Axlebacks

[eng90]

Hey guys ,

I have a '13 boss , it has hlt intake n arh headers with catted x .

I wanna know if i change the oem axlebacks what power gains would i be getting ?

I talked to Shaun AED and he said " no gains at all " .. None on the muffler deletes and any other axlebacks

So i just wanna make sure .. Is it true ??

Those exhaust companie always claim that axleback gives out more hp n tq

Thnx

No HP or Tq gains from axle backs. Just a sound difference.

Saw an article at LRS that showed a 9 hp gain with just GT500 axle backs.
