I'd like to put a Flow or something on my 4.6L 2004 STX- but it's a work truck, so I want out as cheap as possible since it'll be out of my pocket. I'm not getting a catback, I want to cut out the muffler, replace it with something else, and have some noise just because I can have it. I don't want obnoxious, but I do want obvious.

If I put on a Flow and downturn it, will I get vibration inside the cab or not? I'd prefer noise outside to noise inside.

What series, etc should I get?

In importance:

1. Sound
2. Price
3. Power Loss

 

40 series... keep the stock tailpipe and get more pipe to make up the difference. Should have a nice rumble and be pretty quiet in the cab.

 

sounds good. Thanks for the recommendation!

 

I seem to be stepping in a little late, but akford351 is right on. the flowmaster 40 series is going to sound nice since you still have a cat. if you yanked the cat off, I'd recommend the 50 series, though.
