Does axle back exhaust really add any HP?
I know exhausts are mainly for sound and looks but have read they do add a little HP around 5-10. I know I won't feel this, but I'm wondering is there any proof. Any tests that show an axle back only (I have awd) add HP? And which ones add more? I'm particularly interested in the tanabe medalion

Thanks guys. Some additional searching and I found this thread from 2006 which has dyno results on is250 on page 2 https://www.clublexus.com/forums/per...is250-rwd.html

You can replace your factory system with an aftermarket cat back.
It looks better
Sounds meaner
But wont do anything as far as performance because the power gains are so minimal. You cant actually "feel" 2-7 hp.

It will add a little bit of HP but not as much as changing the whole catback system. Most of it is in your head that your car is faster by changing just the axle back maybe because it sounds louder.
