Hi I’m Justin with, and I’m taking a closer look at Pypes long tube headers, fitting the modular 4.6L motor found in all 96-04 manual Mustang GTs. Taking a closer look at these long tubes you’ll first notice the polished 304 grade stainless steel construction, and the mandrel bends, which is going to help improve your exhaust flow. In addition we’re looking at 1-5/8” tubing, from the OE style flanges, all the way down to the collectors, that do feature pre-welded bungs for your O2 sensor, as well as an EGR bung. As you can see, these long tubes from Pypes also feature a nice bright finish, which of course will look good under the hood, but is also going to resist any possible corrosion down the road, so these headers will remain looking good for years to come. If you’re not familiar with long tubes then you will need to keep a couple of things in mind. First, you’re going to see the biggest gains in both horsepower and torque, which is obviously a plus, in addition, you should notice a change to your exhaust note. Now these extra gains do come with a little added work, for one, the install is slightly more involved, and you will need to modify your mid-pipe. In this case Pypes recommends the use of their shorty H-pipe, just for proper fitment and for best performance. When it does come time to install these headers it would be a great idea to leave yourself a full day just to tackle the job. Now again in order to make this a 100% bolt on affair you will need to use Pypes short H-pipe to get everything bolted up properly, otherwise you may need to get some custom work done by your local exhaust shop. In the end, what you can expect when using pypes polished long headers on your 2 valve, is a noticeable gain in both power and sound, all for a price that’s very competitive with other long tube options. As always, you can check them out right here at

Durable Construction. Manufactured from 1-5/8" mandrel bent 304 stainless steel tubing for strength and improved airflow, these Pypes Long Tube Exhaust headers feature a one piece 3/8" thick header flange for additional strength and an OEM fit. Pypes headers are then polished to a bright finish for impressive under hood styling.

Recommended Upgrade. To realize the full power potential that these Long Tube Headers have to offer, AmericanMuscle recommends a Bama custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

Application. These Pypes Polished Long Tube Headers are designed to fit the 1996 to 2004 GT Mustangs with a manual transmission. Pypes long tube headers require a shorty mid pipe in order to install correctly. Pypes recommends using a Pypes shorty H-Pipe for the best performance gains (see drop down option above).
