I just installed an Ace header and went for a (slow) drive. The car sounds weird under load. Sounds normal when reving stand-still, but when driving I can hear noise from under the car from ~2500 rpm (or when pushing the throttle, hard to tell).
I figure I have an exhaust leak between the overpipe and midpipe, or possible just a skid plate rubbing (common for Ace 350). I did however hammer out the skid plate.
Anyway, I'm no expert and would like to know if the log looks OK to drive the car for a while (to get some soot at the leak or marks on the skid plate). Thanks in advance!
