Toyota's new Tundra is powerful. It is a capable hauler and tower, and it's as fast as many sports cars. But does your new Tundra's exhaust need modification? For instance, do you want to hear that V8 rumble or are you trying to get more power? Fortunately, the factory exhaust system is efficient and doesn't require much modification. The new Tundra comes with a 4 into 2 into 1 exhaust manifold, which has been found to be most efficient for moving exhaust gases quickly. The exhaust manifold is also made out of stainless steel, which is light and resistant to rust. And, the exhaust manifold has equal length exhaust tubes making it as good as most products available after-market. In short, the exhaust manifolds on your new Tundra don’t require any modification. The next components the exhaust gases travel thru are the catalytic converters. There's really no benefit to changing or modifying these, and taking them off is a bad idea. Today's modern catalytic converter is very efficient and it's legally required equipment. Makes sense to leave them alone. After the catalytic converters, the exhaust gases from each side of the motor cool somewhat and meet-up at the muffler. Again, the factory system is pretty good. You won’t see a significant hp and torque gain by replacing the factory muffler (3-5hp, 5-10ft-lbs at the most), but you will HEAR the truck better. The rumble that you'll hear if you do this is intoxicating, but there are about a hundred different mufflers to choose from to help you get the rumble you want. TRD, Borla, Flowmaster, Gibson, Edelbrock, Magnaflow, etc all offer quality products. While brand is important, it’s more important to know what you want. First, do you want to hear the exhaust ALL the time? In other words, when you drive down the highway, is a little exhaust drone OK? If not, make sure you choose a muffler that's not described as being loud. If you ask your local muffler shop or visit websites like www.tundraheadquarters.com or www.tundrasolutions.com you can find a good muffler. Second, do you want something that people can slightly hear when you drive by, or do you want something so loud that the neighbors know exactly what time you leave for work every morning? I hope that it’s the former, but if you decide for the latter, look for words like “racing” or “glasspack”. You also need to decide if you want a single or dual exhaust? In terms of performance, you usually see the best increase by copying the factory system but upgrading the components. On the Tundra, that would be a single exhaust. But since you’re not going to see much of a performance difference either way, dual exhausts do look and sound better, and that would be my suggestion. Finally, what material is best? We think that’s a decision that should be based on geography. If you live anywhere near the corrosive effects of saltwater, stainless steel is the smart choice. While it’s more expensive up-front, it will last much longer than galvanized or aluminized steel. People living in dry climates really don’t need to purchase stainless steel — if rust attacks their system, it will be years before anything is damaged.
