my 88 n/a smells so horrible, is it normal since i am running downpipe presilencer RB product? also it smokes whenever i rev redline.....

 

The smell is normal for a car with no cats. As for the smoke, what color is it? I suspect that if it only happens at redline, then its the oil control rings going out. The only fix is rebuilding the engine, so you're just gonna have to deal with having an engine that smokes.
