i will be picking up a catted erz dp soon from the fs section , i am also ordering.... gs crossover pipe-coated gs ebcs gaskets then i will get a uppipe , which i am thinking of a coated gs as well and in the spring i plan to have it installed and hopefully tuned on the same day if it works out that way (pms will be sent once i have all parts and funds for install/tune) ?s parts sound ok? if i go with a non flex uppipe , should i go for the perrin/hks , or get a cheapo non flex off ebay?.....i heard the larger diameter can hurt spool any thoughts / suggestions are welcome , thanks
GASKET/PORT/PIPE DIAMETER DOES MATTER. a good match is important. you want to be certain that the gasket is a good match for the up pipie, and that the up-pipe diameter is a good match for the turbine in-let side port. smooth flow for pre-turbo exhaust is important. otherwise you could loose power from the turbulance you create by mismatching pre turbo piping.
I'd just get the GS uppipe, the price isn't bad from what I remember, and it's local. The HKS is also a decent choice for a non-flex.
Because while flex section failures are rare, they happen. It's one less thing that can fail in your exhaust system.
when there is no flex joint in the exhaust it sure as hell can happen, just as likely as a flex failure.
whatever you get, wrap the uppipe and your inner CV joint boot will thank you. I couldn't beleive how much more weathered my passanger side looked then my driver side boot, all the heat just cooks the thing! Might as well wrap the dp too, why you getting a catted one anyways?
thanks , i will get a gs up then , i was a little worried about the flex failure thing or...... a great option if i can find it would be a sti uppipe...06-07 are not catted right? i will wrap it if i get a gs....any how to right ups for that ? the reason for a catted dp is i want to keep the noise down in my wagon , the one in the fs section is basically the same one i had planned on getting but with a cat...so i figured i would spend a little more , get one that has a cat , and help out someone who wants to sell
And 06+ wrx have catless uppipes. Just saw one posted here OEM 06 http://mnsubaru.com/forums/showthread.php?t=36770
so i picked up an 06 uppipe , a downpipe , and a gs ebcs what else do i need to get before i have it installed and tuned? i know i need...gaskets and vaccum lines and maybe wrap for the dp any thing else you could recommended for a stage 2 on a wrx? thanks
You'll be fine with what you have for now since the stock injectors will max out before the turbo does.
thanks , i just want to be sure i have all the misc. parts for the install , might get a pump and inj. right away as well
thats the plan , turbo anyway , but i was thinking next spring , so i may just wait and start getting parts along the way , thinking of a 68HTA for next year , but i think i would be better off doing the tranny work on my auto first
I had a year old megan racing uppipe flex section fail. There is even a photo some place on here of it. I replaced it with a Grimmspeed one.
might wanna talk to your tuner about that one. What if in a year or so you think that a 16/18g is too small. Makes sense to fit the injectors to the amount of fuel you will need when the time comes. +1. Might as well go to alibaba.com and buy from the source.
^ thanks , i will talk with him about it when i get it tuned , i think for now i will just do the parts i have and a tune , and come up with a plan for the future
