i'm new at running true stock per NHRA. Can I run open headers or do I have to run through street exhaust?

Check is in the mail. Let us all know what your interpretation of the exhaust rules are..

EXHAUST SYSTEM
Optional. Adaptor plates, port plates, and header plates prohibited.
Pan evacuation systems prohibited. Turbo applications, aftermarket
header permitted – turbo must be located in engine compartment.
Mufflers and/or maximum decibel levels may be enforced at certain
facilities, according to any local ordinances that may be in effect.
Contact individual tracks for more information. See General
Regulations 1:3.

1:3 EXHAUST
All cars must be equipped with exhaust collectors, headers, or
stacks installed to direct exhaust out of car body to rear of car,
away from driver and fuel tank. Exhaust collectors/stacks must be
securely fastened (i.e., metal connector straps, bolted, welded,
etc.) to prevent loss of collector/stacks during competition. Flexible
tubing or “flex pipe” prohibited in all categories. If mufflers are
used, they must be securely attached to exhaust system and car
body or frame. Consistent with its endeavors to maintain drag
racing’s acceptance as a recognized sport and recreation, NHRA
is enforcing maximum decibel levels for Super Street, Super Gas,
and Super Comp vehicles competing at national events. NHRA

This is news to me, I did not know that NHRA had started a true stock class.

IHRA has the Pure Stock Class but NHRA ?

The rulebook pdf. file is 25MB.

I have not had success emailing this as of last night...I think we need a permanent thread here for a link to upload it from classracer.
