Best Exhaust For Porsche 993
This section breaks down the top contenders for your 993. Each system has its own personality. Some roar, some sing, some purr. Your job is to pick the one that matches your driving style.
Fabspeed Motorsport Exhaust Systems
Fabspeed is a household name among Porsche enthusiasts. Their 993 exhausts are known for aggressive sound and weight savings. You get a deep, raw tone that screams air-cooled heritage.
- Materials: T304 stainless steel or titanium options
- Weight savings: Up to 20 pounds over stock
- Sound: Loud, raspy, with a pronounced crackle on decel
- Emissions: CARB legal versions available
Fabspeed offers both cat-back and header-back systems. The cat-back is easier to install and less intrusive. The header-back is for those who want maximum volume and power. Expect a 10-15 horsepower gain with a tune.
One downside: drone at highway speeds can be noticable. If you daily drive your 993, consider the resonated version. It tames the interior noise without killing the exterior bark.
Bbi Autosport Exhaust
Bbi Autosport focuses on precision engineering. Their 993 exhausts are hand-crafted in the USA. The sound is more refined than Fabspeed, with a melodic howl that builds to a crescendo.
- Materials: T304 stainless steel with mandrel bends
- Weight: Similar to stock but with better flow
- Sound: Smooth, linear, with a clean high-end scream
- Features: Dual-wall tips prevent discoloration
Bbi systems are quieter than Fabspeed at idle. They come alive above 4,000 RPM. This makes them ideal for street use and occasional track days. The build quality is exceptional, with perfect welds and fitment.
Installation is straightforward. All hardware is included. You can do it in your driveway with basic tools. Expect no check engine lights or fitment issues.
Gemballa Exhaust Systems
Gemballa is a legendary Porsche tuner. Their 993 exhausts are rare but highly sought after. The sound is distinctive—a deep, guttural growl with a European flair.
- Materials: Stainless steel with ceramic coating options
- Sound: Deep, throaty, with minimal drone
- Weight: Moderate weight savings
- Availability: Limited production runs
Gemballa systems are not for everyone. They are expensive and hard to find. But if you want something unique, this is it. The sound is more refined than aftermarket brands, with a touch of class.
Be prepared to search for used units or wait for a new batch. Fitment is generally good, but some owners report needing minor adjustments. Worth it for the exclusivity.
M&K Exhaust
M&K is known for high-quality, affordable exhausts. Their 993 systems offer a balanced sound without breaking the bank. You get a sporty tone that’s livable for daily driving.
- Materials: T304 stainless steel
- Sound: Medium loudness, with a clean note
- Weight: Similar to stock
- Price: One of the most affordable options
M&K exhausts are a great entry point. They are not as loud as Fabspeed, but they still enhance the flat-six character. The build quality is solid, though welds are not as pretty as Bbi.
Drone is minimal, making them good for long trips. Installation is simple, and the price leaves room for other upgrades. A smart choice for budget-conscious owners.
Rennline Exhaust
Rennline focuses on performance and lightweight design. Their 993 exhausts use titanium for serious weight reduction. The sound is exotic, with a sharp, metallic edge.
- Materials: Titanium or stainless steel
- Weight: Up to 30 pounds lighter than stock
- Sound: Aggressive, with a distinctive titanium crackle
- Features: Adjustable tips for perfect fitment
Rennline systems are for track enthusiasts. They are loud and raw. The titanium version changes color over time, giving a race-car aesthetic. Expect a 5-10 horsepower gain with proper tuning.
Drone is present, especially in the titanium version. Not ideal for daily driving. But if you want to shed weight and sound like a GT3, this is your pick.
Key Factors To Consider When Choosing
Not all exhausts are created equal. Your choice depends on how you use your 993. Let’s break down the most important factors.
Sound Preference
Sound is subjective. Some love a loud, aggressive bark. Others prefer a refined howl. Listen to clips online or attend a local Porsche meet. Hearing systems in person is the best way to decide.
- Loud: Fabspeed, Rennline
- Refined: Bbi, Gemballa
- Balanced: M&K
Remember that sound changes with temperature and load. Cold starts are louder. High RPMs bring out the best notes. Consider your neighbors and daily commute.
Weight Reduction
Every pound counts on a 993. A lighter exhaust improves handling and acceleration. Titanium systems save the most weight, but they cost more. Stainless steel is heavier but more durable.
- Titanium: Rennline, some Fabspeed options
- Stainless steel: Bbi, M&K, Gemballa
If you track your car, go titanium. For street use, stainless steel is fine. The weight savings are noticable but not transformative.
Emissions Compliance
Some areas require CARB approval. Check local laws before buying. Fabspeed offers CARB-legal versions. Other brands may not. Running a non-compliant system can lead to fines or failed inspections.
- CARB legal: Fabspeed (select models)
- Not CARB legal: Most aftermarket systems
If you live in California or similar states, prioritize compliance. It’s not worth the headache. You can still get great sound with a legal system.
Drone And Cabin Noise
Drone is a low-frequency hum at cruising speeds. It can be exhausting on long drives. Researched systems like Bbi and M&K minimize drone. Fabspeed and Rennline are louder inside.
- Low drone: Bbi, M&K, Gemballa
- Moderate drone: Fabspeed (resonated)
- High drone: Rennline, Fabspeed (non-resonated)
Test drive if possible. Or ask owners on forums. Drone tolerance varies. Some people love it, others hate it.
Installation Guide
Installing a new exhaust is a weekend project. You need basic tools and patience. Here’s a step-by-step guide.
Tools You Need
- Jack and jack stands
- Socket set (10mm, 13mm, 17mm)
- Penetrating oil
- Rubber mallet
- Safety glasses and gloves
Step-By-Step Process
- Jack up the rear of the car. Secure it on jack stands.
- Spray penetrating oil on all exhaust bolts. Let it sit for 10 minutes.
- Remove the stock exhaust. Start with the muffler bolts, then the mid-pipe.
- Carefully lower the stock system. It’s heavy, so get help.
- Install the new exhaust. Use new gaskets if provided.
- Tighten bolts to spec. Do not overtighten.
- Check for leaks. Start the engine and listen.
- Lower the car and take a test drive.
Most systems fit without modification. If something doesn’t align, loosen all bolts and adjust. Tighten gradually. Expect some heat cycling before the sound settles.
Maintenance Tips
Exhausts need care. Here’s how to keep yours looking and sounding great.
- Clean tips regularly with metal polish.
- Check bolts for tightness after 500 miles.
- Inspect for cracks or leaks annually.
- Avoid pressure washers near welds.
Stainless steel systems last decades. Titanium can discolor, which is normal. Ceramic coatings may chip over time. Touch up with high-temp paint.
