Product Description

Mustang MAC GT40P Shorty Headers
Bolt on more horsepower and torque to your 1994-1995 Mustang 5.0 with MAC's GT40P shorty headers! When installing GT40P cylinder heads, you quickly realize that the spark plugs are at a different angle, which makes it difficult to install spark plugs and wires with your factory exhaust manifolds. MAC designed these shorty headers specifically for GT40P cylinder heads, so your plug wires don't come into contact with the header. MAC's shorty headers feature 1-5/8" primary tubes that greatly improve exhaust flow, and allow your engine to breathe. These primary tubes flow into 2-1/2" True Fit collectors that eliminate the need for collector gaskets. Along with the performance gains, you'll experience a new exhaust tone that gives your Mustang a new attitude!

MAC Quality
MAC has produced exhaust products for over 45 years, and the quality and experience shows in these GT40P headers. Manufactured using mandrel bent, 16 gauge steel; these headers are precision fit and built to last! Single port flanges prevent any loosening that could occur with solid flanged headers. 1-5/8" primaries flow into 2-1/2" collectors that fit stock and MAC mid-pipes. MAC's polished ceramic finish is applied to the headers and is sure to brighten up your engine bay, as well as reduce engine bay temps! A set of header gaskets, header bolts, studs, and flange nuts complete this kit to make installation quick and easy!

Fitment Note
These MAC shorty headers will ONLY fit GT40P cylinder heads.

Emissions Note
These headers are designed for off road use only. Not legal for street use in California.

-Fits 1994-1995 Mustang 5.0 w/ GT40P cylinder heads.
