yes they do...however i reccomend a good midpipe if you're losing the cats or it'll have a poppy tone

I run flow 40's with divorced duals and cats and it sounds pretty good. IMO

I think he's referring to catless. I have also heard that running catless will decrease low end torque. But I'm not too sure about that

You have the silver Original 40's, black Delta Flow 40's, Super 40's, and the 44's. Each sound a little bit different. The Super 40's are a bit larger, thicker than the others. Flowmaster 10 Series are nice too.

I ran true dual flow 40's on my 01 .. Headers straight out the back no cats no mid pipe with 2 1/2" tubing had 3" tips will admit sounded canned so I cut all piping off after flows always told it sounded like a v8 I loved the way it sound

The tips made it sound canned reason I chopped them off

Re: Flowmaster dual original 40's?

I added a VAP lower intake spacer when I put the first dual exhaust on. Works well on a single port, great bang for the buck mod.

Chances are you will be on the phone with them anyway, ask VAP, SSM or Morana Racing about it.
