It's my first time here. Happy to meet everyone. Which aftermarket header would you recommend for street applications?

 

Some people dont like um cuz there hard to install, but I had a nice 25hp gain out of my mac longtube headers and x-pipe. plus they sound cool!

 

Long tube (full length) headers will always bring back the biggest gains in HP but are much more complicated to install as you also need to modify your exhaust system for proper hook-up. Clearance under the car may also sometimes be a bit of a problem. Try these for the most bang for the buck with a minimum of hassles:

They still can bring back some good gains in HP and smoother running overall. Any car with headers will also increase the mileage a bit as the exhaust gases can move that much more quickly and efficiently through the system. Good luck with your choice and enjoy your Stang.
