Akrapovic Slip-On Line (Titanium) - Ferrari 488 GTB/488 Spider 2016 - 2019 SKU: MTP-FE488H

This is a high-end titanium cat-back rear exhaust upgrade developed specifically for the Ferrari 488 GTB and 488 Spider. 

It is especially interesting because the 488’s 3.9L twin-turbo flat-plane V8 already has enormous performance, so Akrapovič focuses on reducing mass, improving exhaust flow and sharpening the soundtrack rather than simply making the exhaust louder.

🔧 The engineering

Specification	MTP-FE488H
Vehicle	Ferrari 488 GTB / 488 Spider
Years	2016 - 2019
Construction	Titanium
Tailpipe finish	Titanium + carbon-fibre outer sleeve
System	Slip-On
Weight reduction	3.8 kg / 35.2%
Power gain	+7.7 - 7.8 hp @ 6,800 rpm
Torque gain	+6.3 Nm @ 5,200 rpm
Homologation	ECE Type Approval

Akrapovič’s published figures show the system dropping from about 10.8 kg to 7.0 kg, while producing approximately 666 hp vs. 660 hp in the cited test configuration. 

🧠 Why titanium matters

The clever part isn’t simply that titanium is lighter.

Akrapovič uses special lightweight titanium alloys and components cast in its own foundry. The system also employs larger-diameter tubing and a revised internal configuration to improve gas flow and reduce backpressure. 

For a mid-engine Ferrari, removing 3.8 kg from the rear exhaust assembly is valuable because it reduces mass concentrated toward the back of the car.

Think of it as:

lighter exhaust → lower rear mass → slightly less inertia → sharper response

The horsepower increase is relatively modest, but the combination of weight reduction + flow + sound is what makes the system compelling.

🔥 The Ferrari-specific magic

The 488’s V8 is flat-plane, so its exhaust character is fundamentally different from a cross-plane V8. Akrapovič deliberately tuned the system around that character rather than trying to make it sound like a generic American V8.

The optional Akrapovič Sound Kit can control the exhaust sound settings. 

And the visual treatment is extremely appropriate for the 488:

Titanium exhaust → sculpted tubing → carbon-fibre tailpipe sleeves → Ferrari’s exposed rear architecture.

⚠️ Important distinction: Slip-On vs. full system

The MTP-FE488H itself is the Slip-On system. Akrapovič also offers optional stainless-steel link pipes, with or without catalytic converters. 

If those optional link pipes are installed, ECU remapping is required, according to the product documentation. 

So I’d view the configurations like this:

MTP-FE488H alone
→ OEM-oriented installation
→ weight reduction
→ modest performance improvement
→ enhanced Ferrari V8 character
→ ECE-approved configuration

MTP-FE488H + optional link pipes
→ substantially more aggressive exhaust-flow configuration
→ stronger sound transformation
→ requires appropriate ECU calibration when specified by Akrapovič

🏁 The verdict

This is not an exhaust designed merely to scream louder.

It is a quintessential Akrapovič product because its philosophy is:

Mass reduction + gas-flow optimization + acoustic engineering + exotic materials + OEM-level integration.

For a Ferrari 488, I’d rate its priorities:

Weight reduction: ⭐⭐⭐⭐⭐
Engineering sophistication: ⭐⭐⭐⭐⭐
Sound quality: ⭐⭐⭐⭐⭐
Power gain: ⭐⭐⭐⭐
Visual presentation: ⭐⭐⭐⭐⭐
Track/spirited-drive appeal: ⭐⭐⭐⭐⭐

The 3.8 kg reduction is actually one of the most impressive numbers here. The +7.8 hp headline is nice, but the real attraction is that Akrapovič manages to make an already exceptional 488 lighter, freer-flowing and more sonically dramatic without turning it into a crude loud-exhaust build.

Dodson Forged Basket / Output B ( 1 3 5 R ) for Nissan GT-R DMS-3213

The Dodson Motorsport DMS-3213 is a forged-steel B clutch basket for the Nissan GT-R R35’s GR6 dual-clutch transmission (DCT). It handles the clutch/output side associated with 1st, 3rd, 5th and Reverse gears. 

🧠 What is the “basket”?

Think of the GR6 clutch basket as the structural drum that contains and supports the clutch pack.

During high torque operation, the clutch assembly is subjected to enormous:

• clamping forces
• rotational loads
• heat
• torsional shock
• repeated rapid gear changes

A conventional OEM basket can experience distortion/flexing under very high load. Dodson’s forged basket is designed to maintain its geometry better under those conditions. 

⚙️ Why Output B matters

The GR6 essentially divides its dual-clutch architecture between two gear groups:

Basket	Gear group
Output A	2nd / 4th / 6th
Output B - DMS-3213	1st / 3rd / 5th / Reverse

Dodson lists DMS-3212 as the A-basket and DMS-3213 as the B-basket. 

So DMS-3213 isn’t a complete clutch upgrade by itself—it’s one structural component of the GR6 clutch system.

🔩 The clever engineering

1. Forged/strong steel construction
The stronger basket is intended to resist deformation when torque and clutch loading increase. Dodson specifically describes the B-basket as being designed for high-horsepower, high-plate-count applications. 

2. Induction-hardened spline
The spline receives surface hardening to improve wear resistance. That’s important because the spline is repeatedly exposed to torque transmission and cyclic loading. 

3. Integrated/supporting bearing arrangement
The Dodson version incorporates a bearing at the basket base to provide additional load support and durability. 

4. Better dimensional stability
This is arguably the biggest benefit. If the basket distorts under load, clutch-pack geometry can change. Keeping the basket more rigid helps the clutch assembly maintain more consistent engagement.

🔥 Why an R35 owner would care

The VR38DETT + GR6 DCT combination is capable of producing very large torque. Once an R35 moves substantially beyond stock power, the transmission isn’t simply dealing with engine torque—it is dealing with rapid clutch engagement and torque multiplication through the drivetrain.

That’s why Dodson’s transmission philosophy is essentially:

More torque → more clutch force → more structural load → stronger basket required.

The DMS-3213 is therefore a transmission-strengthening component, rather than a horsepower-producing modification.

⚠️ Important installation detail

Dodson specifies that the basket comes with a 65.35 mm bearing inner diameter, and the OEM clutch centre needs machining to 65.35 mm +0.00/−0.03 mm to accept that bearing. 

So this isn’t necessarily a simple “remove OEM → bolt in Dodson” component. Proper transmission assembly and dimensional verification are important.

🏁 Summary

Think of the DMS-3213 as the reinforced skeleton of one half of the R35 GR6’s clutch system.

OEM basket:
Torque → structural deformation becomes a concern at extreme loads

Dodson DMS-3213:
Torque → stronger forged structure → reduced distortion → better clutch-pack support → greater transmission durability

And the really interesting part is that B handles 1/3/5/R while A handles 2/4/6, so a serious GR6 build may address both sides rather than treating the transmission as a single clutch.

ORC RACING CONCEPT ORC-309-RC SINGLE FOR HONDA CIVIC ORC-309D-HD0101-RC

 

ORC RACING CONCEPT ORC-309-RC SINGLE FOR HONDA CIVIC ORC-309D-HD0101-RC

The ORC Racing Concept ORC-309-RC Single — ORC-309D-HD0101-RC is a very serious single-plate racing clutch from Ogura Racing Clutch, aimed at Honda B-series cars such as the Civic EK4/EK9 and Integra DC2. 

🏁 What makes the ORC 309-RC special?

Think of it as a clutch designed around one objective: remove rotational inertia so the B-series engine responds much faster.

Feature	ORC-309-RC
Architecture	Single plate
Clutch disc	Metal racing disc
Pressure plate	STD pressure type
Damper	Yes
Operation	Push type
Flywheel	Ultra-light chromoly
Rated application	Around 300 PS / 340 Nm
Intended use	Circuit / aggressive driving
Compatible engines	B16A/B16B/B18C
Compatibility	EK4, EK9, DC2, EG6 and others depending on configuration

The particularly important figure is the 60–70% reduction in clutch-system weight versus OEM, according to ORC product information. 

⚙️ Why the lightweight flywheel matters

A normal flywheel stores considerable rotational energy.

The ORC attacks that inertia:

OEM system

Engine → heavy flywheel → clutch → gearbox

ORC 309-RC

Engine → ultra-light flywheel → lightweight clutch → gearbox

The result is substantially less rotational inertia for the engine to accelerate.

That means:

Throttle input → RPM rises faster → shift → RPM falls faster → next gear engages

This is especially interesting on a high-revving B16B/B18C, where rapid RPM changes are part of the engine’s character.

🔥 The clever part: it isn’t completely undamped

The 309D-HD0101-RC uses a damped clutch disc, unlike some extremely aggressive solid racing configurations. That gives it a better compromise between directness and drivability. 

ORC specifically describes the Racing Concept range as being developed for demanding circuit applications, with the lightweight flywheel engineered using FEM analysis. 

🧠 But there’s a trade-off

This is not simply “better than OEM.”

Because so much rotating mass is removed, the engine has less inertia to smooth its own rotation. ORC warns that idle stability can be affected. 

So you gain:

• ⚡ Much sharper throttle response
• ⚡ Faster RPM rise/fall
• ⚡ Faster-feeling gear changes
• ⚡ Less rotational inertia
• ⚡ Stronger racing character

But potentially sacrifice:

• More forgiving clutch engagement
• Idle smoothness
• Some low-speed refinement
• OEM-like refinement in traffic

One important detail: the kit requires the genuine pilot bearing, while the sleeve/release bearings are supplied with the kit; OEM flywheel mounting bolts are also specified. 

Bottom line: the ORC 309-RC isn’t primarily a “maximum horsepower” clutch. Its real weapon is low rotational inertia + very direct engagement + rapid engine response. 

That’s why it makes so much sense behind a screaming B16B/B18C in a lightweight Honda.
