Hi, so far reading on this forum, I saw alot about the SP2, but not so much on the agency, I'm thinking of changing the exhaust soon (my stock muffler is damaged when thanks to the steep chinese stores on Colima)
I was wonderin whether the Agency would be better than the SP2, and I can't seem to find a dyno chart for the agency

 

I don't think there will be much of a hp difference if any. It boils down to how much you want to spend. I have the greddy and love it. As far as the sound....the draw of air into my custom intake made of 4" dia aluminum pipe is louder than my exhaust.

 

I have the SP2 also, and EVERYONE loves it, even my GF. It's got performance sound, but it's still mellow when you just want to cruise. I've got a few VQ35 guys (G35/350z) with Borla systems tha tlike the sound of my SP2 better.

 

no one on this forum has an agency!?!?

 

There is someone in the for sale section selling one. Why don't you PM them. I haven't heard of too many people with that exhaust though.

 

haha, bringing this back from the death in which it came from

no one with agency?

 

ido. i like it. its a bit too loud at first, but you'll get used to it. Keep in mind that i have the cat less midpipe that comes with the exhaust. Maybe thats why its louder. As for performance, i think the borla and the agency are about the only ones that actually showed some performance gain. (very minimal though)

 

I ordered an agency exhaust a few days ago. i'll be gettin it delivered tomorrow. i will post pictures before and after install.

 

wtf I made this thread? I'm such a noob

 

I have an Agency exhaust setup (with race pipe). But since I had to purchase a winter vehicle instead of the MazSport turbo I plan on putting the cat back on until then (even then I might just get a high flow cat). With the race pipe you can notice a little gain in the higher band, but will see real gain once you go FI.
If a loud exhaust and nice flames are what you are looking for, the Agency is a good pick.
