This 3" Downpipe is good for those individuals looking to make over 500hp.  If you are looking to make less than 500hp, save yourself time and money, and go with a 2.5" downpipe (which we also carry).  
 
Comes just as you see pictured:  With flange, and donut.  Ready to install!    If you'd like new exhaust springs and hardware, we carry those parts in stock as well.     If you don't see those hardware items listed on our site, send us a note and we'll get them posted.
