Frequently Asked Questions About Peterbilt 379 Elbows, Piping & Comp.

What's the difference between chrome and stainless steel exhaust elbows for my Peterbilt 379?

Chrome-plated elbows offer a mirror-like finish and cost less upfront, but the chrome can peel or rust over time, especially in harsh weather conditions. Stainless steel elbows (typically 304 or 409 grade) resist corrosion better and last longer, though they have a slightly duller finish. For trucks exposed to road salt or coastal environments, stainless steel is worth the extra investment. Chrome works well for show trucks or mild climates with proper maintenance.

Will these exhaust components fit my specific year Peterbilt 379?

Most exhaust elbows and piping are compatible with Peterbilt 379 models from 1987-2007, but there are important variations. Pre-1993 models may have different mounting brackets and pipe diameters. Extended hood models require longer straight pipes than standard hoods. Always verify your truck's exhaust diameter (typically 5" or 6") and measure the length from turbo to stack before ordering. When in doubt, provide your VIN for exact fitment confirmation.

Can I install these exhaust components myself, or do I need a shop?

Basic elbow and straight pipe installations can be done with standard tools including wrenches, exhaust clamps, and jack stands. However, you'll need proper safety equipment and should expect 2-4 hours for a complete system. Common challenges include aligning multiple joints, dealing with rusted connections, and ensuring proper clearances. Turbo-to-pipe connections often require special gaskets and precise torque specs. If you're replacing the entire system or modifying pipe routing, professional installation is recommended.

What gauge thickness should I choose for exhaust piping?

Standard 16-gauge aluminized steel works for most applications and offers good durability at a reasonable price. For heavy-duty use or maximum longevity, 14-gauge or thicker is better but costs more and weighs more. Stainless steel can be slightly thinner (18-gauge) while maintaining strength due to material properties. Consider thicker gauges if you frequently haul heavy loads, operate in extreme conditions, or want maximum years between replacements.

How do I prevent exhaust leaks at the elbow connections?

Proper installation is crucial - use high-temperature exhaust sealant rated for at least 1000?F on all slip joints. Replace gaskets at flanged connections rather than reusing old ones. Ensure pipes are cut square and deburred to create tight fits. Use quality band clamps or U-bolt style clamps tightened to manufacturer specs. Check connections after the first few heat cycles as thermal expansion can loosen fittings. Periodic retightening during regular maintenance prevents most leak issues.
