I need a 3in dp for a 2g gst

[dsm4fun]

Hey does anybody know where i can get a full 3in downpipe for my 2g fwd. I have been searching and everything starts at 2.5in and expands to 3in. Another thing is i need the downpipe to keep the cat converter because I live in california. If anyone could help i would appreciate it.

Sorry, but that one starts out as at 2-1/2" also, then "steps-out" to 3". I don't recall seeing a DP that starts out as a true 3". Most tubular O2 housings are 2-1/2".

You might end up having to get one made if you really need it to be 3" all the way.

Thanks for the link kevin but they only carry 2.5in for fwd at buschur but im checking into the hahn racecraft one. And jim thanks for your input as well.

And that's going to be your problem......most start out at 2-1/2" then step/flare out to 3" before the bend.

What did you go with on your car?

I actually run the HAHN Super16 with their 2-1/2" O2 housing and 3" Eliminator jr. down-pipe, 3" HF cat with a modded 3" Thermal cat back.

The HAHN 3" DP starts out at 2-1/2" then TAPERS (not steps) out to 3" in about 4-6". After looking at different designs I went with the HAHN unit as the taper offers less turbulence than the step versions that are commonly available.

The other thing I liked about the HAHN unit (DP + HF cat) is that it's actually 6" longer than the OEM setup which gives you the extra length needed to cut off the "step" portion on cat-backs.
