Love my F.I. Carbon Fiber, two issues, 1 is that I scratched the hell out of one can, not even sure how and 2, they sit a little low at the low point... Nothing major and I would buy it again...

Love my Non-Resonated FI. Only problem I see is when I lower the car is gonna be tricky not scraping the cans. But on stock ride height I have never scraped.

I thought Greddy tips are pretty huge. Do you have the Ti-C or SE? whats the diameter?

make a single!!!!

single...midpipe? :confused:

Make a quad pipe GTR style.:tup:

that would be cool, but it won't fit in the OEM rear bumper..

Loved my FI on my '09 Z enough to get it again for my '12 Z after it was totaled.

I love the sound and the gains from my Berk HFCs and Berk exhaust. I dislike my loss of gas mileage, it's hard not to go WOT to hear my baby roar!

Greedy turbo TI-C

Pros:
Removable silencers
Great ground clearance, sits higher than most by providing a relocation bracket for some electronic equipment most others force their pipes to go under
Excellent quality of welds and materials
Weight savings
Awesome sound with silencers in
Perfect fitment and ease of installation
High resale value should I decide to sell
Great looking tips
2.75" true duals
NO DRONE at all with silencers in, but still nice and loud
No need to change should I go turbo/supercharged in the future

Cons:
Not as much of a performance gain on NA cars as some others
A little too loud for me with the silencers removed


I'm very happy with my choice.

I have nothing to hate about my invidia catback.

HKS Hi-Power

- Great look, great sound.
- Great quality.
- Zero clearance issue as it's not as angled as other dual canister exhaust systems.
- 2.5" True dual H pipe.

Very well constructed exhaust. It's little bit on the pricey side but it'll hold its value.

^this

cons:
- it sets off my other cars alarm on cold starts!
- I would like exchangeable tip options (switch from burnt Ti to rolled SS etc.)

Can some Top Speed exhaust owners chime in please? Surely someone is happy or upset about their purchase and I want to hear it! I'm still trying to find a good read on the difference between mid-pipe (single pipe) and dual pipe CBE.

I have stock headers +stillen CFC+non-resonated top speed CBE. I really like the sound, it's pretty loud, but you always have the resonated option. I don't think single mid-pipe or dual pipe make a huge difference, but single pipe is def lighter than the dual pipe. And the price is amazing! I like their slide on burnt titanium tip option. I just wish the tips are bigger. And the fitment is really good. And I wouldn't complain if they decide to make dual pipes and im probably gonna get it. does that answer you question? oh and i went to a drag strip after I got my CBE and improved 0.3 sec. But I also need new tires.
