Our X-pipe replacement has no effect on tuning of the exhaust.

It simply replaces stock resonator with an X-pipe design that alters the sound, not power. Our X-pipe is dual 3'' vs. fatcory dual 2.75'' and internal diameter of the merge is over 4.5'' overall diameter, hardly what I would call restrictive.

15F difference in temperature can easily account for performace difference.

Lex, try it in the same weather and you will be back to where you were.

Have fun!
