Not sure yet CB if I need anything more-have to start putting ting aside for the child.Due in Nov.
Im adding a resonator to cut the noise.But I still looking at the FMIC and Crank pulley but again Im pretty happy once I tune.
so It would really be a cost benefit issue. SO probably the crank pulley would be a easy add on
Any comments??

I might add another resonator to tone down the volume a little.
I will be tuning on the dyno soon so will let you know the results

| Farley is a Exhaust Master Blaster! Excellent workmanship! He did my downpipe as well, and I installed a 3" XO2 catback......TOTALLY different car |

| Flex030, u think it wud be better to do the entire turbo back by farley or go aftermarket catback and let farley do the downpipe alone? |

Well I think it's a matter of choice and your pocket size I.M.O.
Your entire exhaust system is very important hands down but if I had to compare a turbo back or catback to a DP I would say your DP is just as or even more important. (I prefer a turbo back than a catback btw).
You see the most important thing with a down pipe is to minimize turbulence as much as possible at the turbo outlet when the waste gate opens; same goes for any exhaust system. In some aftermarket DP brands you would see a bell mouth, bell mouth with a splitter plate or two separate pipes. (Stock Legacy is a 2 ½” hole with a flat plate forcing the waste gate air to hit a wall causing a 90 degree turn and plenty turbulence).
I choose Mr. Farley because of his years of experience and quality of work.
His work is just as good as most aftermarket brands and cost effective for similar performance gains. (I am aware that some A.M brands are tuned).
So to answer your questions if you like brands and could afford it get the whole system aftermarket.
If you want to be economical I recommend you do your entire exhausts by Mr. Farley for similar gains and for a lot less; again it comes back to your tuner to a certain extent in terms of gains.
In the same breath if you have the money you could buy an aftermarket DP and let Farley do the rest but I would not do it the other way around if I had a choice between going A.M turbo back or DP, again because of the importance of the DP.
Basically the rest of your exhaust i.e. mid pipe, turbo back, barrels should be as straight as possible with minimum bends/kinks and a free flow barrel as to reduce turbulence hence resulting in a free flow; not too free though there must be some resistance present.
Go with a 3" DP then 3" pipe all the way to the "Y" intersection then bring it down to two 2 1/2" pipe into two 2 1/2" free flow barrels. Mr. Farley custom builds these as well, full stainless outside and the core...

I don't think this is true.
In ALL exhausts you want to maximise the velocity of the exhaust gases.
In a turbo application there is already a "restriction" caused by the turbo unit itself. You simply want to have as little turbulence as possible, that's where the down pipe comes in, it's best to have a dp with smoothe transitional bends but not always this is possible due to the engine bay dimension and turbo location.
The first 2-3 ft. of exhaust after the turbo is most important to maintain that velocity that I first described, after that the bigger is usually better rule applies i.e. cat-back.
Anyone feel free to correct me if I'm wrong because I'm here to learn too. |

^Correct...but just to expand on your point....
...in an N/A car, you want to maximise exhaust scavenging (hence the limitation in pipe diameter depending on cc of the engine).
...in an F/I car, you want to encourage high volumetric flow of gases through the turbine, so technically, a bigger diameter cannot really hurt (up until the point were you start to get cylinder "blowthru" of combustion gases). |

^^^^ Ok guys fair enough thanks...
BUT!!!!!
I was just looking at it from the point of view where a STi owner had a 4" system on his car and he lost a vast amount of power not until he went back to a 3" system he re-gained some power.
From this stand point I made that statement maybe I should of been more specific when I said that ... |

Man, we're all learning. Some people forget that on 2NR.
BTW, was it 4" from the turbo-back or was it from cat-back? |

Thanks Flex030, pretty detailed answer there
I see CB posted a link to a catback tho...so if i were to get sumthing like that, plus an after market downpipe and take it to Farley,would that be a good option ? The price of the XO2 Catback is pretty good...how would Farley's price for a catback compare with that?
Im also concerned about buying an AM DP and it not fitting properly...i tink i heard copper having some issues like that....thats why i was leaning towards a Farley DP instead...but i wud have really liked an AM one  |

Conrad, I'm not sure buddy I just saw the exhaust pieces on the ground, I did not ask the guy but I assume it was the entire exhaust from what I saw on the floor minus the DP. It looked real huge and funny.
Hence the reason stated why he told me he was changing it to 3" |

No probs buddy, being enthusiastic to share info is always an excellent learning practice for everyone.
Price you have to discuss that with him, compare and do the math.
The DP (USA) is not a prob you could have it removed and a JDM plate tig welded no biggy... |
