Quick Time Performance Screamer Exhaust Systems
Quick Time Performance Screamer exhaust systems feature dual-mode mufflers with a single inlet to a dual outlet. One outlet is a straight pipe with a valve at the end. When the valve is open, you get the loud and free-flowing exhaust system. Close the valve, and the exhaust gases are diverted though the muffled section to get a quiet, mild-mannered sound. Screamer is the only exhaust system that you can control from the driver's seat—get the power and sound that you desire at the flip of a switch! Order the model designed for your vehicle.

Chevrolet Performance Bowtie Aluminum Cylinder Heads
Chevrolet Performance Bowtie aluminum cylinder heads offer an ideal combination of street drivability and drag-strip performance. These aluminum cylinder heads provide a broad power range with ample low-end torque, along with excellent throttle response, good mid-range torque and enough top-end power to beat your competitors to the finish line. Designed for high performance applications, the Bowtie Street cylinder heads are manufactured to precise machining tolerances, with thick deck surfaces and high-velocity airflow passages. They are available in either rectangular or oval intake port configurations. The rectangular intake ports are larger in volume and have been designed to enhance high-rpm horsepower, which makes them best for vehicles that see frequent drag-strip action. Cylinder heads with oval intake ports are smaller in volume and designed for greater low-rpm torque, therefore they're best for street applications, where lots of bottom end, off-the-line power is desired. Bowtie Street Cylinder Head Technical Notes: * Made from 356-T6 aluminum * Available in rectangular or oval-port designs * Will work on Mark IV and Gen V, VI blocks * 9/16 in. thick decks * As-cast intake and exhaust ports * No heat risers * 1.55 in. valve spring seat diameter * Heli-coiled 7/16 in. screw-in rocker stud holes * Designed for use with 3/8 in. pushrods * Use intake gasket P/N 12366985 and bolt kit P/N 12367959 * Use head gasket P/N 12363414 for bores to 4.370 in. and P/N 12363413 for bores 4.470 in. to 4.540 in.

Pacific Performance Engineering CNC-Ported LLY/LBZ/LMM Cast Iron Cylinder Heads
PPE's CNC-ported LLY/LBZ/LMM cast iron cylinder heads are the ultimate upgrade to your Duramax engine to eliminate any head gasket or cracking concerns. Cast from high-quality alloyed gray iron, the PPE cylinder heads offer elevated fatigue strength, heat, and creep resistance, which prolongs the cylinder head's lifespan significantly. The cylinder heads also share the same heat expansion rate as the stock cast-iron cylinder block—no more blown head gaskets! PPE's CNC-porting process improves airflow, enhancing power, fuel efficiency, and throttle response while reducing engine stress and turbo lag. By smoothing the ports and maintaining wall thickness, these heads provide increased horsepower and torque without sacrificing reliability. Tailored to each specific head, the CNC machining compensates for casting variations, ensuring consistent and optimized airflow dynamics. Whether you have a damaged aluminum cylinder head or a desire for better reliability and longevity on your Duramax engine, cast iron cylinder heads from Pacific Performance Engineering are undoubtedly the best choice. Product features: * Specially alloyed gray cast iron liquid-cooled cylinder head * 5-Axis CNC-ported intake and exhaust ports for smooth, unrestricted airflow * Increased thermal efficiency compared to aluminum heads * Reduced noise and vibration, better ride * Eliminates head gasket scrubbing issue (blown head gasket) * Higher fatigue strength and heat resistance * Premium 21-4N, Stellite-reinforced exhaust valves * Fully nitridated valves, better abrasion resistance * Ready to install—comes with all valvetrain components, rocker arm dowels, and freeze plugs * Requires the use of LBZ/LMM glow plugs on LLY engines (sold separately) Important Notes: The valve seats of the PPE heavy cast iron cylinder heads are installed with an interference that maximizes the durability and lifespan of the cylinder heads. Such interference might not be optimal for extreme-performance applications where a significant amount of heat is created. For those applications, PPE suggests that the exhaust valve seats be replaced with higher interference (+0.006 in. to +0.008 in.) oversized exhaust valve seats (Nominal size 34mm).

HushMat Complete Vehicle Insulation Kits
HushMats complete vehicle insulation kits serve two important functions: reducing thermal transfer into your interior, and reducing the noise level by up to 15 decibels. Your engine, headers, manifold and exhaust generate tremendous heat that transfers to the metal firewall and floor—forcing your A/C system to work harder to maintain a comfortable environment. HushMat auto heat shield is proven to lower this temperature by over 40 percent. At the same time, when you drive on the highway at 65 mph, most vehicles approach 80 to 90 decibels of noise. That's like a vacuum cleaner or garbage disposal running on your passenger seat. These insulation kits use a specially designed sound deadening material to deliver a more peaceful ride. Each kit is packaged specifically for your vehicle to provide 100 percent insulation coverage—no holes in the material and no puzzle pieces to assemble. Treat your firewall, doors, floor, tunnel, rear wheel wells, trunk floor, and roof with these HushMat barriers. Order the complete insulation kit designed for your specific vehicle. Additional details: * Reduces road noise and vibration, low-frequency noise from 0 to 1,000 Hz * Stay warmer in the winter and cooler in the summer; withstands ambient temps from -30 up to +550 degrees F * Lightweight and super flexible mats; less than 1/8 in. thick and 0.47 lbs. per sq. ft. * Adhesion is guaranteed; no alcohol or acetone wash needed; no tools required * Trims easily with standard razor knife or household scissors * Self-adhesive peel-and-stick; no glue required * Outperforms closest competitive brand by over 40 percent * OEM approved; meets or exceeds auto damping specs GMO 149M – General Motors; WSB-M5G58-A1 – Ford; and MS-CD 629 Type C – Chrysler
