engine sounds loud in my regular cab

I have a 1996 regular cab 2.4L 4cyl. I have had for a year now and I cant to find out why it is so loud in the cab. ive heard it drive by me and heard the engine outside of the taco and seems quiet. I just need some help to make my taco sound like she is purring instead of roaring.

 

Do you have a body lift?

 

nope. just standard everything. nothing special

 

I don't know man, its going to be louder inside most moving vehicles than it is hearing it drive past you...i.e. road noise. Are you sure it's the engine or just road noise or maybe something suspension/tire related? Also, manual or automatic?

 

Sure you don't have a doughnut gasket going bad. It would sound like it was on pass side glove box.
