Since CircaX's downpipe is on backorder, are there any other alternatives? i don't trust the ebay one, so does anyone else know where i can get a downpipe from?

I wouldnt buy from him, I emailed him SEVERAL times and never got any help at all.... I have the random tech cat/downpipe, but havent installed it yet. I would suggest that since you get to keep both o2 sensors.

Try ebay, I have seen SS downpipes for our car for like $150.

i have the hks-a ss downpipe, its got 2 holes for both o2 sensors... and its a major improvement from just replacing that pipe!!! its well worth the $150

wannabefast: is your car excessively loud now with that downpipe?

is the thicker tubing on the downpipe a large resonator? ... or is it just straight all the way through ?

but the one on ebay has a "high flow cat" all ready welded on.. i'm all ready getting a "real" high flow cat, so i just need the pipe... any ideas?

well its sounds like crap right now, but im gonna give it a while before it burns out the excess packing in the high flow cat, my piping is straight from the cat to the muffler, no resonator, and the wider tubing on the downpipe is a high flow cat so far the check engine light turned on once, but i reset my FI ECU and its fine right now but second gear is NOTICEABLY faster

as for the piping on the downpipe, you can see straight through it... so i dont know if that really affects anything

Does anyone have a picture of the "fat downpipe?"

it's not a fat downpipe ... it's just a resonator welded onto the downpipe

oh.. im testing my homemade o2 simulator right now and if it works correctly, i will make a few more im still in the testing phase, but i think it will work like i want it to

with the downpipe, do u need an o2 simulator? and when u get a highflow cat do u need a simulator as well? is that legal?

if it has 2 holes for senors then no simulator should be needed.
