Are they really worth it? i mean people are running low 12's and 11's with Tunes and CAI's... anyone have an offroad pipe and decided to go back to the stock midpipe??
I think u have that confused with catbacks because there are always good gains from getting rid of the cats and the neck down onthe 2011 is horrible for flow. The gains are on the same lvl as a Cai for that matterMidpipes wont give you that much if any additional power. People mainly get different midpipes for sound.
Not confusing it for catbacks but midpipes may affect the new 5.0s more than they do 4.6s. Kenne Bell tested a K/B superchared mustang with an o/r h and the stock catted h. There was no difference in hp nor tq. Stock cats vs hi-flow cats vs no cats may affect an N/A car a little more. Here are a few of my dyno numbers with my mods at the time. Difference is in the midpipes. Dynos runs were on the same dyno in nearly the same conditions-I think u have that confused with catbacks because there are always good gains from getting rid of the cats and the neck down onthe 2011 is horrible for flow.

Stock catted H: 298 RWHP/308 RWTQ
O/R Prochamber 302 RWHP/305RWTQ (I could feel a loss of low end tq)
Prochamber w/hi-flow cats. 305RWHP/311 tq.

i start with the prochamber. not a good design ether way. and as far as the kenne bell thing....well beleive what you will but thats a bunch of crap and i do beleive i see more mustangs than kenne bel to support that (i'll say probably around 150-200 a year)and dyno them with different combos...Z28this in this thread can vouch for that one

I'm waiting for someone to release a mid pipe with hi flow cats for the 2011 5.0. My question is, not carrying about smog, smell, or horsepower, is there much sound difference from a high flow cat to no cats. Iv ran hi flows on my last two 4v mustangs and the sound was perfection with bassani cats and mufflers. I'm really close to pulling the trigger on a lethal x but do want to be way louder than my hi flow threshold.
