Which exhaust system is the best one?

Hmmm yeah but I wonder if it is just personal preferance. I had just the hitech CBe on my 350 and found it to be pretty quiet, I sometimes wanted more. So I'm guessing the stillen would be very similar in terms of noise so HFCs might make it just right for me lol

Hey all, sorry for no reply as of yet but have been at work the last two days and shift work dosnt really allow much time to post, plus i hadnt notice this thread. Well my link -> SEE HERE has a few vids in it (adding photos tonight). NONE of the videos of any of the exhausts do them justice.

I went with the Fast Intentions RTP's, CBE and CF uffler (Sale Thread) based on the videos i had heard. The Stillens sounded great also, but my ears at least thought the F.I. was that bit deeper and the sound that comes from them at High RPM is just great. Now from the videos to what i actually hear is different. The difference being is that it is much LOUDER than it appears in the videos.

Others that have done either the F.I. or Stillen setup have said the same. I was surprised at first at the Volume of it, but Tony (F.I.) did advise me first that it will be loud also. Unfortunately with not many in Aus having either it will be hard to hear them in real life. Price wise they are very similar, but the F.I. having a few more options available. Customer service and Build Quality i beilive after reading a lot of the threads here and other forums, i would in favour of F.I..

Lastly and in 2nd place for myself (sound being #1) is the Power Increase. I did get the car Dynoed when i did the exhaust install (u can see basline in my thread). After the exhaust install it did have nice gain, with ATLEAST 10hpatw from 2000rpm. I havnt posted the total figure yet or dyno sheet, as i want o let the ECU "Learn" first. Will be going back on Monday for check up and dyno. There was a 20hpatw+ gain though.
