i have tint but i dont know if i want to do it my self or have some one else do it. I dont want it looking like all the tuner cars that have bubbles and cracks in the tint cus they did it themselfs. No noticable hp gains with the exuast i just wanted to hear the car when i drive it. Not to loud its a nice tone. I had a bronco with the 5.0, headers, highflow cats, and glasspacks... that was loud.:smiley_thumbs_up:
