3" fwd 2g downpipe.

[babyviper]

Does anyone sell a 3" fwd downpipe, if so where can I get one?
BTW: I don't want a 2.5 to 3" transition after the flex-pipe, and I also have a two bolt flange.

Here's a good place to start looking. DSM Downpipes - DSMtuners.com

I have a Hahn Eliminator downpipe (not the Jr. version) with their tubular O2 housing. 3", no neck down anywhere. Very nice, but pricey piece.

Are they for 3-bolt o2 housings or your average 2-bolt.

my Stillen race pipe is 3" as far as i know. but it does eliminate the catalytic converter. but it is 2 bolt pattern to bolt up to the oem or aftermarket 2bolt 02 housing.

I use one made Megan Racing. You can also check ebay, you'll find lots of them.

As i said in the title I don't want a downpipe that is 2.5 from the o2 housing to the flex.

Never heard of a stillen downpipe for 2g eclipses, do you have a link?

Ok, I'll be the one to ask.

Why MUST you have a true 3" dp? Having the first section 2.5" shouldn't make any difference for you.

Our DPs have a 2 1/2" stainless steel first bend with a 2 1/2" stainless steel flex section. They then expand to 3" right after the flex section right under the oil pan area. Why start out at 2 1/2"? If you are running on the stock O2 sensor housing, even ported it is 2 1/2" inside diameter. When the exhaust gasses are hot, they flow better, 2 1/2" is plenty for the first 12". As the gasses cool , bigger helps. By going to 3" after the flex section, we allow this expansion and also allow for better clearance at the front where room is tight.

Then I would say to check out Road Race Engineering as mentioned above.

The reason I want to go full 3 inch is because I have a 60-trim and plan on maxing it out. I think that 2.5 will be a restriction.

They are 2.5" at the o2 housing for about 2 inches if that then they go full 3.

You must be refering to the 2g gsx downpipe because my buddy has one, I have had the megan racing fwd 2g dowpipe and the now I have the apex-i unit neither one are like you described. If the 2g awd wil work with my fwd I will use that.
