Have a quick question.
Does any of the axle backs help with hp on our cars? I thought about doing the catback but I had a catback in my last car and it was too loud to carry VIPs with the catbacks.
I'm wanting a nice deep sound but something that won't be noticed too much. Does anyone have any suggestions?
I know there's UR axle backs and the hks legamax axle backs. I don't know if anybody has axle backs here. If so what are your experiences with them??

Thanks in advanced

 

i had the UR axleback then i upgraded to cat back

IMO the catback with resonator isnt much louder than the axle back

and no it doesnt do anyting for performance, I hit the drags right after i got it and I got the same times

 

An axle-back is only for sound and looks, no performance gains

 

do catback and if you want take the stokc cat out you will gain alot.
