Product Questions

So these reduce down to a 2.5 outlet after the cats.. What bolt on cat back system could I use that would keep the exhaust 2.5 all the way to the tip?  It appears to me that the ARH xpipe cat back reduces again to 2.25.  Is that accurate?

Asked by: goatranced
Correct. Any of our cat-back options will work with these headers, all of which are at least 2.5" all the way to the tips.

Do these require a tune?

Asked by: Earlgizzle
Without a tune, your car may throw a check engine light due to the increased exhaust flow and new location of the oxygen sensors.

Do these come with an emissions # and are they legal in CA?

Asked by: B Stang
They do not come with a emissions #, therefore they are most likely not legal in CA. But we do not keep track of laws that change from state to state regarding the legality of certain parts. We try to offer you the same information that is provided to us.

American Racing Headers Long Tube Headers Direct Connect 1-3/4" With Catalytic Converters Stainless Steel GT 2015-2017 Video Transcript
By Bill Tumas: We’re here with an American Racing header's direct connect long tube header kit fitting your 2015 through 2016 Mustang GT. This direct connect header kit from American Racing is designed to fit all 2015 through 2016 Mustang GTs. It starts with a set of the long tube headers with a 1 and 3/4 inch primary, 3 inch laser cut phalange, and a 3 inch collector. From there, it goes into a 3 inch stainless steel mandrel bent mid pipes that include a high-flow 200 cell substrate catalytic converter. The American Racing headers are made of 304 stainless steel front to back and quality is evident throughout. Here, you can see the 3 inch thick laser cut flange. Look how smooth the porting is from the flange into the primaries. The American Racing headers also include this scavengers spike, which provides even flow from the primaries down to the collector. Here you can see on the 3 inch stainless steel mid-pipe, this is what makes the direct connect system. It goes from 3 inches then necks down, so work with a stock cat back system or any cat back design will work with the stock mid-pipes. You can also see inside this one here, you can see the inside of the high-flow catalytic converter. That will be 200 cell. It's going to be very, very ultra high-flow, but still keep you emissions legal. American Racing provides everything necessary to install their headers, including clamps, new gaskets, new hardware, O2 extensions, and a bracket for securing the AC line and keep it away from the headers. These American Racing headers are a great way to add horsepower and torque to your 2015 through 2016 Mustang GT. Even though they include a catalytic converter because it's such a high-flow cat, we'll want to custom tune when running these.
