Why Upgrade to a High Flow Front Catalytic Converter?
Your factory catalytic converter is designed to restrict flow (because emissions). Over time, it gets clogged and makes things even worse. This upgrade helps fix both problems:
- Improved exhaust flow – reduces restriction vs stock
- Restores lost horsepower – especially if your OEM cat is failing
- Better throttle response – less hesitation and lag
- Helps clear check engine lights – common fix for P0420
- Direct-fit design – no fabrication, no headaches
Basically, your car starts acting normal again.
