Do I need to buy any other parts along with this Akrapovic CLA 45 exhaust?

Yes. This Evolution Line rear section does not include the link pipe that connects it to the factory mid-pipe, so L-ME/SS/3 is mandatory for the system to function. You'll also need a Control Kit for the valve electronics to work with AMG Dynamic Select, so budget for both before ordering.

Which Control Kit do I need for my CLA 45?

It depends on your build date. Pre-facelift CLA 45 and CLA 45 S models use Control Kit P-HF1298, while facelift models use P-HF1528. The kits are not interchangeable, since the valve control electronics changed between the two production runs, so check your build date before ordering.

How much power does this exhaust add to the CLA 45?

Independent dyno testing shows a gain of 6.4 kW (8.7 hp) and 9.1 Nm (6.7 lb-ft) of torque at 6,700 rpm over the factory exhaust. The gain comes from reduced backpressure through the titanium construction and the mandatory link pipe, without any changes to the engine's tuning or fueling.

How much weight does the Akrapovic Evolution Line save over the factory exhaust?

The titanium rear silencer weighs 11.2 kg (24.7 lb) against a heavier factory steel unit, a savings of 9.6 kg (21.2 lb), or 46.2%. That weight comes off the rear axle, which noticeably improves the car's balance and throttle response compared to the stock system.

Does this exhaust fit the Mercedes-AMG CLA 45 S Shooting Brake, or only the coupe/sedan body style?

The Akrapovic Evolution Line for chassis C118 / X118 covers both the CLA 45 and CLA 45 S, and Akrapovic confirms fitment extends to the CLA 45 S Shooting Brake as well. The rear section, link pipe, and Control Kit are shared across body styles, so ordering is identical regardless of which one you drive.

Will adding the optional titanium Downpipe affect emissions compliance on my CLA 45?

Yes. The Downpipe (SS) removes the factory catalytic converter's restriction and is built for closed-course, off-road, or track use only. Akrapovic states it voids ECE type approval, so it is not legal for road use in markets that require emissions certification. Order it only if your vehicle will not need to pass an emissions or noise inspection.

Description

Akrapovic Titanium Evolution Line for C118 / X118 Mercedes-AMG CLA 45

Name: Akrapovic CLA 45 Exhaust | Bulletproof Automotive
Brand: Akrapovic
SKU: S-ME/T/6H
Price: 6115.41 USD
Availability: BackOrder

This Akrapovic CLA 45 exhaust replaces the factory rear section on the Mercedes-AMG CLA 45 and CLA 45 S with a full titanium Evolution Line, built to shed weight and open up the M139’s exhaust note without touching the car’s daily drivability. Akrapovic has built performance exhausts for over fifty years of motorsport, and that engineering carries straight into this system: independent dyno testing shows a gain of 6.4 kW (8.7 hp) and 9.1 Nm (6.7 lb-ft) at 6,700 rpm, paired with a titanium rear silencer that cuts 9.6 kg (21.2 lb) from the factory unit. It’s a system for owners who want their CLA 45 to sound and perform the way its badge promises, not just look the part.

Sound and Valve Control

The Evolution Line integrates directly with the CLA 45’s AMG Dynamic Select drive modes through an Akrapovic Control Kit, letting the exhaust valves open and close in step with the car’s existing drive mode selector rather than a separate aftermarket switch. Because the electronics package changed at the CLA’s facelift, the correct Control Kit depends on your build date, and ordering the wrong one will leave the valve control non-functional even though the pipework itself fits fine.

Features

Full titanium construction for reduced weight and a deeper, more resonant exhaust note
Direct integration with factory AMG Dynamic Select valve control via Control Kit
TIG-welded titanium muffler with a brushed titanium finish that resists discoloration under heat
Slip-fit installation onto the factory mid-pipe using the mandatory Evolution link pipe
Optional titanium Downpipe and Sound Kit available for owners who want maximum weight savings or track-only volume

Specifications

Power gain: +6.4 kW / +8.7 hp (metric) / +8.6 hp (imperial) at 6,700 rpm
Torque gain: +9.1 Nm / +6.7 lb-ft at 6,700 rpm
Weight savings: -9.6 kg / -21.2 lb (-46.2% vs. factory)
System weight: 11.2 kg / 24.7 lb
Installation time: approximately 300 minutes
Material: full titanium

What’s Included

Mercedes-AMG CLA 45 / CLA 45 S: C118 / X118 | M139 2.0L Turbo

Notes

Ordering the wrong Control Kit will not damage the car, but valve control will not function
The optional titanium Downpipe (SS) voids ECE type approval and is intended for closed-course use only
The optional Sound Kit P-HF1296 increases exhaust volume and is best suited to track use
Professional installation is recommended

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
