You're going to have a decision to make when it comes to selecting a new set of headers for your Mustang-- shorties or long tubes. Well, I'm going to go ahead and put it out there, before we get into the differences, that long tubes do make more power and torque versus a shorty header. So why would anybody ever purchase a shorty header? There's actually several reasons.
We all know that factory manifolds are restrictive and not the best for making power. Shorty headers do remove most of the restrictions and add in larger diameter tubing. That way, you get the extra exhaust flow, which is going to give you your more power.
Shorty headers also offer a lower price point compared to long tube headers, and they're a direct replacement design, meaning they'll bolt directly to your factory cylinder head and to your existing mid pipe; you don't have to change that out. Also, another big plus is you'll have plenty of working room later, down the road, when it comes time to service your Mustang, be it a simple starter replacement or a complete clutch job.
If you're the type of person that likes to eke out every last horsepower from your Mustang, then you need to look at the long tube header design. The downsides to the long tube header revolve around the fact that they take up more space, meaning there's less room to work later down the road when it comes time to service your Mustang. This could make a simple starter swap a lot more compact, and it sometimes even requires that you loosen or completely remove a long tube header to service your transmission or clutch.
Luckily, the majority of long tube headers available today will fit your Mustang without any major modifications, meaning you're not going to have to beat up your frame rails or floor pan to get them to clear. Long tube headers allow the exiting exhaust poles to help pull in the incoming air fuel charge, also known as the scavenging effect. This is where the majority of their added power and torque come from. Regardless of the header design you choose, latemodelrestoration.com is your choice for Mustang exhaust upgrades.
I've had these for about 4 months now, by themselves they make 12-15 hp. add an offroad x and they make 15-20 more peak hp. Combined #'s are 30-35 hp. That's long tube power without the hassle of longtubes! The sound will change you get a little more growl. Install difficulty is the same as longtubes, but worth it if you want to keep your cats. A quality product! Now go get a pair, or get used to seeing my tail lights......
