Understanding Your Akrapovic System

Have you bought the right system for your goals? This matters because installation complexity varies dramatically.

Slip-On Line: The Entry Point

Akrapovič’s Slip-On Line represents the first step in exhaust system tuning . It replaces just the rear section (muffler) while retaining your vehicle’s stock header pipes and emissions systems .

What to expect:

Simpler installation—often bolt-on with no modifications
No ECU remapping required—plug-and-play
ECE type-approved—road legal when installed as intended
Weight savings—35.2% lighter than stock on some applications
Modular design—can be upgraded to Evolution Line later

The Porsche 991.2 GT3 RS Slip-On Line is “designed to be easily installed onto the Porsche GT3 RS’s original system” . Similarly, the KTM 790 Duke slip-on offers “plug & play installation with no ECU flashing required” .

Evolution Line: Maximum Performance

The Evolution Line caters to enthusiasts seeking maximum performance enhancements and an even deeper, richer sound . These systems extend the Slip-On Line by including additional high-performance components such as link pipe sets or header sets .

What to expect:

More complex installation—often multiple components
ECU remapping mandatory—”given the extensive nature of these upgrades, an ECU remap is almost always necessary”
ECE approval may be affected—upgrading may invalidate type approval
Maximum weight savings—Audi RS Q8 Evolution weighs 44.1% less than stock
Greater power gains—documented increases across the range

The Audi RS Q8 Evolution system features “high-grade titanium tubes and a muffler, attached to the car’s stock downpipes with a high-quality stainless-steel link pipe” .

Mandatory and Optional Parts

Here’s where many first-timers get caught out. Akrapovic systems often require additional components :

Mandatory parts vary by vehicle but commonly include:

Tailpipes—unless integrated into the system
Diffusers—for specific applications
Mounting equipment—brackets and hardware

The Porsche system warns: “The mandatory tail pipe set needs to be ordered separately” . Always check with your UK dealer before purchasing .

Optional parts enhance functionality:

Downpipes—improve exhaust flow but may affect road legality
Sound Kits—Bluetooth or smartphone control of exhaust valves
Link pipe sets—upgrade Slip-On to Evolution specification
Carbon fibre diffusers—aesthetic enhancement

This chart compares Slip-On and Evolution systems across key installation factors.

Before You Start: Preparation

Tools You’ll Need

Based on installation guides and forum experience, gather these :

Tool	Purpose
Basic toolkit	Wrenches, sockets, screwdrivers
Torque wrench	Critical for correct bolt tightness
Axle stands or lift	Vehicle must be stable and secure
Penetrating oil	For stubborn exhaust fasteners
Spring puller	If your system uses exhaust springs
Safety gloves	Protect hands from sharp edges and heat
Service manual	Vehicle-specific torque values

The Night Before

One forum member’s hard-earned advice: spray all exhaust mounting bolts and header nuts with penetrating oil the night before . UK road salt loves seizing exhaust fasteners. Give it time to work.

Vehicle Preparation

Park on level ground—safety first
Ensure vehicle is stable—use axle stands, never just a jack
Disconnect the battery—prevents electrical hazards
Allow exhaust to cool completely—if vehicle has been running

Step 1: Remove the Stock Exhaust

Getting Access

Every vehicle is different, but expect to remove or move components blocking access. On the BMW S1000R, the installer had to move :

Right foot pegs
Fairing panels
Radiators
Radiator bracket
Coolant overflow

For your sportscar, you may need to remove undertrays, heat shields, or rear valance panels. Take photos as you go—they’re invaluable for reassembly.

Disconnect Sensors

Locate and disconnect lambda (oxygen) sensors
Carefully free wiring from clips and holders
Protect sensor tips—they’re fragile and expensive

Remove the Stock System

Support the exhaust—it’s heavier than you expect
Remove mounting bolts and hangers
Separate connections—slip joints, clamps, or flanges
Lower the system carefully—avoid damaging sensors or bodywork

One forum member described the challenge: “Everything is VERY tight, it takes patience and care to take the exhaust out without damaging the radiators” .

“After quite a bit of fighting everything is out of the way” — jucam, S1000R owner

Step 2: Prepare the Akrapovic Components

Unpack and Inspect

Lay out all components in installation order
Verify everything is present—check against the parts list
Inspect for damage—though rare, better to catch it now
Read the instructions—Akrapovic provides specific guidance

Check Fitment (Critical!)

Here’s where one forum member hit trouble. Their HP4 Akrapovic system had header pipes 2mm too large for their engine :

“The header diameter at the engine end is 2mm too big versus the stock. I had to head down to a local machine shop and have the first lip lathed down a couple millimeters”

This is unusual for a system designed for your specific vehicle, but highlights why buying the correct application matters. Always verify compatibility before starting .

Prepare Fasteners

Some Akrapovic systems use springs to connect sections. Have your spring puller ready—these require patience and wear gloves because they slip.

Step 3: Install the New System

The Golden Rule: Loose Fit First

“It’s crucial to loosely fit all parts first, allowing for adjustments before final tightening. This ensures optimal alignment and fitment.”

This cannot be overstated. If you tighten everything as you go, you’ll end up with misaligned pipes and strained mounts.

Correct sequence:

Start at the engine—install header pipes or front sections
Work rearward—add mid-pipes, then muffler
All bolts finger-tight—nothing fully tightened yet
Check alignment—ensure nothing contacts bodywork or suspension
Adjust as needed—slide joints, rotate muffler for perfect tailpipe positioning

One installer’s hard-learned lesson: “Don’t do what i did there and because the pipe won’t fit… First assemble the first bit of pipe, put the sleeve, the plate and the springs AND THEN connect it to the engine” .

Connect Sensors and Valves

If your system includes:

Lambda sensors—install into provided bosses
Exhaust valve motor—may need cable adjustment
Sound Kit actuators—if applicable

The S1000R installer noted: “The length and the bend of the fitting of the cable where different so i just reused the hp4 cables” .

Tighten to Spec

Once alignment is perfect:

Torque all fasteners to manufacturer specifications
Follow sequence—some components need specific order
Double-check—”make sure all the bolts are sufficiently tightened”

“WARNING: check vehicle manufacturer manual for tightening torques (for dismounted stock parts)!”

Step 4: Final Checks and First Start

Inspection

Reconnect battery
Check clearance—”In case the exhaust system touches the cowling or other parts repeat the adjustment”
Verify all tools removed—nothing left in engine bay
Double-check fasteners—one last look

The First Start

This moment always causes panic, but it’s completely normal:

“IT IS NORMAL IF WHITE SMOKE COMES OUT OF THE MUFFLER ON FIRST OPERATION. DO NOT STAND BEHIND THE MUFFLER ON FIRST OPERATION.”

The white smoke is:

Manufacturing oils burning off
Packing material settling
Protective coatings curing

It stops after a few minutes. Just don’t stand behind it while it happens.

Check for Leaks

With engine idling:

Listen for “putting” sounds at connections
Feel for exhaust pulses at joints (carefully—it’s hot)
Rev gently and listen for changes

The 30-Minute Retorque

After your first drive (or 30 minutes of running), allow the system to cool, then retorque all exhaust fasteners. Heat cycling settles everything.

The Tuning Question: Do You Need an ECU Remap?

This is critical and varies by system.

Slip-On Systems

Generally, no ECU remapping required . The KTM slip-on explicitly states “no ECU flashing required” . These systems work with stock emissions components and don’t dramatically alter flow.

Evolution and Full Systems

“Given the extensive nature of these upgrades, an ECU remap is almost always necessary to ensure the vehicle operates optimally with the new exhaust configuration.”

The Ferrari 488 system warns: “When installing Akrapovič optional link pipe set with or without catalytic converters, remapping the ECU is mandatory” .

Downpipes and De-Cat Systems

For downpipes with sports cats or de-cat pipes:

“When installing Akrapovič aftermarket optional down pipes with sports catalytic converters or without catalytic converters, which are developed for use on closed tracks only, remapping the ECU is mandatory.”

“The use of de-cats, sports cats are for off road/motorsport use only. Using these parts would inhibit your vehicle from passing a MOT test.”

The Sound Kit Consideration

The optional Akrapovič Sound Kit enables manual exhaust valve control . But there’s a catch:

“If the Akrapovič Sound Kit is fitted, the Evolution Line (Titanium) ECE type-approval certificate is not valid.”

Road Legality: What UK Buyers Must Know

EC/ECE Type Approval

Many Akrapovic systems carry approval . The Porsche system “meets ECE specifications” . The Ferrari system is “ECE type-approved” .

When Approval Is Lost

Upgrading or adding options can invalidate approval:

“If the system is upgraded with link pipe or evolution sets, the ECE type approval is not valid anymore.”

“With the use of the optional Akrapovič Sound Kit, the ECE type approval is no longer valid.”

Your Responsibility

“Only EC type-approved components are legal and fit for road use.”

MOT: Approved systems should pass noise testing
Insurance: Any exhaust modification must be declared

Professional Installation: The Safe Option

Real Owner Experiences

The 7-Hour Struggle

Forum member jucam fitted an HP4 Akrapovic system to their S1000R :

“After about 7 hours of fighting i got her done. As a summary, everybody can do it as long as you have patience and you do it carefully. It get very infuriating at time with very tight areas and weird locations… Totally worth it!!”

Their verdict on the transformation: “I may have lost a little bit down low but there is a definitive improvement up top” .

The Weight Revelation

Another owner noted: “The new system probably weigh a third of the old one” .
