MaxSpeed Porsche Parts: A Complete Guide to Performance Upgrades

When upgrading a Porsche, enthusiasts often turn to MaxSpeed for high-performance parts designed to boost power, improve handling, and enhance the driving experience. MaxSpeed offers a range of components for various Porsche models, including the 911, Cayman, Boxster, and Macan. This guide covers the key categories of MaxSpeed parts, helping you make informed decisions for your specific needs.

MaxSpeed Exhaust Systems

MaxSpeed exhausts are popular for their weight reduction and sound improvement. They offer cat-back and axle-back systems for most modern Porsches.

Cat-Back Exhausts

A cat-back system replaces everything from the catalytic converters back. MaxSpeed cat-backs use T304 stainless steel and mandrel bends for smooth flow. They typically reduce weight by 15-25 pounds compared to stock. The sound is deeper and more aggressive, especially under acceleration, without being overly loud at cruising speeds. For the 991.2 911, MaxSpeed’s cat-back adds about 10-15 horsepower and a similar torque gain.

Axle-Back Exhausts

Axle-backs replace only the mufflers and tips. They are easier to install and cheaper than full cat-backs. MaxSpeed axle-backs retain the stock exhaust valves on compatible models, so you can control noise via the Sport button. Sound level is moderate — louder than stock but not as loud as a cat-back. Great for those wanting a subtle upgrade without major changes.

MaxSpeed Cold Air Intakes

Cold air intakes from MaxSpeed replace the restrictive factory airbox with a high-flow filter and housing. They are designed to reduce intake restrictions and lower intake air temperatures.

Design and Materials

MaxSpeed intakes use a heat shield to block engine heat and a dry or oiled cotton filter. The intake tube is often carbon fiber or aluminum. Carbon fiber offers better heat rejection and a premium look, while aluminum is more affordable. For the 718 Cayman, MaxSpeed’s intake provides around 8-12 horsepower and a noticeable induction sound.

Installation and Maintenance

Installation is straightforward and takes about an hour with basic tools. The filter is reusable and needs cleaning every 20,000-30,000 miles. Avoid over-oiling if using an oiled filter to prevent MAF sensor contamination. MaxSpeed includes detailed instructions and all necessary hardware.

MaxSpeed Engine Tuning

Beyond bolt-on parts, MaxSpeed offers ECU tuning for significant power gains. Their tunes are custom-developed for Porsche engines, focusing on reliability.

Stage 1 vs Stage 2

Stage 1 tuning is for stock vehicles, increasing boost and adjusting fuel and timing. For a 991.1 911 Carrera S, Stage 1 adds about 60 horsepower and 50 lb-ft torque. Stage 2 requires a downpipe and larger intercooler, adding another 20-30 horsepower. MaxSpeed tunes are switchable, allowing you to revert to stock for dealer visits.

Compatibility

MaxSpeed tuning works with most 2013+ Porsche models. They offer remote flashing via OBD-II port, so no need to remove the ECU. The tune includes optimized throttle response, removed speed limiter, and raised rev limit. Ensure your car has no underlying issues before tuning.

MaxSpeed Suspension Components

Handling upgrades from MaxSpeed include lowering springs, coilovers, and sway bars.

Lowering Springs

MaxSpeed springs lower the Porsche by 0.8-1.2 inches, reducing the center of gravity and improving cornering. They are matched to factory dampers for a comfortable ride. Spring rates are selected to maintain daily drivability. For the 997 911, MaxSpeed springs provide a 20% reduction in body roll.

Coilover Kits

For adjustable ride height and damping, MaxSpeed coilovers offer full customization. Their kits use monotube shocks and progressive springs. Height adjustment is independent of damping. Recommended for track-focused drivers. The dampers are valved for a balance of comfort and performance. Installation requires spring compressors and alignment after.

Sway Bars

MaxSpeed sway bars reduce body roll without harshness. They are hollow or solid and have multiple adjustment holes. A rear sway bar on a Cayman sharpens turn-in and reduces understeer. Installation is moderate difficulty; bars come with polyurethane bushings and brackets.

Practical Considerations

When choosing MaxSpeed parts, consider your primary goal: sound, power, or handling. For sound, an exhaust is best. For power, start with an intake and tune. For handling, springs or coilovers.

Warranty and Reliability

MaxSpeed parts come with a limited warranty. They are designed to be direct replacements, so no permanent modifications are needed. Tuning may void factory engine warranty, but MaxSpeed offers a warranty on their tune and hardware. Keep your car serviced regularly.

Installation

Most parts can be DIY with basic tools, but tuning and suspension alignment should be done by a professional. MaxSpeed provides support via phone and email.

Final Recommendation

For a well-rounded upgrade, begin with MaxSpeed’s cat-back exhaust and cold air intake. This combination adds noticeable power and sound without compromise. If you track your car, add the Stage 1 tune and coilovers. For daily driving, the lowering springs and axle-back exhaust give an enhanced experience without sacrificing comfort. Always verify compatibility with your specific model year before purchasing.
