate it makes a loud sound sound like a old truck, and sometimes sounds like it sucking air back in? biggest thing is getting the loudness down or is it normal haha i cant remember what my blazer sounded like since i bought it because it always had problems... just need to get rid of it cost me way to much money
