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.

Half gone in the first 45 minutes...
Size: 6 Inch, Color: Bone
our medium sized dog is an aggressive chewer but we expected mire than 3/4 of an hour before the bone's demise. Half gone quickly, heavy stitching included, so threw away the second half for fear of a blockage. Not safe, not durable, disappointing. Sorry, cannot recommend this one.

Puppy loves it!
Size: 6 Inch, Color: Bone
I have a very energetic lab puppy - this chew kept her still for longer than any other toy I’ve tried (besides bully sticks and peanut butter). Highly recommend!

Good for an aggressive chewer
Size: 6 Inch, Color: Bone
My dog loves it. These last a long time. My dog is a Rottweiler/American Bulldog mix, she goes through a lot of toys. So, I try to buy her something that has no stuffing, but will keep her from getting bored. This one has lasted about 6-7 months, the leather is chewed off, but it's still the shape of a bone. I did just order another though, the one she has is a little stinky from her slobber. :-)

Not as expected
Size: 6 Inch, Color: Bone
I have been looking for these ever since we got a similar one at Sierras for our 1 1/2 yo Cane Corso. She is brutal on chew toys and the first one from the box store held up well. However, this did not hold up as well and she was done with it in less than a week. Still looking for that perfect toy.

More durable than expected.
Size: 5 Inch, Color: Raccoon
I was walking through my front room the other day when I noticed a suspicious spot on the floor. It looked like something I should not touch without gloves. As I got closer, I realized what it was. It’s the ‘guts’ from this toy. My dogs (Pit Bull and German Shorthaired Pointer) were each given one. Both are aggressive chewers with their toys. They ATE the faces off these toys and now play with the felt interior. I’m still trying to figure out how they ate through leather while the felt remained intact. Regardless, they still play with them. Now they are basically semi-fuzzy throw toys we can throw in the house because they don’t leave marks on the wall if our aim is off. Sometimes things work out the way they should. :)
