H-Pipe or Cat-back!!!!!!????

I would get the h-pipe first , you get the most from removing the cat's. I would not get the cat back until I at least get a good set of headers. But for the money you have to spend I would want the power too and the sound from the h-pipe going thru the fac mufflers is not bad , sounds better than stock , but in the long run get SPINTECH mufflers , they are the newest out andn the number show that they out perform the flowmaster and the rest!!

Oh and I have headers , h-pipe and cat back system and I got my H-pipe first things first !!!!!!!!!
