Caliber Catless Downpipe

The cp-e™ exhaust system for the Dodge Caliber SRT-4 comes in two sections: The QKspl™ Caliber Catless Downpipe and the Austenite™ Cat Back Exhaust. We have designed the cp-e™ QKspl™ Downpipe with thick laser cut flanges to bolt directly to your stock components or to the cp-e™ catback exhaust. This 3.5″ SS pipe is essentially a test pipe on steroids. It replaces the second catalytic converter on the vehicle, and runs from the downpipe back to the catback section. The cp-e™ QKspl™ Downpipe is available as a straight pipe with the option to add a resonator and/or a high flow cat. For the greatest performance and sound increase, choose both the QKspl™ Caliber Catless Downpipe and the Austenite™ Cat Back!

cp-e™ does not use mild “junk” steel or even cut and welded intermediate bends on this pipe. Our exhaust systems are crafted from premium “bright annealed” 304 stainless steel and is mandrel bent to provide a less turbulent exhaust flow. The flanges are 3/8″ thick, and laser cut 304 stainless steel for high strength and durability. All critical portions of the pipe areTIG welded. TIG welds are usually avoided in this industry because they require more time and skill than a MIG weld, despite the fact that TIG welds are better suited for thin metals, are better looking, and create a more durable bond. We held nothing back with this product.


While this may not trip a Check Engine Light, we cannot guarantee that all of the codes will be in the “ready” state.

Caliber Catless Downpipe Highlights

Caliber Catless Downpipe

Full 3″ Design

Our Caliber SRT-4 Catless Downpipe was designed with maximum flow and the quickest spool times in mind. To accomplish this, we went with a full 3″ design directly off of the turbos. This promotes quick spool while maintaining the needed back pressure.

F-150 EcoBoost DownpipeHigh flow catalytic converter

Optional High Flow Cat

The cp-e™ Caliber SRT-4 Catless Downpipe is available with or without a high flow catalytic converter. Maximum gains can be found without a cat, but the catted version is incredibly high flowing and sees extremely low parasitic loss from the catalytic converter.

“Factory Fit and Finish

Factory Fit & Finish

This QKspl™ downpipe system is manufactured for a perfect fit and finish. This downpipe will work perfectly with your stock cat back for a stealth install or along with our Austenite™ exhaust system for the most pure sound. Thanks to a CNC cut flange, the downpipes will fit the factory cat-back perfectly.

    Recently purchased and installed the CP-E downpipe for my 09 Caliber SRT4.
    Very impressed with communication and prompt delivery, unlike other companies that I have dealt with (modern performance). The sound is aggressive but not ricey. I could instantly feel the power and responsiveness! Great product. Great company! Will purchase the cat back exhaust in the near future.
    Thanks again guys! Keep up the good work!
