Exhaust Systems for Your 6.5 Turbo Diesel: A Buying Guide
Are you looking to upgrade your 6.5 Turbo Diesel exhaust? Great! This guide will help you choose the right one. We’ll cover what to look for, what materials are best, and how to tell a good exhaust from a bad one.
Key Features to Consider
When choosing an exhaust, look for these important features:
- Diameter: The diameter is the size of the pipe. A bigger pipe allows more exhaust to flow out. This can give your engine more power. Most upgrades go from 3″ to 4″ diameter.
- Type: There are different types. Some are “cat-back,” meaning they replace the exhaust from the catalytic converter back. Others are “turbo-back,” replacing the whole system, including the downpipe.
- Muffler: The muffler makes the exhaust quieter. Look for a muffler that fits your needs. Do you want a loud roar, or a quieter hum?
- Tips: Exhaust tips are the end part of the exhaust. They look nice. Choose a tip style you like.
- Fitment: Make sure the exhaust will fit your truck. Check the year, make, and model. A good kit will bolt right on.
Important Materials for a Good Exhaust
The materials used matter. Here are the best choices:
- Stainless Steel: This is the best choice. Stainless steel resists rust. It lasts a long time. It can handle the heat.
- Aluminized Steel: This is a cheaper option. It has a coating to prevent rust. It’s not as good as stainless steel. It may rust faster.
- Mild Steel: Mild steel is the cheapest. It rusts easily. It’s not a great choice for exhaust systems.
Factors That Affect Quality
Several things affect exhaust quality:
- Welds: Good welds are strong and airtight. Look for clean, smooth welds. Poor welds can leak.
- Thickness: Thicker pipes are more durable. They can handle more heat and last longer.
- Bends: Smooth bends allow exhaust to flow better. Look for mandrel bends, which are smooth.
- Brand Reputation: Some brands are known for quality. Research the brand before you buy. Read reviews.
