1963-360HP Corvette Central N11 exhaust system

[Jerry C.]

Thinking about trying this system. Has anyone used it and how was the install? How well did it Judge? Thanks in advance.

They have two types of N11 systems – aluminumized and carbon steel. The aluminumized will stay looking like new – won’t rust (in your lifetime). The carbon steel system is like the original – it will rust. I have heard the aluminumized system will lose judging points. Can’t speak to the carbon steel system – have no idea if configuration meets judging standards. FIT: For me, one side went in easy - perfect fit. Other side was impossible to connect both ends. I called CC, sent pics - they gave me a shipping label to return the one side - in a week I had a replacement. New piece fit like a glove. The problem with the one that would not fit was the two pieces were not aligned correctly when placed in a jig for welding. I am very happy with the system – sounds fantastic --- better than side pipes (IMO).

Lots of prior threads on CC exhausts and how they judge. See similar threads below and search for "exhaust"

I put CC N-11 aluminized system on my 1971 LT-1 last year. Fit was great. Just the sound I was looking for, not "loud" but more noticeable than stock.

From the 7th Edition of the 63/64 TIMJG...

All 1963 and 1964

A footnote reads

No 1963 or 1964 models were equipped at the St Louis Assembly plant with side exhaust. If so equipped, the judged car must receive a full deduction for the entire exhaust system and other modified areas. Coordinate with the Exterior Team in such circumstances.

If a 63 has the "tool boxes" then the off road exhaust will not fit. Have proof. I bought a set from GMC in late 70's. Had them stashed until around 2008 or so. My chassis etc was re-restored and my restorer called me with the bad news. My car is a March 2/3 '63.

John I have a March car and I purchased a N11 system for my 327/340 car w/recesses under seat this set was from Corvette Central, purchased about seven or eight years ago.

I purchased a N11 set from them recently and they were bent perfectly to clear the early 63 floor pans.
