Will these fit a 2004 ford crown victoria interceptor ?

universal mufflers do not directly fit any application . They require measuring , cutting adding pipe etc . Direct fitments are under cat back systems .

Will this fit my 1997 k1500?

Yes, the Flowmaster 42541 40 Series Muffler - 2.50 Offset IN / 2.50 Center OUT - Aggressive Sound, Black will fit your 1997 K1500. It is a universal muffler, so it can be fitted to any vehicle with a 2.50 inch exhaust system. However, it is important to note that the Flowmaster 40 Series mufflers are known for being loud. If you are looking for a more subdued sound, you may want to consider a different muffler series, such as the 50 or 60 Series.

spec say it wont fit but it has the same demensions and intake and oulet pipe size, will it fit on my 1997 dodge ram 1500

If the pipe inlet is 2.5 inches and the pipe outlet is 2.5 inches, it will work.

Is this muffler lound on the inside

It dose resonate inside the car quite a bit
