Or better yet fab me up a set of downpipes when you do yours
let me see how these come out and we can talk numbers ... materials are relatively inexpensive, my time is cheap ... the challenge will be fitment my car vs. yours ...

in reality, splitting hairs, it's a ~3.8" ID ... I wanted to do it once and for all...the 4" will be big enough for anything the car can put out!!

I've had months & months to think about it. I have a few good car buddies I bounce ideas off of, read what others have done, take the best of what comes out...some heated discussions for sure!

Id assume 3" is sufficient ... also get up underneath the car and see how much room is there...Also remember that the steering shaft is a factor.
pick up a copy of Maximum Boost by Corky Bell - it's a pretty good read and may help you with your build.
PM me about them ... I'll see if the guy has the template

Thank you for the compliment...Like everything you see on the internet(FB, IG, forums, etc.) you dont see what it took to get there, you dont see the scrap bin of it forked-out 3 times before it was finally done right. I'll be the first to admit that I'm not expert and quite possibly the best thing about these cars is there are always replacement parts and replacement materials. But with that being said - everyone was a beginner at some point in time.

thanks! glad the turned out...was worried when I left the guys shop I just dropped $120 on scrap...

If it doesnt have a bonafide function to make the car run, run safe, or run fast it has to go!
my goal is 2750lbs ... and it's getting real slim all the sudden...I'm somewhere north of 2900lbs right now
Found a pretty sweet fab shop in south denver who stocks a whole lot of aftermarket goodies...picked up $20 worth of 4" stainless...need a few slivers to mount V-bands to flex hose sections and want to 'attempt' a dual 3" to single 4" collector merge. Vibrant has one for $110 which looks decent but I'd like to try it myself first.
Got plenty of 3" 45* and now a chunk of 4" - mocked everything in CAD to conceptualize/see how the numbers fit first...took a 8" piece of 4" SS and 5lb sledged-it as gingerly as I could (according to my CAD drawing).
I wasnt able to use my band saw to cut my 3" merge section ... just had to guess & check with the 4" grinder...gaps could have come out better but it's close enough.
tacked everything together and looked decent ...
ran some welds tonight and not sure how I feel about them ... I'll sleep on it, if they bother me I'll grind them off and re-do them...
Fabbing up the Y pipe is sorta a time filler while coilovers come in...
I know (trust that) greddy did their best designing the filter-to-turbo track ... but GD it's dumb ... it fluctuates in size, sits right infront of the radiator, filters suck, among others...and I know, an OEM setup has to account for the alt/ac units...
luckily I have ample room to work. Been dreaming up ideas (feel free to chime in with ideas) on how make this as efficient as possible...The solution (from where I sit now) is to run 3" lines to an area of the engine bay that can supply cool / ambient air.
My thought is to re-do/relocate my cooling fan and run the intake pipes to the drivers side, fabricate a single airbox (utilizing a large panel filter rather than dual cone filters) that sits to side of the radiator that snorkels ambient air...
It's been in the works to relocate the oil cooler to the passenger side which will open up this area of the front end. The airbox will sit under the headlight in-front of the front drivers side wheel ... add some foil backed insulation and velocity stacks on the 3" pipes and I'll be set...
I removed all the a/c stuff from my car this time. I've also been thinking about redoing the turbo air intake pipes to gather colder air. The Greddy setup isn't the best. At idle with the fans on I can watch the iat's climb pretty high with the Haltech

Insult to injury when the charge pipe (right above the driver side header) is heating the air as well. I wrapped mine and temps dropped (per the haltech) but I have a feeling they'll drop a little more with the vents
coils came in ... and everyone in the land was happy
initial thoughts:
Packaged very well - everything wrapped & padded and doubled boxed using 2-ply cardboard boxes.
Fortune gives you a nice little packet with your spring dyno graphs, a hand-written certification, product instructions/warning/sticket/promotional brochure, spanners, and allen wrench. Just a nice touch.
Un wrapped everything and it looks good.
woke up at 8am on a saturday to get a start on this...the weather is still holding here in colo!
Fortunes installed ... put about 150 miles on them over the weekend...
my initial driving thoughts are they feel the same as the tokico/eibachs ... but I've been driving very very gingerly and not really pushing the car. I put the vehicle about 3/4" above the tires and it's too low ... scrapping on stuff. I'll probably put another 1/2" or 3/4" before I go and get the suspension (professionally) retuned.
I've set them 100% stiff which I'll lighten them up ... I did take a few corners pretty quick and no tire-rub - so that's good!!
on hard straight-line acceleration the back end would break-loose but the traction control would kick-in - the caveat should be the tires I have are horrrriiibbblllle...
here are some pics...pretty easy install and took 2 rounds of height adjustment to get it right.
Another perk, I dropped around 26lbs by doing this swap!
The lightweight/low output alternator and lightweight battery all did as expected for the time I put on the car. The hood louvers dissipated heat well (at stoplights I could see heat waves coming up) and no hot-start issues.
Im not 'completely' sure what greddy was thinking with their intake track (other than OEM constraints) but I put these 3" aluminum intake pipes w/the greddy filters and it 'felt' like the car was peppy'r and I audible hear the turbos whine (where before I couldnt).
I'll be pecking away at the exhaust ... added a 2" piece between the flex hose and a V-band flange - which will mate up to the 4" aluminum exhaust.
waiting on some 16ga aluminum sheet to fab-up the airbox...came across this article(mostly on page 2) - seems well written but it's hard for me to follow his logic but the author mentions the importance of taking the intake charge from ambient air (as opposed from behind the radiator...Greddy)...speaks of an 8% loss when taking charge air from behind the radiator...
wanted to weld a little bit last night...got a flange and a piece of 4" welded on, tacked the two 3" sticks. I think these will end up getting trimmed back but this will work for now!
I'm interested in the effects of an ambient air intake temp vesus 'behind radiator' air intake temp. I have a ton of data logs where I can compare the two different intake sources...
Random question
Are you running map or stock maf?
I got Haltech ecu with 4 bar map sensor and comes with no instructions on how to connect the map sensor :/

ripped that MAF a-lonnnnnnnngggggg time ago!!!
let me look at some stuff...I got a link on my computer with the assigned harnesses
My setup is similar to the greddy kit as you've seen. 3" intakes were quite a tight fit. And I ditched the a.c. so that helped. I did have to bend the power steering feed tube to clear the passenger intake.

I ran power steering-less (kept the pump, but removed the belt) and I didnt mind it and dropping down the mini-alt really opened things up...
I've got some 16g aluminum sheet coming in later in the week where I'll fab up a airbox that'll sit on the driver side under the headlight.
Hoping this will drop my IATs ... I'll compare & contrast...
