Getting you exactly what you want and making sure you get what you need at the same time! \u003c\/p\u003e\n\u003cp\u003eWhat is an axle-back exhaust? An axle back style exhaust is exactly what it sounds like. It is a system that goes in from the axle of the vehicle back. From muffler or resonator deletes to just an add-on that gets a different style of exhaust tip coming out of the rear end. This means that while axleback may sound specific it really has more than a few different options of what it actually does.\u003c\/p\u003e\n\u003cp\u003eCornerstone is always bringing new models to the table.

Now, this would install right after the outlet of the catalytic converter and then follow the exhaust until the exhaust tips or like some a dump under the vehicle. Cornerstone Performance Solutions know that while this may seem like a simple choice you need to know what does a cat-back system do for you and what exactly can you expect from it?\u003c\/p\u003e\n\u003cp\u003eThe Cat back exhaust is a great option for those who want a full style exhaust but want to leave factory manifolds or headers in place. This is because this attaches to the CAT and leaves most factory warranties in place. With a Cat-back style system, you also will see an increase of roughly 2-5% power on average with the correct tuning. Although tuning is not needed for a cat-back exhaust we do recommend having a tune done that can optimize the new system and truly get you back that lost power due to restriction.\u003c\/p\u003e\n\u003cp\u003eCornerstone Performance Solutions makes a few different Cat back exhaust systems right now like for the F-150 EcoBoost and the 4.3L\/5.3L 1500 series Chevrolet and GMC trucks.

If you're trying to make big power and run that number at the dragstrip or have a fun street car then look no further! We took our R&D to the literal drawing board and looked to maximize every aspect of the Mopar platform. A true bolt on twin turbo kit for the Hellcat, Scatpack market WITHOUT running it through the supercharger. We developed a 100% billet intake manifold with a built-in air/water intercooler in it that will come STANDARD with all of the kits. We started the kit by developing a billet stainless flange to mate/seal to the factory manifolds(we have made 1400+whp through them) because doing headers on these cars is not fun as you may know. The hotside is made out of 2.5" 304 Stainless that will come ceramic coated. Exhaust will connect right to the factory Cat-back or any aftermarket exhaust. Cold side piping is also made out of 2.5" 304 stainless that transitions to a 4" pipe to "fill" the engine bay all of the way to the throttle body.
Example- The stock hellcat supercharger makes around 630-640whp at 12PSI of boost. On this twin turbo setup we made 915whp on 10PSI. Way less restriction, lower IAT's and reduced strain on the drivetrain. At 17PSI we made 1162WHP & 1073 Ft-Lbs.
Features & Benefits of the Twin Turbo Kit from Cornerstone Performance
1800+WHP Capable depending on turbo size

No more battling intake heat issues
Retains all factory sensors
Retains factory cooling system
100% Designed, Fabricated & Finished in the U.S.A.
Kit includes all hardware
What is included in the Twin Turbo Kit fromCornerstone Performance?
