The PFC has a built-in boost controller right, so the Greddy boost controller you have under the stereo is waiting to be removed? Please correct me if I'm wrong. Just curious because I've been wanting to pick up a PFC for a WHILE now.

 

You are wrong

Yes, it is an option. But you have to buy the additional kit, its not built in.
Not many people use this, as a standard boostcontroller is easier to use, sometimes cheaper and something like a avcr works a whole lot better

 

Nice, I always wanted duals but don't really think my pocket can afford a 4.5" downpipe to a 4" y-pipe to two more 4" pipes with a muffler on each hah.
Good choice on the ecu, I would have done the same if I had a TII wiring harness.

On a side note, wouldn't it be funny if guys made videos like a girl?

silly question is the RB exhaust a full stainless system? the site doesn't specify.

 

Yes

 

No it's not built in. :P


I would actually really like to see someone do that. hahahahaahha

Yes its stainless steel.

 

glad to see you still have the FC bl00dlust, love the Apex'i N1 dual exhaust

 

yeah that exhaust does sound awesome.. i think im going get me a single out..

 

if i may ask a question?? idk how well the apexi n1 dual is in terms of performance, so i thought about buying the RB DP Pre silencer and y pipe and connect it to n1 dual... what do you guys think? and where would i be able to find just the n1 dual mufflers without paying 800 just for one lol?

 

buy the whole RB system
/discussion

 

not a big fan of the mufflers which is why i asked lol

 

at least from the ones ive heard.,..

 

OP needs to marry me, lol. Sexy, good taste, mechanically inclined, and owns a 7; sold. haha.

In all seriousness good job, sounds great, always thought N1 duals would be a bit too loud, but it doesn't seem too bad.

 

I currently have the RB and have to say that the Apexi is a better option as if you are turbo (or plan on being) you will need to upgrade to an exhaust that is more free flowing (I.E. wider diameter). The RB is quality and sounds decent, but will need to be swapped eventually. Even though I plan on staying NA for now, I am looking to get an PFC to make the most out of what I can.

 

RB is 3" to the Y which has two 2.5" pipes, and there are numerous cars with 400+ HP using this system. I somehow really doubt you, or 95% of the people on the forum will exceed its limitations...

Edit: Add citation, just found 550 HP from Jrat on RB Rev II..

nah Houston is definitely right, the RB exhaust from size is one of the best out there.. if im not mistaken the apex pipes go from 2.56in into HUGE muffler canisters that are 4.53 in's... i just want the mufflers cause i love the sound but i want to match it with the RB system... Anyone know where i can get the mufflers for a decent price??

 

I apologize for my post, I was under the impression that something like a 3" diameter would be more beneficial on a turbo 7.

 

the RB rev II is 3in... u sure ur talking about the same one since they do make multiple exhausts?

 

the RB is not 3" all the way back.

 

yeah its only 3inchs till the y pipe exit, then its like 2.5 right?

but if im not mistaken, isnt the apexi dual 2.56 the whole way into 4.56 in muffler canisters??

 

2.375-inch on the RB
and idk about the Apexi, some people like it, its just too cannon like for me

 

Apexi, looks real good sounds even better

 

so can someone tell me the diameter on the apexi n1 dual pipes?? especially the DP?... becausei m purchasing a exhaust in about a month and i love the way the n1 sounds.. let me know

 

Where do you buy the n1 dual? Everywhere I look the picture is of the baby n1 twin mufflers that only exit out the drivers side. Thanks in advance.
