I must say I finally was able to hear the 18" carbon fiber setup on my buddies Nismo last night and it sounded great. He installed it 2 days ago and couldn't be happier. He also got the resonated test pipes but was unable to install them for whatever reason.
Just wondering, perhaps it's discussed in the other 350 pages that I'm not about to read through.... is there much of a difference between resonated test pipes vs high flow cats? They both seem the same to me? I guess the Res TP give you 3whp more than HFCs?
I don't think I'll pull the trigger until I hear them on his Nismo soon. But, I was actually very impressed with the 18" carbon fiber. Just a bit too quiet for my taste but I'm sure changing out the cats will take care of that for me.
