Is there any gain in horse power with adding the EVO Magnum slip-on exhaust?
This is my take as well.I called EVO, and they said about 4 hp and an increase in throttle response. I ordered it, and will be happy with just the sound difference, if nothing else.![]()
what is Wideband O2 and intake mod and do u have linnksI went with HMF full exhaust and tuner with Wideband O2 and intake mod. The sound is super!
According to HMF and tune 11 HP gain.
Rough estimate is about $180/HP.
