If your looking for quality go for FI

If you are looking for quality and performance go for Stillen.

Thats why it took them three time to get the intake right for the G37 and two times for the exhaust, do your research

Btw remember weve been dealing with this motor and stillen long before you even had your car

FI is definitely louder. Has a different tone than the Stillen as well. The CF resonators also add a bit of flavorful tone to the mix.

Simply put, the 18" resonators are not as loud as the 12".

Both CBE give a decent performance gain. As for me, since I already have Stillen bolt ons, I'll end up choosing the Stillen CBE.

The FI TDX CBE is lighter than stock esp w/ the CF resonators.

The Stillen you will be adding +11lbs over stock exhaust. But, the weight is towards the rear section: the muffler, which should help with traction since it is a RWD vehicle.

In terms of reducing weight and balancing out the car, it's so much easier to remove weight from the rear (spare tire, trunk liners, tools, amp, subs, etc) as opposed to the front. In doing so, you lose your Front/Rear balance for cornering. This is why people relocate batteries to the rear to balance out this weight as an example. The Stillen CBE's additional weight being in the rear helps offset this balance. So I don't think adding weight is really a setback.

I love the sound of both CBE but I think the FI CBE is a tad on the raspy side. You will definitely have some drone at higher RPMs as heard from the videos, but it's not bad and I doubt your girlfriend will hate it. IMO the stillen cbe has the best of both worlds: sound and performance.

In terms of looks/aesthetics, FI has it hands down. But if you're only into looks, try also looking at the Greddy SE exhaust or the HKS exhaust. The tips look amazing.

In the end, to each his own. I think the Stillen balances performance and sound while the FI CBE balances aesthetics and performance.

Good luck

I went with Stillen for a number of reasons:

1. Cheaper
2. Immediate shipping
3. Better ground clearance
4. "Safe" noise level (no drone or rasp...no risk of regretting it's too loud)
5. Enhances the car's stock sound without making the car sound completely riced

Some potential drawbacks:
1. Fit and finish is very good but not up to FI's from the pics I've seen (not sure this is a big deal considering it's under the car and the tips look great)
2. Loudness level may leave you wanting more, eg HFCs or testpipes. It's a great improvement over stock and about as loud as I could tolerate...but I still wonder what HFCs would sound like in person with it
3. Less exclusive. Stillen sells hundreds of these. FI's list is available online and has less than 60 installed. If you want exclusivity, Stillen isn't it.

I'm thrilled with my choice of Stillen. The sound and loudness are perfect and leave me the option to do other bolt-ons like HFCs with more wiggle room before I get into drone, rasp, or ear-bleeding noise levels. Many with the FI CBE have taken the HFCs off since it's too loud and drones.

Still like the stillen sound the most out of all the exhausts I've heard. It doesn't sound like a tuner car, sounds like the car was meant to sound like this. Performance wise....numbers speak for themselves. I'd still choose the Stillen if I had to choose over again. In fact the only thing I wish is that it were a little louder (even after HFC's). The only thing I would replace it with is longtube headers or something more race-inspired.

i dunno why but a few weeks back my stillen started to sound so raspy especially when accelerating
i mean the deep tone is still there but the rasp sound is similar to those in "fart can" exhausts(and i hate it)

i dont know if theres a leak or not but visually i dont see any
so im actually thinking of changing it later(if $$ permits)

How do you know it's the Stillen CBE and not your Berk HFCs?

lol i dont
but it was just recent i started hearing the raspy sound and the only thing i unbolted recently was the mid pipe and rear part of the exhaust to get the sways installed

i might need new gaskets tho so that could be the issue...for now im just living with the sound

but who knows it mite be normal and i just never realized it
*i have yet to see 1 in my area with the same setup

I don't know if you'd get the Stillen free shipping outside of the US, but it's worth asking.
