Product Description

Pypes Off Road H-Pipe
Increase horsepower, torque, and sound in your 1999-2004 Mustang GT with this off road H-pipe from Pypes exhaust! The factory mid-pipe on your 1999-2004 Mustang GT has four catalytic converters that restrict flow and performance. This mid-pipe removes the cats to drastically improve flow over the factory exhaust. Not only does it increase flow, but it also adds a sound that is sure to turn heads!

Pypes Quality Exhaust
Pypes constructs this H-pipe from 2.5" mandrel bent tubing for uninterrupted flow and sound. Pypes utilizes 409 stainless steel that resists corrosion and road debris. The three piece design allows you to easily adjust the lead pipes going from the headers for an easy installation.

Installation Note
It is recommended that you buy a set of MIL eliminators to turn off the rear O2 sensors to prevent a check engine light.

Emissions Note
This mid-pipe does NOT have catalytic converters. Therefore it is intended for OFF-ROAD use only and will not pass emissions testing.
