Nameless Performance Equal Length Stepped Header

Jason, um... How do you think it'll be w/ overpipe, HF cat & your latest offset system @ cruise?
My older-guy ears are getting cranky to noise. lol

I'm more concerned abt mid-range TQ as well.

Thx

Again, all of my 'omg it's so loud' comments are in reference to the full 3" system. It should be pretty reasonable with a 2.5" system. And I'm not a bit concerned about this header producing great midrange and high end gains.

In Massachusetts? Easy. Which entity does your smog checks? Let me know and I'll straight up call them to figure out what we need to do to comply. In the Democratic Peoples Republic of Kalifornia, lololol...nochance.

What's the diameter of the original one-piece OP/DP?

lol basically needs a cat and to pass the OBD test without disabling sensors. I just want a nice catted header that makes good power and flows nice. Bonus if it works well with a SC as I'm leaning toward that route.

You have a chance!!!

Installers may not install a new aftermarket catalytic converter in a vehicle unless all of the following conditions are met:
(A) The vehicle is specifically included in the vehicle application list for which the
new aftermarket catalytic converter has been exempted;
(B) The vehicle is more than 7 years old or has more than 70,000 miles on itsodometer;
(C) The vehicle is beyond the coverage of the OEM catalyst warranty period(which can vary from 7 years or 70,000 miles to as high as 15 years or 150,000 miles).2 Installers may reference the vehicle owner’s
manual/warranty booklet or contact the vehicle manufacturer or its
representative to verify the applicable OEM catalyst warranty;
(D) The vehicle has a legitimate need for replacement of the existing converter that has been established and documented by the installer on the repair invoice. If the OEM converter is present, the installer must make a determination that it is not functioning properly before acting to replace it;
(E) The exempted new aftermarket catalytic converter is installed in the same location as the OEM catalytic converter it is designed to replace. The front face of the installed catalytic converter shall be no more than three inches further upstream or downstream in the exhaust from where the front face of the OEM catalytic converter was located. The installation may not alter the location, position, or orientation of oxygen sensors upstream and downstream of the catalytic converter(s);
(F) The exempted new aftermarket catalytic converter is installed on a one-forone catalytic converter (not substrate) basis;
(G) The exempted new aftermarket catalytic converter is installed with all other required catalytic converters (no consolidation of catalytic converters, nor addition of extra catalytic converters is allowed); and
(H) A warranty card has been filled out by the installer, signed by the customer, attached to the repair invoice, and a copy returned to the manufacturer.

We just gotta tack on a buncha miles and limit the design of the header!

Actually, on second thought, it probably wouldnt work. I already have an SRT headerback exhaust. So the chances of getting a stock fitting aftermarket header with a cat are slim to none :-/

All I'd like is a full exhaust from nameless. Catted UEL header, 2.5" all the way back and a bit louder than stock but just enough to hear the subbie rumble under accel, doesn't need to be crazy loud.

Can't wait for you guys to finally release your headers

I don't think Nameless will be doing a UEL since it is just for sound. They're sticking with their EL longtube design for maximum performance last I saw Jason talk about a UEL.

I'm pretty sure the majority of headers exits at the stock position for maximum marketability (more exhaust/header combos)

Yea, but they make most of their gains from removing the cat.

You can still have catless headers with the same spot for the pipes ...

I understand that, my point is a majority of them are catless and I don't want catless. I'm tired of having to hunt around for an inspection sticker.

Those look like Federal emissions requirements, not state-specific. I could be wrong, but I don't feel like searching. For me to pass emissions...they need to visually check under the car for the cat (there's one in the DP that they'll see) and then just do ODBII scan. I can get away with a tune that turns off the CEL.
