Ok so i was driving home from town today and i go to overtake a slow car, i dropped it down from 5th to 4th pull out and floor it then the car pulls as normal (not much) then wooosshhh my car flys off. I hear a small pop sort of noise and look in my mirror so see a big cloud of dust and feathers or sumut behind me. It must have come out of the exhaust, so what was it do you recon? Just a build up of sh*te that was stuck?
Any ways doesnt realy matter as im happy coz the car is sooo much more responsive now so im happy.
