Hi guys, fitted my cat back exhaust a couple of weeks back and basically i find that wen the engine is running when i drive away im leaving pools of liquid directly below wer the joins are in the exhaust, the joins are tightly clamped but ive watched it and wen the engine gets warm it is dripping water, doesnt smell like fuel or anything different, i have only noticed it doing this since i fitted the exhaust, is it normal??
