Please explain to me what statistical facts or dyno charts you have to support your THEORY of losing cats = more HP. It is BS plain and simple. I challenge anyone to take a stock GT and put it on a dyno with cats, and then put it on the dyno without the cats and see a HP increase.
(good luck)

RE: H-pipe
After I purchased my O/R H Pipe from Brenspeed I asked him about the H pipe making more power (website says 8whp @ 5000 rpms and 10lbs of trq and that this was done by an independent company comparing it to the stock catted H pipe):
Me:
I just recently bought the pypes o/r mid pipe from you, and wanted to
know about the testing you did on it. What other modifications were
done to the Mustang when you tested this part? Did it have the stock
Mufflers on? Did it have UDP's? Was it supercharged? Just wondering
if you all think it is better, power wise, to leave my LoudMouths on
or put stock Muffler's back on with this mid pipe. I have C&L intake
and 93 Octane tune as my other mods. Also, should I retune after this
installation?
Brent:
The car had Mac mufflers and the C&L intake and tune. That's it.
You will for sure make more power with the stock mufflers and the off road H
pipe.
We do give free tunes with the H pipe if you have our xcal2.

RE: H-pipe
If all my 60fts are within .05 of eachother, and i cant mess up shifting, track conditions are very consistent lately. My car runs slower with the cats. So my car makes no more power with them off and just decides to run faster when there not on? The car obviously must make more Ive been drag racing for years, and im at the track twice a week year round. I wish other days my car would just decide to give me more power. How else would you explain it?
