That's what I did on my 92' SHO, true dual 2.25", I bet I could do it on this car too. Come off the header with flex pipe, used that on my SHO too, and use an appropriate "Y" fitting and run the pipes on top of one another to the back and then split into two, 2.25" racing mufflers like this: http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_x_16120050-P_x_x?cm_mmc=ACQ-_-Google-_-enhancedRM-_-16120050&ci_src=17588969&ci_sku=16120050&ci_gpa=pla&ci_kw={keyword}&gclid=CJ-igbDn_LUCFe4-Mgod4QwA3A

this seems like a awesome mod but 25 pages of reading and still not sure what i need...


can someone sum this up?

Here's Matt's (TORQUERULES) list:

OBX stainless Duratec header
2 flex pipes
Secondary O2 sensor CEL eliminator
O2 sensor bung for secondary sensor in flex pipe
Gaskets
Heat material to cover any close lines and wires
Primary wideband sensor with longer harness to replace stock primary

I recommend to use the factory manifold gasket. The one sent with the header is not great quality. Make sure you install the flex pipe the correct way or it hit the subframe.

Exactly. The factory Gasket is more then adequate for the job.

I added custom subframe exhaust mounts to solve the clearance issue on the flexpipe. Besides that I added 1" of pipe down the road to bring the dual exhaust back to the desired location.

Do you have a pic of your custom sub mount?

I second that, mines hitting alot under hard acceleration

Is the sensor eliminator required? Also, what size are the bungs? I have ordered my obx header but I need to know what else I will have to have to install.

Exactly what you need. It allows you to pass OBD Emissions testing.

I wish there were a way to separate the banks for a true dual set up instead of a 4>1. Be nice to have 4>2>1, a Tri Y header.
