AAM short tails and mid pipe is deep until 3k, then it hits a higher pitch, more GTResque in the mid, then higher pitched up top. Fast Intentions is deeper overall, but not as loud. Removing the cats will make everything loud though. Just be careful as it can introduce rasp if your exhaust doesn't have much for mufflers or resonators. I'd recommend resonated testpipes, HFC, or resonated HFC. If you replace them with long tubes, do yourself a favor and get at a minimum a F.I. exhaust with 12" resonators, or the AAM with the axleback muffler.
