96 GS exhaust return to stock

[Phil H.]

A previous owner of my 96 GS had aftermarket exhaust installed on the car. I'm new to NCRS and have yet to experience having a car judged. My question is, points wise, would it be better to just leave the aftermarket system on the car, or, try and find a good salvage system in an attempt to put it back to "original"? Thanks for your help!

Welcome to NCRS Tech Board.

Top of this page is a header line with "HOME" "JOIN" "SERVICES' etc. When you click on SERVICES, you'll get a drop-down menu. One choice on this drop-down menu is "Judging Awards". Click on Judging Awards and "Judging Score Sheets" becomes an option. This option opens up pdf sample copies of our judging sheets - download what you need.

In your case, points associated with "Exhaust" will be found under "Chassis". Two columns, "Originality" and "Condition" have associated points.

If, as described, your current aftermarket exhaust is "significantly dissimilar" to a stock exhaust, then a 100% deduction for Originality would be assessed. 100% Originality deduction also generates a 100% Condition deduction. This is worse case of 16 Originality and 15 Condition points lost if only mufflers and exhaust tips have been changed. (Cat-Back changes would generate addition point loss, etc. )

There are 4500 points total in Flight Judging. You can loose 270 points and still get Top Flight.

Replacement exhaust would be subject to potential deductions for Configuration, Date, Completeness, Installation, and Finish. For example, muffler dates would generate a 20% deduction for Originality (3 points). Condition is now judged separately.

As stated before, this issue alone would not keep a car from Top Flight. Some owners take a point hit just because they like the sound (noise).

Your decision, you need to consider cost and enjoyment.

Re: 96 GS exhaust return to stock

Thanks Dave! That's just what I was looking for. I'm going to keep the aftermarket exhaust. I'm thinking that with the originality and condition of the rest of car, losing 31 points won't keep me out of Top Flight. Another newbie question, just out of curiosity, if the aftermarket exhaust is judged not to be significantly dissimilar, is it possible that I could keep some of the exhaust points?

Certainly possible to keep some of the points. A copy of, our new 9th edition, Judging Reference Manual (JRM) will be a great help to you. Available from NCRS Store at link below. Our year specific, Technical Information Manual and Judging Guides (TIMJG) tell you "What to Judge". While the JRM tells you "How to Judge".

https://www.ncrs.org/shop/index.php?main_page=index&cPath=1_69

JRM Section 4 covers Standard Deduction Guidelines (SDG). Some Standard Deduction Guidelines specify HOW to judge items common to all Corvettes. Items like Engine Blocks, Wind Shields, Batteries, Tires, etc. Those items NOT specifically identified by SDG are evaluated using our "Matrix Judging" system - Section 3 of JRM. Section 3 covers CDCIF Appearance of Originality judging - Configuration, Date, Completeness, Installation, and Finish - all weighted equally. (e.g. "Date" issue is a 20% deduction on Originality.) If after judging, 10% of Originality points remain, then Condition can be judged. Originality is judged without regard to Condition and likewise Condition is judged without regard to Originality.

Other Standard Deduction Guidelines address how to apply CDCIF under certain circumstances, e.g. change of interior color. Long way to get around to your specific question:

Standard Deduction Guideline #13 addresses how to judge replacement parts. The worse case, significantly dissimilar - 100% deduction, situation is noted there.

Not having seen your exhaust system can't make a call. Typically, these systems are markedly different and get a total deduction.

That's great, thanks again Dave! I will be ordering the JRM and TIMJG.

Phil where are you located. I have the original exhaust from a late built 96 GS number 900ish that was removed at +/- 10k miles.

I'm in Lincoln NE

Brad is in the last day of prep for his Nebraska "Last Blast" two day judging meet. Probably not checking Tech Board or email. I'll see him this afternoon or tomorrow morning and mention your request.

Re: 96 GS exhaust return to stock

OK I understand. It's nothing urgent for sure. Thanks for letting me know.

Re: 96 GS exhaust return to stock

Phil, thanks for your patience. The exhaust is in my warehouse and I'll get you some pics. I am in the middle of a judging meet and then off to Frisco for the regional so it may be a few weeks until I can get back to you.

Re: 96 GS exhaust return to stock

Hi Brad. Sorry to be bugging you so much! I'm not very good at these forum software's so I was just wondering if I'd connected with you again. Have a great time at your events! This is in no way an urgent deal so get back to me when it's convenient.
