I wouldn't be the guinea pig. The old adage, you get what you pay for is always true, up to a point. I'm scared of Ebay crap, but who knows, it might work fine.

I think that the cheapest I'd go is the Helix stuff. $450 for a up/dp from www.gruppe-s.com with CEL fixes, and you already know that hundreds or thousands of WRX's are running that.

 

I would only go with helix. That flex joint stuff worries me!

 

Helix also has a flex joint but I wouldnt worry about it.

 

.... helix is flex joint

unless you mean the flex joint in the ebay uppipe in the above mentioned post.

i say go with helix, i did, just like thousands of others :P

 

My bad.

 

do a search here and on clubwrx for "erz". there are several write-ups. I haven't seen anything bad said about them yet. they seem to work just fine....no fitment problems, no leaks (assuming you instally it right), and expected power gains. the only drawback is the DP eliminates both cats. if that's not what you want then this isn't the pipe for you. You can probably get a muffler shop to cut it and weld a flange on it so you can use it with the stock cat and STILL pay less than most uppipes or downpipes alone.

you get what you pay for....but if you pay more than what you want is worth you're just an idiot ...its just a bunch of piping.

I just ordered the flex uppipe for $101 after S&H/tax.

I will let everyone know how it does in my all stock but wheels, wagon!
I will include pics and measurments if possible.

 

i dont know why its polished. but i would paint the down pipe incase you ever get poped and have to open the hood

 

uhmm, would it be against the law though? I still have my DP cat and stock exhaust.
I thought that the STi had a straight through uppipe as well?

 

If your car came with a cat in the UP (which it did) then removing said cat IS illegal. The STi was designed to pass smog without that cat (through the use of variable valve timing etc.) so theirs is legit.

I always believe in the saying "you get what you pay for"

 

there's a HUGE thread on this set of pipes on clubwrx.net. Everybody's pretty happy with this combo. Personally I decided to get the PDE uppipe (because of the mounting hardware for the lower heatshield) and a Helix Catted DP (because I'm in CA and I like passing SMOG) but I'd say the feedback on these things is coming about 90%+ positive. You may get a few more HP and TQ out of "Better" brand-name parts, but if your chouce if your choice is cheap parts like this or nothing at all, they're not bad at all....no fitment problems, no quality control issues.
