i had put side pipes on my 77 grand prix back in the day ,early `80`s (if i can find the pic i`ll post it ), they were cool at first and really woke up the 400 that was in it ,(along with the neighborhood), but the car was my daily driver and the pipes got to be a major pain !! even though they had a shield on them i still got burned occasionally , and i couldnt " lay low " when the cops were around , and the gravel and road debris constantly being thrown up on them was a problem , anyway , i ended up takeing them off and never missed or wanted them again since !! just my experiance with them that i thought i would pass along ,,
