Agency Power Catback

Anybody have any sound clips of this exhaust. Only one I could find was the one straight from agency power and it sounds awful with the BOV swooshing every 3 seconds. I searched but could only find posts that were to private videos that I could not access. I read that general consensus was that the exhaust sounds terrible. Just looking to see if there are any clips to prove otherwise.

I'm assuming this is the one you already have seen...

Yes that is the one. With the BOV swoosh every 3 secs. That and the quality of the video is not very good. Just looking for a better sound of the exhaust before I purchase it.

Every video I've heard of the AP exhaust sounds terrible...

I guess I'll find out soon. I went ahead and ordered one because I had a hook up on it, so we will see. I can always sell it if its that bad.

i have the agency power exhaust and i love the sound, its a little loud around 2000 rpm. . i have some really bad rattleing right now when its cold but i think it just needs to be tightened up. were haveing a bit of trouble getting the tips lined up perfectly and i wish they stuck out more than they do but for the price i thinks its a great buy.

Nice, glad to hear somebody is happy with it. Do you have any leaking from it due to the clamps?
