Thermal R&D 3 Inch Front Pipe Back Exhaust for the 2018-2022 Honda Accord with Ceramic Coated Tips
The Thermal R&D B191-C191-C is a complete 3 inch front pipe back exhaust system built specifically for the 2018-2022 Honda Accord Sport 1.5T and 2.0T. Starting with a 3 inch main tube that splits into 2.5 inch tailpipes, T304 stainless steel mandrel-bent construction increases exhaust flow and delivers a deeper, more aggressive exhaust note compared to the stock system. True Helmholtz Technology cancels the resonance frequencies that cause cabin drone at highway speeds, so the B191-C191-C sounds great at wide-open throttle while remaining completely drone-free on long highway drives. Mill-finish frontpipe, tubing, and resonator pair with brushed-finish mufflers and ceramic coated quad exit tips. All hardware and clamps are included. Manufactured in Lancaster, California by Thermal Research and Development with a Limited Lifetime Warranty to the original vehicle owner.

Frequently Asked Questions
Does the B191-C191-C fit my 2021 Honda Accord Sport?
Yes. The B191-C191-C fits 2018-2022 Honda Accord Sport models with the 1.5T and 2.0T engines.
What is the difference between the B191-C191-C and the B191-C191?
Both are the same 3 inch front pipe back system for the 2018-2022 Accord. The B191-C191-C (this listing) includes ceramic coated black quad exit tips. The B191-C191 includes the same system with polished stainless tips. Mechanically they are identical; only the tip finish differs.
Is the ceramic coating durable on the tips?
Yes. The ceramic coating is heat-resistant and oxidation-resistant, maintaining its black finish over extended use. Unlike bare stainless tips, ceramic coated tips will not turn gold or develop heat discoloration over time.
Will there be highway drone?
No. True Helmholtz Technology cancels the resonance frequencies responsible for drone at 65 to 80 mph. The B191-C191-C delivers a deeper, more aggressive sound under throttle with zero drone at highway cruising speeds.
Does this system replace the catalytic converter?
No. This is a front pipe back system that connects downstream of the OEM catalytic converter. Emissions compliance is maintained and no check engine light should result from a proper installation on a stock Accord.
Does installation require cutting or welding?
No. The B191-C191-C is a complete bolt-on system. All hardware and clamps are included. No cutting, welding, or drilling is required.
Does this fit the Honda Accord Hybrid?
The B191-C191-C is designed for the Accord Sport 1.5T and 2.0T. Contact us to verify fitment on Accord Hybrid models before ordering.
What warranty does this exhaust carry?
Thermal R&D covers this system with a Limited Lifetime Warranty to the original vehicle owner, non-transferable. The warranty covers defects in materials and workmanship and does not apply to racing, commercial use, or improper installation. Manufactured in Lancaster, California.
Installation Instructions
Allow the exhaust to cool fully before beginning. Raise the vehicle safely on jack stands. Working from rear to front, unclip all hanger isolators and loosen all factory exhaust clamps. Disconnect the front pipe at the catalytic converter outlet and remove the factory system. Install the B191-C191-C front pipe first at the catalytic converter outlet, leaving clamps hand-tight. Route the rear sections into the OEM hanger locations, centering the ceramic coated quad tips within the rear bumper. Torque all clamps to specification and start the vehicle to check for leaks.
