do i have to have a muffler on my car for back pressure for it to run right?

 

without it cops from miles away will find you

 

I went to the drag strip a couple nights ago with only a RB header and a turndown. Car ran great.

 

and so did the wildlife in a 2 mile radius when they heard it run

 

If you've got a stock exhaust with all the converters and no muffler, it actually isn't very loud and sounds surprizingly good.

 

so i don't need it for it run the way it's supposed to

 

nope it should run better at higher rpm with less back pressure

 

cool because the cops haven't pulled me over yet after my muffler got ripped off

 

Yeah it was LOUD!! Lined up twice with my buddy and his S4 TII that was running JUST an RB downpipe from the turbo We were rivaling the pro-drag cars in the amount of decibles

Oh, and I beat him BOTH times Needless to say, his TII isnt running as good as it should....
