jblackwell1 Posted July 23, 2011 Share Posted July 23, 2011 Will the headers from an sti or wrx work on our cars since the block configuration is the same? im looking to run headers with my new build but cant afford to buy them new with the prices ive seen. i dont see any here for sale and have pmd the one i did see with no response. So im wonder if any sti or wrx headers will fit ours and if so what year? Thanks for any help. Link to comment Share on other sites More sharing options...

jblackwell1 Posted July 23, 2011 Author Share Posted July 23, 2011 Really? i wasnt sure if the turbo location or something changed any thing, good to know Link to comment Share on other sites More sharing options...
jmorris6689 Posted July 23, 2011 Share Posted July 23, 2011 yea i was curious to this as well. Especially since i have a STi style turbo on mine, would i have to get a different up pipe to mount to the header? im using a greedy lgt up pipe as of now mated to stock lgt exhaust manifold. Also the part numbers on legacy headers differ from those on wrx's and STi's. Link to comment Share on other sites More sharing options...
TRSCobra Posted July 23, 2011 Share Posted July 23, 2011 Headers are all the same, up pipes are all the same. I have perrin wrx/sti headers and a turboxs wrx/sti UP on my LGT with a blouch sti style turbo. It all bolts up and fits fine, and i had the txs UP on with the LGT manifold and stock turbo.

fahr_side Posted July 24, 2011 Share Posted July 24, 2011 The stock items are not the same, but they do all fit. Over the years EGT sensors were added and then removed again, heatshields have been tweaked a little... small changes like that. The '04 and up STi manifolds are different and have larger diameter runners. They also bolt straight up. The STi crosspipes and up-pipes are exactly the same as uncatted WRX/LGT/FXT/OXT items so no gains to be had using those. The one situation where you have to be careful is using an equal-length header on an engine with the old style oil pan. The header will not fit until swap the oil pan to the newer style item. Obligatory '[URL="http://legacygt.com/forums/showthread.php/2008-gh8-238668.html?t=238668"]build thread[/URL]' Increased capacity to 2.7 liters, still turbo, but no longer need spark plugs.

Geo_08 Posted August 16, 2011 Share Posted August 16, 2011 So I have an idea that will replace my nearly rusted off exahust, but I want some feedback first. I have a 97 OBW limited and am replacing everything from the headers back. I am thinking of using these headers http://www.speedyracer.com/servlet/the-173/Subaru-Impreza-Header-for/Detail With everything from the catback from a 04 wrx. Besides lengthening do you foresee any problems, including emissions testing worries? Or flange mating issues? Link to comment Share on other sites More sharing options...
MDKSDMF Posted August 19, 2011 Share Posted August 19, 2011 grimmspeed pnp manifolds are a good option for a stockish exhaust manifold. Link to comment Share on other sites More sharing options...

grovlet Posted July 7, 2014 Share Posted July 7, 2014 I have Speedy Racer Headers wrapped in DEI Titanium Wrap on my 98 GT. No issues at all for the past year through snow/ice and rain in CT. Complete custom exhaust (including header and wrap) for $1K installed - how can you go wrong.... Link to comment Share on other sites More sharing options...
