Living Legal

I have an ’02 GT with 110,000 miles. I am looking to purchase headers to increase some power without ruining my fuel efficiency too much. So I’ve been looking to get headers and a catted X-style mid-pipe. I live in California, so I want it to appear, at a glance, legal. I already have a few mods, including cold-air intake, 70mm throttle body, aftermarket plugs, and Borla Stinger Cat-Back exhaust. Will the headers work on a daily driver, and will they last? Will the catted X-style mid-pipe be worth it? I plan to get a flash tuner once all this is in.

Mpks92, headers will work on your daily driver. Headers and an X-style mid-pipe will give you the best performance gains and will actually increase your engine’s efficiency, which should give you better fuel mileage. The most efficient headers would be long-tubes (although not CARB-legal), and the most durable and long lasting would be stainless steel headers.

Endless Chatter

The Ford dealership recently replaced the clutch assembly at 55,000 miles. Since the replacement, the clutch chatters in First and Reverse if the rpm is below 1,500, and the drivetrain makes a noticeable oscillating humming noise in Third gear at about 50 mph. The car has been back to the dealer twice, and they continue to tell me these problems are normal for the updated clutch that was installed in the car. Is this actually the case or is the dealer making up stories so they do not have to fix the problem? Also, the vehicle is in need of new shocks and struts. The car is mostly stock, and I am wondering what new parts I should get to replace the old.

Stu, if they replaced it with the stock assembly, then it should have no chatter or noise. If you went with an aftermarket or upgraded clutch assembly, then it could be a issue with the disc and or pressure plate. I would ask the dealer to fix this issue in either case. For shocks and struts, I like the Bilstein HD Series, a quality damper that greatly improves handle and ride. If you’re looking for adjustable shocks and struts, you can’t go wrong with Konis.

Fox Tails

My name is Alex, I’m 19 years old, and restoring my first car from the ground up. I have a ’79 Mustang hatchback, and I’m running into a problem with the taillights. I despise the look of the stock ones, but I have found an aftermarket set for an ’89 that I like, and I was wondering if they would bolt right up or if I would have to do some fabrication to the car. I’m also look into other late-model Fox-body trim items.

Via the Internet

Alex, ’89 Mustang taillights are a simple bolt-in with no mods necessary. It’s a great upgrade to give your ’79 Mustang a fresh look. All Fox-body vehicles share many trim and mechanical parts. Plus, there is lots of aftermarket support for Fox-body Mustangs. AmericanMuscle (www.AmericanMuscle.com) and LatemodelRestoration (www.LatemodelRestoration.com) are a few companies that offer everything you need.

Six or Eight

How can I modify my ’12 Mustang V-6 to increase horsepower significantly to run mid-13s? I was told any re-flashing is not really worth the cash. Would it be wise to just trade up, or can I save some money by upgrading what I have?

Via the Internet

Ron, the 3.7 V-6 is great platform for upgrades. A tune will increase power noticeably and is worth every penny. Exhaust, cold-air intake, throttle body, and gears will all increase power and performance. Get yourself a tune, along with these upgrades, and you will have an economical performance car that can run mid-13s all day long, along with saving yourself some money for trading up later.

Stock as a Rock

I have an ’01 Mustang GT with a K&N air filter as the only mod. I have had it for over a month now, and I’m looking for ways to add horsepower without supercharging it. I have looked at throttle bodies and gears, and I’m just not sure what to get specifically. I’m open to suggestions.

The first thing I would suggest is a tune; it will give biggest bang for your buck. Throttle bodies, cold-air intakes, and long-tube headers will all increase power individually, and when combined, they add significant power gains. What’s good about these mods is you can add them as your budget allows and have your tune updated as you upgrade. Gears will also give an increase in performance you can really feel. I suggest 3.73s for a stick and 4.10s for an auto.
