Unfortunately, when most factory exhaust manifolds are designed, more attention is paid to how easily they fit in the engine compartment instead of how they affect performance. Most manifolds are inefficient because more than one cylinder dumps exhaust into the same small space. Their restrictive shape chokes your engine, bottling up hidden ponies that are just waiting to be released.
These long tube headers enable your engine to develop its potential in two ways. First, the large diameter individual tubes allow the exhaust to flow unobstructed from the cylinder head, and second, the length and diameter of the tubes are optimally designed for the engine’s exhaust pulses. As the exhaust pulse travels down the header tube, its momentum creates a vacuum behind the pulse as the exhaust valve closes. This helps “scavenge” the remaining exhaust from the combustion chamber as well as help draw the intake charge in. The increased flow and scavenging results in gains in horsepower and torque, and performance improvements you can feel.
But all these performance improvements mean nothing if the headers rust out in a few years. Flowmaster ensures that this won’t happen with Scavenger Series Elite headers by constructing them with durable 409 series stainless steel and then coating them with a high temperature resistant ceramic coating. 409 stainless steel is particularly suited to exhaust systems because it resists both atmospheric and exhaust gas corrosion, and the ceramic coating will ensure your headers remain an attractive part of your engine bay.
Scavenger Series Elite headers are manufactured with rigid 3/8” thick flanges to ensure perfect sealing at the heads, and they feature Flowmaster’s leak-free ball and socket flange to connect with your exhaust system. There’s no need to mess with leaky 3-bolt collector flanges and gaskets. Your headers come with gaskets, hardware and everything necessary for easy installation, including detailed instructions. They’re backed by a 1-year limited warranty against defects in materials and workmanship, and they’re proudly manufactured in the USA.679.00Brand: Flowmaster Part Number: 814227 UPC: 700042026425
Flowmaster® has its roots in solving the engine noise problems encountered by California racers in the 1980s. In 1983 Flowmaster’s founder, Ray Flugger, created his first patented design of racing silencers, which dampened noise with minimal loss of power. Ray attached handles to ease carrying the square shaped race mufflers through the race pits, and the mufflers became known as the "suitcase mufflers." Today, the innovative Flowmaster mufflers are the result of years of development with top race engine builders, thousands of hours of dyno research and "real-world" on-track testing.Flowmaster® - Scavenger Series Elite Headers Reviews (10)Customers' rating: 5 OF 5APPEARANCEEASE OF INSTALLATIONPRICE/VALUEQUALITY(4.5)APPEARANCEEASE OF INSTALLATIONPRICE/VALUEQUALITYMustang Wake Up| Posted by Daryl P. | 2013 Ford Mustang (League City, TX)
The Flowmaster Outlaw Series exhaust is exactly what I was wanting! The sound is great and makes the car sound like a 5.0 L. Very deep growl but not too much! The fit was very good, but the weep holes in the tips are not perfect on the bottom, but I think it will be okay!Was this review helpful for you?

This exhaust system is not from the cat back, there is a piece of pipe 22.5" long that they don't include. My muffler had a 11" piece of pipe welded to it, they illuminate it, witch is not a problem. I would have gave it a 5 star if not for that pipe.Was this review helpful for you?

I installed the Flowmaster Delta 50 on my 97 Explorer because my old, original muffler had seen better days. What I didn't expect was for my vehicle to have such a noticeable increase in horsepower! I can't say enough about how great it sounds when I'm driving down the highway. It has a nice rumble that's noticeable but not too loud.Was this review helpful for you?

I recently ordered a Flowmaster muffler from CARiD and the experience was a very good one. The order was filled very fast and sent. I received it in no time at all. It was in great condition and sound great on my truck, and I couldn't beat the price.Was this review helpful for you?

I got my muffler in good timing, had it put on. Sounds good! I have a TV in my truck, and while driving, I do not hear it in the cab. A great muffler, a little more torque. Haven t tried top end yet.Was this review helpful for you?

CARiD.com was absolutely superb in helping me find the correct exhaust. It has a clean rumble and it fits perfectly in my brand new 2013 4-door ford f-150, just like they said it would.Was this review helpful for you?

Installed this Force 2 cat back system on my 2012 Focus SE. Without a doubt, there is more airflow, throttle response, engine note and horsepower... I would recommend this system to enhance the direct injected 4-cyl. that Ford has to offer...Was this review helpful for you?
