This is by far the best ad for an exhaust video. I’ve been a magnaflow/Borla guy for years but now that I can actually hear what I’m going to buy I think this is my next setup for my new 2500

[@bullyhenders6755]

the side by side comparisons were the best I've ever seen of any exhaust video heads down.

[@davidgeorge4113]

Best info and hearing ad that I have seen and heard. Hats off to your company. When I get an HD you are the one to get.

[@iliketowatchthis]

I am interested in the headers and legend catback system. With changes of location of the oxygen sensors, does the truck require a tune on the computer to optimize performance and actually run correctly? Have you guys put this truck on a dyno and had tuning done?

[@chrisc5574]

Also interested in this

[@mikejenkins4135]

Nice sound…what are HP AND Torque gains over stock?

[@ReidHenderson]

American truck makers should go back to using the Cubic inch designation on heavy duty trucks with gas engines. 400 cubic inch sounds better than 6.6 and it would seperate it from the Duramax so no confusion would occur.

[@Icutmetal]

😂

[@14albumsuperbia88]

I think if that confuses you, most things will

[@ReidHenderson]

@@14albumsuperbia88 It doesn't confuse me but the Avg person doesn't know the difference between a 6.6 chevrolet gas or 6.6 Duramax. Same with a Ford 7.3 Diesel vs the newer 7.3 Gas.

[@LoneWolfSnowplowing]

@@ReidHenderson by that logic they might think it's Burt Reynolds driving a late 70's Trans Am.

[@Icutmetal]

@@ReidHendersonWhy do you get to be the voice for average people?

[@markalford5406]

What is the Hp and torque gains ?

[@mikepayne2572]

Add a switchable exhaust valve for selecting between loud and quiet and I would buy

[@RJZJR1]

Finely a great addition.

[@Icutmetal]

What’s a finely?

[@Hosshoggbossdogg]

Quite intense for a exhaust video

[@HTSS8]

Do decimal meter inside for all compared.

[@jdwvw]

I want to see the Dyno results.

[@bigbeef8935]

still letting the same amount in, just making more noise

[@jassimahmed5766]

Sounds amazing !! Will this fit the new regular cab 3500 Hd dually ?

[@donaldduck119]

I am debating on same truck.

[@matthewvincent3327]

What do have for a 2013 Chevrolet Avalanche 5.3? I'm looking for Headers, High Flow Cats , and y pipe with no 3rd cat in to a cat back exhaust

[@KTB3007]

G D It that is living proof headers make a sound diff!!!

[@swappedoutZ71]

Crazy it sounds better on stock manifolds 🤔

[@Denali_Rebel]

Why are exhausts such a difficult decision

[@MrTylerg506]

So should I get 1-7/8 long tube headers for my stock 2016 2500HD 6.0 or 1-3/4? I plan on putting true duals also. I’m still debating because I don’t want to loose low end torque but I also want more hp.

[@andrewbrister7200]

Either or, your loss of low end will be so minimal you shouldn’t even notice the difference in pulling or daily driving at all..

[@juanmartinezinc59]

What about having to tune the truck after due to 02 sensors

[@paulsmith-ld8xl]

Sweet

[@samduran5180]

🔥🔥🔥

[@311hitwall]

How do you install the headers on a 6.6l? The site says the headers are not made for emissions.

[@STAINLESSWORKSNET]

Reach out to customer service, they'll run you through it.1-800-878-3635

[@donaldduck119]

Which ones are California legal?

[@ViperMods_216]

All

[@rrlandservice9017]

When is a system for the ram 2500 6.4 going to be available?

[@bigbeef8935]

When they fix the transmissions failing at 32k miles . Still be awhile

[@jeremymagistad5884]

Where is the link to buy this.

[@Icutmetal]

Is your google broken?

[@Icutmetal]

Made in Ohio 👌

[@Back_door_bandit_98]

Honestly I thought they would be louder kinda disappointed.

[@chrisc5574]

Do the headers void any factory warranty?

[@ChilesSupportTV]

Does the 6.6 Duramax turbo diesel sound as good?

[@Icutmetal]

C’mon, man…

[@derricklove1052]

Did the truck run lean with the headers? Waiting till the 6.6 is tunable.

[@zacharybeebe3162]

Pretty sure you have to swap to an after market computer in order to get any tuning since gm encrypted the ecm because I reached out to a few people and they said they don’t offer tuning due to that so I believe you would have to buy an aftermarket computer and buy all the credentials and install them and then you can get into the computer and change from that point on

[@bigbeef8935]

ahh yes someone else who doesn’t understand Fuel injection

[@b_law949]

Do you have exhaust systems that work on the express vans?

[@kkoch666]

Sometimes your better off finding a good shop to just build a custom system.

[@shaneb1501]

6.6 gas or diesel?

[@christopherhamilton4373]

Gas

[@Icutmetal]

You serious, Clark?
