karlxmas Posted April 2, 2007 Share Posted April 2, 2007 You might as well do them both at the same time, that way you can knock two birds out with one stone. I have done the downpipe and im fixing to do the uppipe, but i wish i would have went with both at the same time. Link to comment Share on other sites More sharing options...
whobaru Posted April 3, 2007 Share Posted April 3, 2007 Exactly where are the cats on this car? Link to comment Share on other sites More sharing options...
ShockerGT Posted April 3, 2007 Share Posted April 3, 2007 Exactly where are the cats on this car? 3 cats total for 05/06 - 1 in UP, 1 in DP and 1 in midpipe 2 cats in 07 - 1 in DP and 1 in midpipe Link to comment Share on other sites More sharing options...
whobaru Posted April 7, 2007 Share Posted April 7, 2007 Awesome, thanks! Another question if I may...I'm seriously considering gutting the stock UP, DP, and mid so I can pass the visual smog inspection. Is there a significant performance difference between doing this and getting cobb stuff? If so, any suggestions on how to get around smog? Also, I keep reading a lot about leaving at least one cat. Why might I do that? Will I not pass the sniff test if I remove all three? Do people install cobb pipes, then put stock back in for tests? Okay, enough questions.

frathouse87 Posted April 19, 2007 Share Posted April 19, 2007 I would have to disagree with your stage definitions, not to say "NO WAY YOUR DEFINITIONS ARE CRAP!" But rather to say well what do you think of how I put it STAGE 0: Nothing or panel/cone filter STAGE 1: At least Stg 1 Tune, plus Stg 0 STAGE 2: Stg 2 Tune + DP STAGE 2.5: Tune + TBE + Headers/UP + Panel/Cone filter STAGE 3+: Start into intercoolers and upgraded turbos I just think it makes more sense because it goes more into what the manufacturers say what a stage 2 is...tune and DP...no intercoolers or anything...Just a thought Zac Link to comment Share on other sites More sharing options...
wukindada Posted April 20, 2007 Share Posted April 20, 2007 You must have a DP to go to stage II though...... Toyota 6EATS .........SUCK!!!!!! Link to comment Share on other sites More sharing options...

tdli Posted May 24, 2007 Share Posted May 24, 2007 what is the expected awhp range for each of the stages? STAGE 0: Nothing or panel/cone filter STAGE 1: At least Stg 1 Tune, plus Stg 0 STAGE 2: Stg 2 Tune + DP STAGE 2.5: Tune + TBE + Headers/UP + Panel/Cone filter STAGE 3+: Start into intercoolers and upgraded turbos thanks!

hutru01 Posted May 24, 2007 Share Posted May 24, 2007 STAGE 0: Nothing or panel/cone filter (250 crank hp, 190 wheel hp) STAGE 1: At least Stg 1 Tune, plus Stg 0. (290 crank hp, 220 wheel hp) STAGE 2: Stg 2 Tune + DP. (300 crank hp, 230 wheel hp) (way more torque than Stage 1 though STAGE 2.5: Tune + TBE + Headers/UP + Panel/Cone filter. (320-350 crank hp, 250-280 wheel hp) (depending on your mods) STAGE 3+: Start into intercoolers and upgraded turbos. (375-400+ crank hp, 300+ wheel hp) These numbers are approximate.

whobaru Posted May 24, 2007 Share Posted May 24, 2007 Okay, noob question...When someone on the street says, "I have X horspower", do they mean at the crank or at the wheels? And does awhp mean "at the wheel horsepower" and awtq is "at the wheels torque? I just want to make sure I've got this right and know what I'm talking about.

tdli Posted May 24, 2007 Share Posted May 24, 2007 awhp means all wheel horsepower. rwhp means rear wheel horsepower. usually people just use hp which means the hp engine crank produces; and this number is before the drivetrain power lost. awhp and rwhp is after drivetrain power lost.

hutru01 Posted May 24, 2007 Share Posted May 24, 2007 ^ awhp means all wheel horse power Most of the time, people on the street refer to their horsepower as crank horsepower. Unless they specifically say, "My car dyno'd at XXX to the wheels", they most likely don't really know and are going by factory estimates. Link to comment Share on other sites More sharing options...
whobaru Posted May 24, 2007 Share Posted May 24, 2007 oic! Thanks tdli and hutru01! One subesequent question then if I may. Do some/most/all dynos have all four wheels on rollers and regardless of your drivetrain they read the total power? Seems like all they dyno videos I've seen have just two wheels on rollers. Maybe I just need to look closer. I don't have time right now. Link to comment Share on other sites More sharing options...
tdli Posted May 24, 2007 Share Posted May 24, 2007 most of the dynos i have seen are with 2 rollers, meaning for front wheel drive or rear wheel drive cars only. i am sure there are dynos with 4 rollers. you can still dyno an all-wheel drive car on a 2 roller dyno though, just remove the drive shaft and now its a 2 wheel drive car.

That's what I assumed they'd have to do. I wonder if dynoing an AWD car with the drive shaft removed is as accurate as testing one with four rollers and all wheels driving. I bet a two-roller machine would be more generous, but not much. Maybe a couple ponys. Link to comment Share on other sites More sharing options...
qikslvr Posted May 25, 2007 Share Posted May 25, 2007 Here is a link to mustang dyno products. http://www.mustangdyne.com/performancetuning.htm You should really only have your subaru tested on an AWD dyno. It is stated right in the owners manual. I'm in the dead center of the U.S. and I have to go to Minneapolis, Cleaveland or Salt Lake City to hit an AWD dyno. Let's kick this pig!

I'm about five hours from Salt Lake (Boise, ID) so not too bad. I plan on dynoing after I hit stage 2.5. Thanks for the info.! I'll be sure to wait for an AWD one .

kscottw Posted May 28, 2007 Share Posted May 28, 2007 What is it considered then with the ecu upgrade and just a catback exhaust with no UP or DP? Link to comment Share on other sites More sharing options...
hutru01 Posted May 28, 2007 Share Posted May 28, 2007 ^ That would be considered Stage 1.5 I think Link to comment Share on other sites More sharing options...
jmfspecb Posted July 23, 2007 Share Posted July 23, 2007 Kind of off topice, but not entirely.... Has anyone thought of what mods would give rise to a legit claim to an "STI" badged USDM Legacy? Link to comment Share on other sites More sharing options...
hutru01 Posted July 23, 2007 Share Posted July 23, 2007 ^ All STI products....STI Intake, STI exhaust, STI uppipe, STI Turbo VF 39, FMIC, STI STS.....but thats just my opinion I personally wouldn't refer to my Legacy as an STI simply because I have mostly Cobb products The only thing STI that I have is the STS.

strife1012 Posted July 23, 2007 Share Posted July 23, 2007 I would say it would have to have all the same as the Impreza STI, or the Liberty STI. Hell the Liberty STI is more STI than the Impreza Link to comment Share on other sites More sharing options...
WombatGT Posted August 7, 2007 Share Posted August 7, 2007 Ok, where would an STi swap place on the stage level? W/ DP and tune? Working on figuring out where I am. Got a used LGT and got a surprise under the hood. Thanks, Link to comment Share on other sites More sharing options...
hutru01 Posted August 7, 2007 Share Posted August 7, 2007 ^ You sure lucked out. The VF39 turbo can push 300 to the wheels with the right parts and tune. Link to comment Share on other sites More sharing options...
