Special Notes:
1) Drag pipes are not recommended for use on the street.
2) These pipes have less ground clearance than original equipment and may scrape on hard right hand turns. Do not use these pipes unless the front end is extended at least 4" longer than stock or serious injury may result.
3) See page 247 for P-clamps and frame rail clamps to install these pipe sets.
4) See pages 349-353 for photos of the heat shields for these pipe sets.
