i dun think that these method is safe...cos the size on the outlet is big...then suddenly all the pressure are forced thru a small hole...if the screw is not a hardcore one the baffler will one day fly off and hit the vehicle behind u....shud have at least have a tube to make the airflow smaller in slow process...how to explain aihh...look below....the baffler shud have the extension so that there wont be a sudden change in airflow velocity....failing to slow this process it'll only create an intense pressure inside wor....see below...usually exhaust have a wee bit smaller inner thinggy(fiber parts)...the baffler's extension shud at least be the same size as this....of cos this is my 2 cents ler...but if u wanna do this method...at least use 3 screw holes to make sure the thing wont fly off ler..ehheheheh
