As talontid stated, there is no difference in sound/power from using OEM vs aftermarket connecting pipes. Aftermarket connecting pipes will allow to keep your OEM system unmodified since the connecting pipes are part of the OEM muffler system.
Axlebacks provide 3 essential changes over OEM systems:
- Weight Savings
- Exhaust Note/Tone
- Tip Design
It's rare power gains are achieved with any axleback system.
