Hi, sooo I installed a catless downpipe on my ST. Overall the exhaust is louder, the turbo is a lot more audible and I can smell the fumes when I step out of the car. Which is all fine...however, when my thermostat says high and my oil temp goes up then that’s when I started feeling skeptical about my installation. I had no problems before but now it’s giving me problems. Whenever I stop at a light my engine heat goes down. If I cut the car off and 15minutes later it’s back to normal. But once I begin driving it raises back up to high. Idk if I need a new intercooler or if I just have to get the tune right away, or better oil, or what? What do y’all think?
