Product Description

Increase Performance
When your'e looking to increase horsepower in your 1999-2004 Mustang 4.6L, but worried about failing emissions testing, this Magnaflow catted X-Pipe is the answer to your problem! With two integrated high flow cats, this X-Pipe cuts down emissions, while improving exhaust flow giving you more horsepower and a more aggressive exhaust tone!

High Quality Construction
Magnaflow's Mustang Catalytic Converter is designed to do two jobs: Reduce Emissions and Improve Flow. The emission reducing task is taken care of by two high-efficiency ceramic catalysts that use heat and a precious metal coating to burn off harmful elements. Flow improvements are accomplished by utilizing fast-flowing mandrel-bent tubing and incorporating MagnaFlow's Tru-X crossover pipe that replaces the inefficient factory h-pipe.

Other Features:
- 2.5" mandrel bent tubing
- Designed for easy bolt-on installation
- Requires no cutting or welding
- 100% all stainless steel
- Dyno tested and proven to make power
- Easy to install
- Great sound - Has a smooth; deep tone
- Performance gains in horsepower and torque

5 Stars   Great Fit and Sound
By on 8/1/2017
Image uploaded by Timothy W. Installed on my 01 Cobra Convertible. Fits great and sounds amazing with the Magnaflow cat back. Only issue I had was that the box was beat to heck by the shipping company and had to tweak on one of pipes to restore the connection. Also, the nuts were not in the box, but a call to Magnaflow's tech line solved that. They were super helpful and friendly.

Yes, I would recommend this item to a friend!

4 Stars   Shorter than stock

It is a nice piece but it is a bit shorter than the stock H-pipe in a Mach 1. This meant that I had to readjust my flow master cat back. Overall a nice piece with a nice sound

Yes, I would recommend this item to a friend!
