Hey guys-
found this post over on another website- thought I would share-
I have had the chance to do the same install and the fit and finish is superb. I like the exhaust note and it is noticiably louder both insdie and outside but not obnoxious at all when driving. The Mustang had about 3000 miles on her when she was baselined and then the MagnaFlow 15881 kit was installed. Stock was 253 RWHP and 285 RWTQ. After was between 266-272 RWHP and 290-291 RWTQ. It was a noticable gain and you can see it on the charts but you have to be careful when reading the numbers becasue of the automatic. With the shift spikes it says peak stock power was 285 but in fact you can see its really more like 260-262 and after the exhaust it more like 285-290. The dyno seems to read the highest numbers which are not right. This car was a little tricky because of the 5 speed auto but the most consistant passes are whent he car is allowed to run at Full Throttle for the whole pass, otherwise you get some of these spikes and bumps like Nino said.
If you are looking for louder they have another "Magnapack kit" which has the 4" resonators and is really supposed to give it more exhaust note. I'm waiting to see if someone else gets one of these around here but what i have now is just about right.
Dyno from 2nd gear through 4th (full throttle)
