[DMCForum] Re: Airflow question?

["Mike Walsh" <yahoo@xxxxxxxxxxxxxx>]

After seeing Bills exaust at PF, and getting a burn off my cat 1/2 
hour after a quick 10 min drive, I am determined to get the stock 
muffler, pipes, and cat out of there. The heat that radiates from the 
stock exaust setup is unbeleiveable. 

As for air flow, a couple of weeks I was playing with a can 
of "canned air". It was the kind used to blow out computer parts. 
Just for the hell of it I sent a quick squirt towards the right vent. 
Almost immediatlly the engine began to labor. I did not squirt it 
down the vent, just towards it, so I am sure the vent sucks air (at 
least when parked)
