1 This exhaust is available in either aluminized or T409 stainless steel. It is a direct bolt-on application that literally installs in about 30 minutes. Our install, which included removing the stock exhaust from our Tundra, took 27 minutes: We timed it. We chose the stainless-steel option for our truck knowing we would be seeing plenty of hard miles ahead. The thick 16-gauge T409 stainless steel will not rust and has reinforced welds at all vital points surround the system.1 This exhaust is available in either aluminized or T409 stainless steel. It is a direct b There are a few things our project Tundra is lacking: more wheel travel, more ground clearance, and a solid exhaust system, to name a few. Before we begin to tackle a new suspension design, we need to get the truck sounding like a truck, give it a few extra horsepower, increase the torque, and make sure the system will work with the new setup. Anyone reading this who has built a prerunner or even a big articulating rockcrawler can attest to muffler pipes getting in the way. Typically, the only way around that is to get out the Sawzall and start chopping. Well, not anymore. MBRP Performance Exhaust has a brand new system designed to cure our woes and embrace that big horsepower sound we all wish for in our hearts. 2. Here is the main problem with continuing to use a stock exhaust when you plan on adding a long-travel rear suspension. The over-the-axle stock pipe will get in the way and if you choose to leave it, it will quickly become battered and beaten restricting airflow.2. Here is the main problem with continuing to use a stock exhaust when you plan on adding 3. Our truck is a ’10 Toyota Tundra V-8 Double Cab model that carries quite a hefty stock exhaust system underneath. Without getting too far into the details of removing the stock system, we simply unbolted the pipes from each of our two catalytic converters and pried the muffler and exit pipes away from their respective rubber hangers. Stacked next to the MBRP setup, you can see quite a different in size, length and weight.3. Our truck is a ’10 Toyota Tundra V-8 Double Cab model that carries quite a hefty stock 4. We then installed both of the provided forward pipes to each cat and securely them loosely with the original OE bolts. It is always best when installing multiple connecting parts to leave all securing bolts loose until everything is setup properly in place. Don’t forget to go back and tighten everything down at the end.4. We then installed both of the provided forward pipes to each cat and securely them loos 5. Both pipes leaving the cats measure 2.5 inches in diameter. 6. The new MBRP exhaust uses the same factory rubber mounting points making install quick and easy. The connecting clamps are also provided. Be sure to install these in a direction that allows them to be easily tightened.6.

Our new stainless-steel muffler hangs from the rearmost rubber hanger and exits out a 3.0-inch-diameter pipe that turns down just before the rear axle. Combined with the sturdiness of the system itself, this quick exit will allow our axle to swing as far as it needs to when our new suspension goes on. This is a great choice for prerunners, race trucks or even lowriders given the added ground clearance it provides.7. Our new stainless-steel muffler hangs from the rearmost rubber hanger and exits out a 3 Did All That Bling Do Any Good? Before completing this article we put a good 800 miles on the truck to allow the exhaust to break it and get a good feel for any changes we hoped to feel and hear. From the day we left Off-Road Evolution who we have to thank for helping us with the install, the truck finally started to sound like it actually had a V-8 under its bonnet. The Tundra comes with almost 400 horsepower and it’s a shame you cannot hear it with the stock exhaust. The MBRP system wakes it up and leaves you all tingly inside roaring off the start line while not giving you that annoying 60 mph drone as you continue down the road. While putting in long highway miles over mountain passes we noticed the truck needing to downshift less. The increased torque helped keep the trucks rpms down while providing increased power. So far we only have good things to report back. Quick install, tough materials, good looking and a strong V-8 purr keeps us happy behind the wheel.
