No cats or no muffler
Which would make more power, 3" high flow cats through a LoudMouth or no cats through a Hooker catback? Assume about 425 rwhp. I suspect the cats will sound better because of less rasp, but that would probably be a little louder as well.

i should be able to help a little bit here....as i've had all of the above lol
set ups in order
1. stock manifolds, ory, hooker catback....sounded great at wot, quiet at idle but deeper
2. stock manifolds, ory, loudmouth...sounds like ****, too much rasp.
3. stock manifolds, highflow cats, loudmouth, sounded better and it was nice and loud all the time
4. stock manifolds, highflow cats, hooker, quieter, more tone...all tone no drone, sounded great.
5. Pacesetter lt's, highflow cats, loudmouth...louder than all of these, but sounded better than number 2.
6. Pacesetter lt's, off road y pipe, loudmouth (just for ***** and giggles)....there is not a worst sounding exhaust period.
7. Pacesetter lt's, off road y pipe, hookercatback...probably the best sound i've had yet. deep yet quiet at idle still but more noticeable than before, and at WOT its flat out sick sounding, great tone, great bass in the exhaust, and no drone what so ever, no rasp either.
8. pacesetter lt's, off road y pipe, hookercatback and a cutout int he I pipe...exactly what i was looking for, and when i want i can make it quiet again.
so lol basically you can pick which one you wanna read and get an opinion on.

i also run FLP LT with NO CATS and a CUT-OUT with the stock SLP cat-back when i want to be stealthy.........i dynoed with the dyno open and closed and acctually gained 5 rwhp all across the rev range..... not bad for a bolt on car....un-tuned.
