Ok, I switched back to the stock muffler.
I tried it and figured I should switch back to stock and see what the real difference is.
HOLLY SH*T!!! Apparently I forgot how quiet the A3 was, I'm leaving the stock muffler on, and also replaced the torn pre-filter tube.
I guess you have to try it to see the difference, at the time when I switched it didn't seem so loud, but after putting the stock muffler back on, it's like night and day.
So... You guy's were right, I was wrong, but I'm proud to be able to admit it
I still like the straight pipe sound better, but wow, it's ridiculously quiet.
