Stillen is very nice, it is louder than stock but not excessive. On the highway it is barely noiticeable and when you get on the gas it give the car a real exotic sound and I highly recommend it. Also, you can feel the seat of the pants difference in power, it is the highest dynoing exhaust you can buy for a cat back system. Fit and finish is also very good.

 

Say Stock Sound is 0 and Extreamly Loud is 10

Nismo would be a 4
Stillen would be a 7

I had a Stillen before I switched to Nismo... I did like the Stillen for its power, but it was just a tad to loud for my personal taste. The Nismo is a nice compomise between power and noise.

 

Weird, I quoted the wrong post in my previous post. Anyways, I meant to agree with this guy. I am really happy with the Fuji. And I'd say that it's probably a 3 at idle on the previous scale.

 

HKS , has the New Dual Hi-Power now! We've just been informed by HKS USA this new cat back system is NOW IN THE US!. The press release date being yesterday. You guys are amoung the first to find out. High polished stainless steel dual exhaust and dual titanium tips. As usual HKS has outdone itself with their R&D and the fitment is perfect. Just like all HKS peices its arguablely the nicest one on the market.
