Pacemaker King Brown Single 2 1/2" Exhaust with Headers Kit - Toyota Landcruiser 100/105 Series 4.2L Non-Turbo Diesel - KB12020-HXMX

Breathe new life into your 1HZ engine with this complete King Brown Exhaust & Headers Kit. Specifically engineered for the Toyota Landcruiser 100 and 105 Series equipped with the workhorse 4.2L 6-Cylinder Non-Turbo Diesel (1HZ) engine, this comprehensive Engine Back system replaces the restrictive factory exhaust manifold and underbody piping. By incorporating high-flowing Pacemaker extractors (headers) and a mandrel-bent Single 2 1/2" (2.5 inch) exhaust, it drastically improves engine breathing and exhaust gas scavenging, which is crucial for maximizing the performance of naturally aspirated diesels. Constructed with top-grade 409 stainless steel, this exhaust system is exceptionally tough, durable, and built to handle Australia's harshest off-road environments. Proudly Australian Made for Australian Conditions, it optimises torque, improves throttle response, and delivers a robust, deep exhaust note. Get the elite performance and reliability you deserve with this Brand New King Brown Exhaust System by Pacemaker. Note: Please confirm your vehicle is a Toyota Landcruiser 100 or 105 Series with the naturally aspirated 4.2L Non-Turbo Diesel (1HZ) engine (built 1998 to 2008) before ordering.

Features:

Engineered for maximum unrestrictive flow right from the engine block, ensuring heavy-duty chassis clearance and rugged outback reliability.

  • Material: Tough 409 grade stainless steel construction for excellent corrosion resistance and extreme longevity.
  • Manufacturing: 100% Australian Made for harsh, demanding Australian conditions.
  • Performance: Mandrel-bent piping combined with tuned-length headers significantly improves exhaust gas scavenging, resulting in better low-down torque and overall engine efficiency for the 1HZ engine.

Super soft
Size: Small, Color: Light Blue/White, Size: Small, Color: Light Blue/White
Perfect fit! Bought as part of a set for a bachelorette trip and they are so comfy. Look exactly like the listing photos. Wore them through a Pilates class and a day of errands with no issues. Love the baby blue color with white contrast binding. Perfect stretch, fabric squat proof (thick enough nothing shows when you bend) and very durable.

Soft, fit, and love the color
Size: XX-Large, Color: Slate Grey/White
I love how soft these are and the grayish-violet color. They seem well made and wash well- especially for the price. You can’t see through them. They are mid weight so they keep you warm enough for air conditioning and Florida cold. Probably not snow worthy or wind strength though. They are true to size if you want them to fit but not cling or act like leggings. They have just enough room. I bought the matching jacket but I’m more thrilled with just the pants. The jacket fits as it should but not over my too many milkshakes stomach.

Happy with purchase
Size: Medium, Color: Flamingo Pink/White, Size: Medium, Color: Flamingo Pink/White
Acceptable product. Good fit and fabric feels nice. A little see through if you squat and have on dark or patterned under pants but if you wear undies that are your skin color, there’s no issue at all. I wish they came in a length that was just past the calf. These are a little long to be on my top go to legging for yoga. Minus one star due to lack of length options.

Well made and comfortable
Size: Small, Color: Slate Grey/White, Size: Small, Color: Slate Grey/White
Very cute and comfortable workout set! I bought the leggings and the matching sports bra sold separately. I am 5'4" , 125 lbs and bought a small in each. The leggings are tight but not too tight, doesn't dig in and doesn't roll down. Well made and thick material. Worked great for a very sweaty hot yoga class. I'll be buying more in different colors.

Fall or Winter
Size: Large, Color: Black/White
For me, these leggings are a perfect fit and perfect for Fall & Winter, maybe early Spring. Summer though, I would not dare. Comfort wise, the leggings are soft and perfect for the gym, grocery shopping, lounging, even sleep. I passed out in mine and slept just fine.
