Brand new pipe, it was simply just too loud for me; sounded nice, just too loud. Anyways, i have the original boxing/instructions and everything you need to bolt it up to your mustang. I'll throw in the MIL eliminators as well so you dont have to bother with the CEL. 190+shipping including the MIL eliminators (you will need these unless you have an SCT tuner) and 150+shipping without them.
By the way, the install takes about an hour and i wouldn't mind at all stepping you through the process so you get it hooked up in no time, correctly. My e-mail is [email protected]
