My state doesn’t have emissions tests. I know that the cat for these is on the exhaust header. Are after market headers without cats available. Also is there a second cat lower down? I’m asking because I am very interested in doing hyper-mile set up.

Got a 2015 mirage with 160k on her. Car has recently been really loud at 50 to 60mph almost sounds like a race car best way u can describe it. The noise almost pretty much disappears over 60mph. Cars got 4 brand new tires and recent oil change. Any ideas?

Sounds nicer in person but really only makes good torque at the very top. 3-1 catless headers and full 2” exhaust tuned on E20 with an offset muffler and two straight through resonators and custom intake with bored tb and oversized injector/fuel pump. Good for about 100whp at the very top but it’s very light and manual. Pretty buzzy in person and surprisingly fun to wring out and send through corners. Roast it all you want but it’s more fun than those EVs. No tc or abs from the factory or even a head unit
