Helpful Notes
- Outlet styles: Many upgrade turbos use HX40-style 4.0" outlets—pair with the correct downpipe.
- Pipe size: 4" suits most tow/daily builds; 5" reduces restriction/noise further but needs more space.
- Brake types: Remote-mount vacuum or air-actuated kits (PRXB) add safe retarding on grades—great for heavy trailers.
- Hardware: Use quality V-bands and band clamps to prevent leaks; re-torque after heat cycles.
Frequently Asked Questions
Will a 94–02-listed exhaust fit my 1994–1998 12-valve?
Yes—most systems cover 1994–2002 5.9L trucks; your 12-valve years are included. Always verify product fit notes.
Do I need an HX40 downpipe for my turbo upgrade?
Many S300/HX40-outlet turbos require a 4.0" HX40 downpipe to match the outlet and body clearances.
Exhaust brake: BD vs Pacbrake?
BD 1037135 is a proven 4" remote-mount vacuum-actuated option; Pacbrake PRXB kits offer strong low-RPM braking with air actuation. Pick based on control style and trans type.
4" vs 5" turbo-back—what should I choose?
4" is ideal for towing and stock-to-mild power; 5" flows more and is quieter at cruise but is larger to route.
Are stacks street-legal?
Rules vary; stacks are commonly for off-road/show use. Check local laws before converting.
