Sorry about the image quality, the paper got crumpled. This is with zero tuning. Magnaflow x-pipe with cats and magnapack mufflers. It gained as much as 10 hp in some places and 15 ft/lbs in some places.

The edge of the paper with the final numbers go cut off. 275.70 hp and 292.23 ft/lbs max.

I think that is the first dyno I have seen with just exhaust results. Good info.

Is there a difference with running Bassani X pipes performance wise?? or is it just the way it sounds that makes the biggest difference?

The new mufflers aren't going to be making the new power, its the new cats/x-pipe that is giving me the new power.

And magnaflows Xpips and mufflers are just as high quality as the bassani series???? cause i dont want my mustang to be 'deafining' loud... just cool and i was wondering if you had a sound clip or something???

There are 2 different magnaflow muffler kits. One is quieter than the other. The one I have is basicly a straight pipe with cats and dummy mufflers. So it's REALLY loud.

hopefully everyone with dyno results on their exhaust will post in here.

Is that good? i thought 300 RWHP is the rating?

the 300HP is at the crank. Most are seeing an average of 260 - 270rwhp. without mods.
