Which exhaust is better
 

Hi,
I just bought my 370Z 2010 from US and it's not shipped yet. I purchased Takeda air intake because it's easy to install.

Also I want to buy catback exhaust, so can you help me choose the best one with sound and HP it gives:
STILLEN, GReddy, Borla, Fujimura, Invidia, NISMO,HKS and 5ZIGEN

get fast intentions exhaust and there LTH's

Fast Intentions and Stillen make the same gains, with FI, you'll have to be put on a waiting list because they're made to order. Stillen looks more stock, either way you cant go wrong, leave the others alone.

What justification do you have to say...leave the 'others' alone?

I love my Invidia Gemini - Check out my post http://www.the370z.com/intake-exhaus...omparison.html

Yalshaiba - there are enough great reviews on this site to make a justified decision. Just have to take the time to browse the video's. Really comes down to how loud you want it, price, look, etc.

Good luck!

The justification that I have is that Stillen and FI have proven independent dyno results of 15-20whp while the Invidia averages 8-10, Power and Sound is had with both, not knocking the others, but these have proven time and time again to be the best for making power, and sound great.

and are also heavy (at least the Stillen). I plan on Amuse...

Yeah, do not classify us anywhere near Stillen in terms of weight. Our system is anywhere between 10-15 lbs. lighter than stock, all depending on which options you go with.

No ones debating the weight, but a 15 lb. addition over stock is negligible.

To some people the weight factor is a big deciding factor. To me it is not, however I do not build these for me I build them for all of you.

never said you didnt have a great setup Tony, its by far the best looking exhaust out there, only thing that stopped me from getting them is the stock look of the Stillen.

The Stillen tips don't look stock at all dude! Granted you don't have the FI muffler look from behind, but the Stillen tips look dramatically different than the stock tips. The Berk CBE is the visual sleeper.

I know you didn't and I am not sweating you either. Everyone likes different things thats why it is great to have options. I will not knock Stillen with trash talking. There is no need to, it is unprofessional. It is better to let our system and sales do the talking for us. I feel the best talking is our consumer feedback.

I was just purely stating that our system is much lighter than stock. Now my personal opinion and what I have seen to date is that no other system makes the numbers ours does either. Until I see otherwise, this is what I know!

Thats all...

Thanks, Tony

I'll be honest with you, i've had a few people see my car and think the exhaust was stock, yeah the tips stick out a bit further, but as far as muffler size and location, it looks completely OEM. I also went to the dealership last night to see when they have some 40th anniversaries coming in and noticed the tips on the NISMO exhaust are WAYY larger.

I guess I mean that in direct comparison with the OEM exhaust, the Stillen looks dramatically different. However, I see your point that someone who has never seen a stock exhaust might think the Stillen was OEM. FI definitely has a 'tuner' look.

Exactly :)

stillen cbe is like 10 lbs heavier than stock. honestly, stock is already heavy enough. amuse titanium is 20 lbs lighter than stock. but it is so expensive! i would go F.I cf because i remember it is 16 lbs lighter than stock and so much cheaper than amuse!
the robispec single exhaust sheds at least about 40lbs with stock cats and downpipes

dont kno why the link didn show, ehh

don't know about any of that but my dad 10 lbs lighter then stillen and is fking awesome...

Fellas, you're all getting off track a bit, the OP wanted to know which exhausts made the most power and produced the best sound, now power wise, due to the370z.com members independent dyno sheets, the Stillen and FI exhausts produce the most power, its been proven. No one said anything about weight, now sound is subjective, but lets stay on topic please and not turn this into a pissing match about whose exhaust is better mmkay? Now when other members post dyno sheets with their HKS/Greddy/Berk/Invidia, etc. exhausts that make more power than the Stillen/FI exhausts, then the debate will be settled, but until then, fact is, Stillen/FI make the most power.

Making that decision
 

Ok, I've been a domestic muscle care owner for years this is my first import and I have experienced drone, especially under load. FI came out of the hole with a tremendous following but I wonder how much drone exists in the 2,000 to 2,500 rpm range. The majority of your cruising rpms live in this range. I don't plan on using HFC, will I need the resonators, and while X-pipes produce a little more power, H-pipes produce better sound. If I order a system from them next week, how long would I have to wait for it? The stock system is too soft, sound quality is my #1 priority.

Man, I hate drone. It drives you bloody mad and always seems to occur were you want it least while driving. Drone sucks!

None of the systems really suffer from drone, it seems the only ones that do are also coupled with HFC's. With my setup, it had a drone issue at first, but once the exhaust burned in, it quieted alot, and now there is zero drone to speak of. I hear the Invidia is the smoothest sounding, the FI/Stillen have more of a racey sound, and the Nismo is the quietest of the bunch. And i think Tony said that if you got on the list today, from build, to your door, wait is 5 weeks.

:icon18: Excellent timing, forgot about you guys!

Does anyone know whether BERKS did a Dyno on their CBE's?

Decision time
 

Invidia's system was all over Amazon and E-bay, Shops, distributors, and even small dealers selling for 839 and up. Question will any of the 350Z exhaust products work on the 370Z? there discounting is impressive. 5 weeks is about as long as I could wait, isn't Stillens system more expensive than FI?

Invidia has the best priced CBE out, and looks to be decent quality. Stillens and FI's are comparatively priced. I got mine for 1100.

I have 2 domestic muscle cars still to this day. That is what I was brought up with and what I love. I have also worked on Z's since they were a 280! You stated that you do not plan on changing the HFC's! I can tell you as long as you stay with the stock cats, our system will not drone. I have installed just about every variation that we sell so I have heard them all.

On a muscle car, H Pipes do produce a better sound but not on these Z's. Trust me, the exhaust note is not as smooth or refined when you build it with an H pipe. The bottom line is if you want quality come to us, we will take care of you. Quality and customer service is more important to us than anything else. We fabricate them in house to ensure every aspect of your investment gets handled correctly! Your system will make great power, sound great look great and fit correctly the first time! I have plenty of options to choose from and am willing to go over them with you. All you have to do is ask.

Please do not hesitate to contact me directly...

Thank you, Tony

I haven't seen a stillen dyno that shows stock + exhaust. Stillen weighs about 18 lbs more than stock from the weight reduction thread. FI is about 30 lbs lighter than stillen and imo looks best with the proven gains. I've had the FI exhaust and would definitely go back. The gains were shockingly noticeable and throttle response was drastically improved as well. I've heard the stillen in person and preferred FI. The quality of the FI exhaust is second to none as well.

ya here is a big way to go for tony he will build it and build it right and work with any needs you might have or want. Now if you guys would stop buying stuff from him so he can make the HFC's and exhaust for my FX50S that would be great.

^^rofl

I love the FI CBE, it looks great from the rear and sounds great too. But I dont have HFCs at this time and I have drone around the 2-3K rpm range. It bothers some and not others, Im getting used to it and will be getting HFCs soon so Im sure it may get worse but I got this car to for its performance and I guess noise comes with that. If I wanted quiet then I wouldnt have bought the Z.

:iagree:

Go with Fast Intentions :happydance:

End of this month or early next I should be confirming this. :tup:

Just hit me up when you are ready...

Thanks, Tony

And that is my only beef with the Stillen, which does appear to be well-designed and engineered. Unless there are reasons for the Stillen's heavier weight--pertaining to durability and reliability (valid issues, esp. important for the OP, who lives quite far away)--it makes no sense to me to ADD pounds with an aftermarket performance product. Maybe Stillen could answer? :iagree:

How about HKS exhaust?
is it that bad that no one is really talking about it?
I prefer FI over stillen for everything but how about HKS?
I am trying to decide betwwen HKS or FI
how long is it gonna take to get an FI as it is made by order?
I know the carbon fiber is for weight saving but what is the resonator for？
can anyone tell me what is the resonator for and how is it works?
is the resonator gonna help with power? or just making it louder?
sorry for so many questions.
Thanks.

this made my LOL, yeah 12-15 lbs is really gonna destroy your quarter mile time...

It uses larger mufflers, #1 for sound, #2 for the anti-fart can rice factor #3 looks close to OEM if you dont want the aggressive look.
