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. After the manifold, the exhaust passes thru two (2) catalytic converters. Unless you intend to race this thing off-road, there’s no good reason to remove your catalytic converters. First of all, it’s illegal to do so. Second, it’s bad for the environment. Third, and most significantly, they really don’t result in that much of a hp loss. Today’s designs are fairly performance friendly. From the catalytic converters we come to the factory muffler. The factory muffler is good in terms of efficiency, but not good in terms of character. The factory system is quiet and the V8 can't be heard. While many will tell you that you'll get better performance changing the muffler, keep in mind it's going to be very small. Less than 10 hp or lb-ft of torque (at best). But, it will sound better and every hp counts. As luck would have it, there are literally hundreds of mufflers to choose from. Finding the right one is tricky, but here are some guidelines. First of all, find out if the muffler you like is going to have any "exhaust drone". Exhaust drone refers to the sound of the engine running while your driving at constant speed, like on the highway. Many people prefer not to have any drone, but others are willing to deal with some drone if it gets them a little more power. Finding out if the muffler you like is going to drone is easy, ask the people at the local muffler shops as well as the websites www.tundraheadquarters.com and www.tundrasolutions.com. 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. Last, what is the best material for your muffler? While stainless steel is lightweight and resistant to rust, a lot of people that live in dry climates don't need it. Standard galvanized or aluminized steel is fine. However, if your climate is wet or near saltwater stainless steel is an excellent choice.
