2004 Mustang 5-sp 3.9 Long Tube Headers or Shorties?
New to the forum and I have an 04 3.9L with a five speed, I was looking to put some headers on and was wondering which ones I could still use with the factory converters. Current exhaust, is dual at the y pip with thrush welded mufflers and stock manifolds.
