Product Details

The JBA Performance Exhaust 6655SJS long tube headers are engineered for maximum horsepower and torque gains on 1967-1970 Ford Mustangs equipped with 390, 427, or 428 Cobra Jet FE engines. Featuring a premium silver ceramic coating and 1-3/4 inch mandrel-bent primary tubes, these competition-ready headers deliver dyno-proven performance throughout the entire RPM range.

Key Features:

  • 409 stainless steel construction with silver ceramic coating for superior heat resistance and durability
  • 1-3/4 inch mandrel-bent primary tubes for maximum exhaust flow and high RPM efficiency
  • Extra-thick 3/8 inch CNC laser-cut flanges prevent warping and exhaust leaks
  • Patented JBA Firecone® merged collectors improve exhaust scavenging for increased power
  • Oversized exhaust ports accommodate ported cylinder heads
  • 3-inch collector diameter with ball and socket flange attachment
  • Includes high-quality hardware, gaskets, and detailed installation instructions

Application Notes: Designed for 1967-1970 Mustang with 390/427/428 FE engines and Cobra Jet cylinder heads. Fits manual steering or aftermarket rack and pinion conversions with 4-speed or C6 automatic transmissions. Will not fit standard 390 cylinder heads. Requires JBA power steering drop-down bracket (sold separately) when used with factory power steering. Legal for use on 1974 and older non-catalyst equipped vehicles. For closed course competition use only.

Each JBA long tube header system is precision-engineered to maximize ground clearance while delivering professional-grade fitment. The silver ceramic coating provides excellent heat dissipation and a distinctive appearance that withstands the harshest environments.

Excellent service and fast shipping. A seller I would do business with again.

I ordered an AEM intake for my F-150 on Christmas day and received it on the 29th. I would absolutely recommend this site to anyone looking for car parts - they had the lowest price by far and shipped fast. Great job!

Very easy experience

very good low price, had a slight issue but customer service was amazing,. i would recommend AutoPlicity to anyone because of that, good prices, good customer service,. (meaning trust worthy) why not :). A+++ Service will buy from again!

Best price and super fast shipping. Only issue was that their online order status system was really far behind! The system said my order was "pending" and it had been shipped. Later it said "processing" and it was on my doorstep. Not a big deal and certainly better than the opposite (they tell you something has happened when it hasn't) and doesn't keep them from being a 5 star seller in my book.

Great price and quick shipping!

Lowest price on the Internet, good packaging and fast shipping.

Excellent service!!!! Ordered another part from one of those big chain stores three days earlier and got your part one day sooner than theirs. Thanks. Excellent customer service. Wouldn't hesitate to use you again.

Great product and speedy service!

Couldn't be more happy with my product. I ordered from Autoplicity because they were the cheapest price around and I received my order within 5 days. I have installed the cold air intake and couldn't believe all the extra power. I am very pleased with the entire transaction.
