Can someone please help with your eperience and advice. When you install a racing beat header on a 82 Rx7 (12a),
do you need a resonator to replace the cat or just a modified pipe. Don't want the car to loud and get bothered by the cops.
Any help is appreciated.

Thanks

I have headers and nothing else until my rice muffler shown below. Its not any louder than the hondas out there. Alot of people get presilencers.

Get a presilencer - use your midpipe, then add a muffler, preferably RB...

Good luck!
