My car having hesitation and doesn’t reach full power until hitting 3,000 rpms and making a loud popping sound coming from the exhaust . My exhaust is currently off

I meant to say I have my exhaust off *

did you hit anything or bounce off something during your rally ? I think you need rear wheel drive to "drift" , take care of the fuel smell first if there's a leak it's just not safe at any speed ,

Once I do that could there be a misfire .

do you know has the timing belt ever been done on the car , popping from the exhaust is un burnt fuel, a mis fire , check coil, plugs , wires , timing
