If you are looking for a more aggressive sound and more power from your 1999-2004 Mustang GT 4.6L 2 valve, this Pypes off road x-pipe is exactly what you need. Not only will this mid-pipe free up some extra ponies under the hood of your Mustang, it will also add a much more aggressive exhaust note. Direct bol-on application makes this modification a no brainer for any Mustang enthusiast!
2004 Mustangs will need O2 extensions for the rear O2 sensors.
For off-road use only! Deleting or bypassing factory emissions equipment is illegal for use on public roadways.
I BOUGHT THIS PYPES X-PIPE AND I LOVE IT. EASY INSTALLATION! THE CAR SOUNDS AWSOME WITH THE PYPES X-PIPE AND THE FLOWMASTER 40'S I GOT FROM LATEMODEL RESTORATION!
Yes, I would recommend this item to a friend!

I ran this part on my 99 GT, this made the car sound awesome!!! Fitment was perfect ( after using a half a can of wd-40 to get the stock bolts loose), and no loss of ground clearance. Make sure to get the Mil eliminators when buying this unless you have a tuner for the check engine light.
If you're working on a Latemodel Mustang, Pypes' innovative products, and superior quality allow you to make your exhaust purchase with absolute confidence that you are getting the best materials, best fit and best value available anywhere. Pype's aftermarket performance exhaust components give your Mustang more horsepower and torque while adding a great new exhaust tone. These x-pipes, h-pipes, headers, and cat back kits are direct fit and 100% bolt on, making installation quick and easy.
I've done the majority of my aftermarket mustang parts shopping at American muscle, recently finding out about this website I'd just like to say it is a great experience to shop here, the lay out is easy and simple to navigate, and you have thousands of parts that no other website has. The shipping is very fast and all te updates are great. I will be doin much more shopping with y'all, so thanks for being so badass haha
