Frequently Asked Questions

Will this fit my F-150 if I have a different bed length?
No. This specific part number (B928-C920-C) is engineered for Super Crew cabs with a 6.5ft bed and 157" wheelbase only. Thermal R&D makes separate part numbers for other cab/bed combinations.

Does this exhaust cause cabin drone?
No. True Helmholtz Technology is specifically engineered to cancel the resonant frequencies that cause drone, so you get a clean tone at all RPM ranges.

Do I need to cut or weld anything to install this?
No. This is a direct bolt-on system that connects to your factory catalytic converter/downpipe and uses your OEM exhaust hangers.

What tools do I need for installation?
A basic set of hand tools, a jack and jack stands (or a lift), penetrating oil for factory hardware, and about 1-2 hours of time.

Is this exhaust louder than stock?
Yes, it produces a noticeably more aggressive tone than the factory exhaust, especially under acceleration, while remaining civil at cruising speed thanks to the drone-cancelling design.

What is the tip finish?
This system comes with a single coated (black) exhaust tip.

Does this affect horsepower or towing capacity?
This system improves exhaust flow versus the factory system. It does not alter your truck's rated towing capacity.

Is there a warranty?
Yes, Thermal R&D backs this system with a Lifetime Manufacturer's Warranty against defects.

Installation Instructions

1. Raise the vehicle safely on a lift or jack stands and allow the exhaust to cool completely.
