Im selling my invidia exhaust on friday and picking up my ark the following week. Will I run into any other problems besides losing power and being really loud by just running hfc for a few days?

 

You might get pulled over due to it being really loud

 

1) Way too loud.
2) Hot exhaust gas flowing in the wrong place.

 

I have done it before, so loud your ears ring after you get out of the car

 

Well this is going to suck lol plus I have hfc.. omg

 

lol man...I was running no exhaust with ART pipes for a few days until I got my Y-pipe made. It is sooooo loud and annoying to drive, you have no idea. The drone rattled my head. It sounds really good though if you keep the RPM's under 1500

Edit: Your torque goes out the window as well. Although I only tried hitting the pedal once or twice since it's too loud and annoying.
