Are test pipes allowed for BSP? The way I read the rules below, they are...but I'm hearing that they're not...I can see it from both sides - anyone know for sure?

2006 SCCA rulebook:
"
15. STREET PREPARED CATEGORY

15.10 ENGINE AND DRIVE TRAIN
E. Emission control devices may be modified or removed. This
permits the oil filler cap to be modified or substituted, but does
not allow valve covers or cam covers to be altered to install a
breather or for any other purpose.

H. Exhaust manifolds and muffler systems are free, except that they
must be quiet and terminate behind the driver."

First off, don't take what I say as gospel as every time I think I understand a rule, somebody points out an exception or different interpretation.

My guess is you can't remove cats. The intro section to Street Prepared starts off with :

STREET PREPARED CATEGORY
Cars running in Street Prepared Category must have been series
produced with normal road touring equipment, capable of being
licensed for normal road use in the United States, and normally sold
and delivered through the manufacturer’s retail sales outlets in the
United States.

and ends with the last paragraph:

The SCCA does not encourage or
condone the breaking of laws governing pollution control systems or
the alteration of street-driven vehicles contrary to state and federal
laws regarding their use. It continues to be the responsibility of the
individual to comply with such state and federal laws.

In the first paragraph, it contains the statement "capable of being
licensed for normal road use in the United States". If you remove the cats, you're no longer street legal. The last paragraph is pretty self explanatory.

I think you have to go into the Street Modified or Prepared classes to use TPs.

 

Yes you can. The entire exhaust system is free from 1" inside the exhaust port on the head to the tip of the tailpipe.

The above paragraph is generally intepreted as referring to the eligibility of a particular car for classification in the SP category, not to individual vehicle preparation.

This is a legal CYA and is not in reference to any individual vehicle preparation. Most national level SP cars are trailer queens and are far removed from "street legal."

 

yeah u can, i had a test pipe in my rx8 running bsp

 

"While the rules of the Street Prepared Category have remained
essentially the same, the laws governing various aspects of streetdriven
vehicles have changed over time. The original concept of this
category as made up predominantly of street-driven vehicles has
been rendered inappropriate. The SCCA does not encourage or
condone the breaking of laws governing pollution control systems or
the alteration of street-driven vehicles contrary to state and federal
laws regarding their use. It continues to be the responsibility of the
individual to comply with such state and federal laws."

I agree that it sounds like TP's are legal.
