Exhaust feedbacks?

6MT

Well, you should do some searches. There have been a few write-ups and threads on the different aftermarket exhausts.
I have the same set-up as FricFrac. The Stillen HFC & CBE combo works wonderfully. It is quite loud and has certain "resonant" RPM points that can be annoying, but all aftermarket exhaust systems have that problem.
The main thing is the gains. I love the sound that it makes & I believe it to be the sweetest exhaust I have heard.
The fit and finish on mine was top-notch. (Some of the earliest versions had some fit issues, but they have been solved.)
Stillen will give you great customer service. They also have a GST number here in Canada. That means that they can bill you the FINAL cost on the bill (no extras to pay upon delivery), which saves a lot of hassles shipping across the border.
In my view, the Stillen system is top-notch. AND, do the HFC with the CBE (at the same time). It will save you installation time (and money), and you'll see the potential of the complete system.

EDIT: I'm not a fan of the Fast Intentions exhaust. Having heard both, I like the Stillen better. But, you'll get comments and opinions going both ways.

I agree with some of yor comments, but many write-ups and dyno experiments seems to show that the FI CBE alone is putting more HP to the ground than the Stilens...

I think that is "bovine scatology". But I really don't want to get a whole bunch of people arguing about this one does "x" and this one does "x+1". As I said in my previous post... "But, you'll get comments and opinions going both ways."
