In all of your wise opinions, eventhough i've heard apex'i n1 is the best, and many ppl on here have claimed that it has added 50 hp or so,
I would seriously like to know which exaust system is the one true best system for the fc3s turbo. Im also planning on forgoing the catalyctic converter.
Its a nice meaty topic ; Apex'i N1, Greddy , Racing Beat, or other?

 

any canister type muffler will be the best optiion for power, but it seriously sacrafices the quietness. They are loud especially with no presilencer. But since you got a turbo, its more quiet then on a N/A with the same exhaust system.

No exhaust will increase by 50hp just like that. Correct me if im wrong but, the racing beat exhaust for the turbos also increase the boost, which is probably why that 50hp increase is alot from only an exhaust.

 

of course, i didnt say i believed them, 50 hp doesn't sound very logical, but i could be wrong.

 

not another one of these thread....


Apexi N1 Exhaust does not add 50hp, Apexi N1 is just a CBE (Cat Back Exhaust).
Greddy
HKS
Blitz and etc are mostly CBE and they taper down to a 2.5" or smaller at the cat.

Racing Beat offer both CBE and TBE(turbo back exhaust).
CS (CorkSPort) Also offer CBE and TBE option.

If you want something cheap, light, loud get CS exhaust. If you want something look kinda stock, have a deep throaty tone and willing to spend a lil more get an RB.

 

that is also my philosophy too...more boost=more hp

but i do believe that the racing beat exhaust is prob the best exhaust system for turbos. my opinion only.

 

racing beat ftw

 

dont forget all the supporting mod that goes along with it.

 

You should visit the racing beat website. Even they explain the reason in increased horsepower; less restricted exhaust means your boost can climb to around 10 psi on the stock turbo, so yeah you can get a 50 hp increase. Better not do that without fuel cut though or you'll be sorry... do more research.

 

If you get a fuel cut you will need to upgrade your injectors, fuel pump, and highly recommend you to port your wastegate (otherwise you will boost creep). Also some sort of EM for the larger injectors.

 

i have already researched, and have listened to opinions on this b4 ,but im just looking for further testimony and or opinions . as i already have installed a fuel cut defenser/defender which ever you feel like calling it., and im not looking for the cheapest, or loudest , im looking for a proper exaust system.and i am aware that they are cat-back, also i have already stated that i will be removing the cat later on when i choose an exaust system and supplementing it with a straight pipe. anyways i just want the general opinion of you all out there on which is the overall best exaust.
-thanks-

 

Fujitsubo? They basically give you a side to side comparison of HP/Torque and dB at a given rpm range between stock and their system for just about every car they make an exhaust for. Having heard an FC with a Fujitsubo I must say they sound freakin awesome as well.

 

The best setup is the RB full turbo system. It has a nice mellow sound and it very high quality. The 54 hp gains really are true, but as stated it is from added boost, which means you need to modify the fuel system to keep from killing the engine.

 

Also don't forget drive train losses. 50hp at the flywheel will only be around 43hp to the wheels.

 

Racing beat no hands down. Sounds like sex at WOT, and can be quite when you want it to be. It's extremely annoying if you had a loud exhaust on like corksport and cruising down the highway on a road trip.

I have the full turbo system, and boosting nicely at 6psi all stock with rb fuel cut controller, ported wastegate. Around 6k rpm it creeps to 8psi. Not to dangerous but not that great either.

 

man...do these threads ever stop?

Racing Beat Turbo Back

Ebay medori set up is the tittywampus. 280 dollars and sounds perfect (in my opinion), not city police's opinion though. It sounds good with silencers too.

The best exhaust is a custom system designed specifically for your application. Components are usually constructed from either 321 stainless steel or titanium, and the mufflers are often filled with lava rock. A good custom exhaust system will have proper hangars, good connectors like v-band clamps, slip joints, bellows (if needed), and dual type exhaust components will be cc'd for proper sizing.

 

i was looking for a titanium system, but the only thing i found was a universal by apex'i (only the muffler and stainless piping) assuming you have to have it mandrel bent . so far im hearing that most of you are for the racing beat application. as for how many times this type of thread is up, i dont really care, as i stated b4 and again i wanted everyones opinions. opinions change with the time and with the products. as newer **** comes out , someone might have something different to tell me that i dont know, im not arrogant to say i know everything hence why i ask. anyways the idea of a custom is intresting me though, i might end up doing that with a titanium exaust, or i might go with rb . but i thought since we rx7 owners have such great injectors from the start i dont think we have to change them, just up the duty cycle to probably 80 percent, i mean some of us have i think 550cc as stock injectors right?and they only operate at 65% stock settings . fuel rail, regulator and fuel pump sound like a good idea though, but to change the duty cycle , i suppose im going to have to have a proper computer, something along the lines of the power fc i suppose, but i'll hold off for that later. never heard of medori , so i will check that out as well.
thanks for all your input, its quite appreciated. and i'm not being sarcastic.

 

Just go buy the Racing Beat & be done with it forever - problem solved. Or else just hack your own stuff together and convince yourself its better than what a dedicated rotary supplier can come up with. I'm sure you would know exactly what setup will deliver the results you think you need and that everyone else is wrong or misguided. I would figure you would save negative $$$$ building your own titanium exhaust to someone else's specs because they said it was dope!

Greddy Power Extreme best sound and looks great!! I have CS downpipe and borla xr-1 presilencer into greddy power extreme catcack.

 

well i thought of titanium not because anyone told me it was dope, but because its lightweightness. and im trying to do things as proper as i can , im a patient guy. and i wont lie, haha im leaning towards rb, but im still open to suggestions, i dont think anyone is misguided, or wrong at all. well everyone also makes choices considering their situation and their own opinions.
and if someone is giving me sound testimony, then i cant really deniy it can i?

 

Exactly, so then get the RB turbo back.

 

agreed racing beat ftw.

 

i was looking at the RB turbo back, and i was wondering,....does the pre-silencer actually do anything? if not ,..i dont mind either way. but most likely im going with that one, since its all completely stainless from the turbo back, and it appears that it looks unrestrictive with no cat which is a plus.

 

I put in my vote for the RB too, I have the Fujitsubo Legalis R and its quiet and everything but the tip diameter is a bit big...
