20round

hey guys, my 68 roadster frame is done....i am going too be finishing up the m20 this week,so the motor and trans will be installed by sat or sun.....my car came with N11 OFF ROAD exhaust according too my tank sticker. i have side exhaust on my 65 396 roadster i love the sound,but it is obnoxiously LOUD! but its how it should be. i would like the 68 too have a nice bark too it but not like the 65..
NOW my Questions are?
did they have a chambered exhaust in 68? if so, has anyone ever installed the allens chambered kit on a BB car?
or who makes a OFF ROAD KIT like the factory N11?
also does anyone have a video of either of these systems on there car that i could listen too? give your thoughts here guys..thanks troy

Not on Corvette. The 68 N11 option was lower restriction mufflers and larger pipes.

I bought the N11 welded system for my 68 L36 at Corvette Central. Fit perfectly and easy installation.

Ditto here too. Bought a few exhaust systems from Corvette Central, always went with the larger N11 exhaust pipes. All of them fit great! I try to buy with a sales offer and or free shipping if possible too as Corvette Central has these from time to time.

Your frame looks great!!!

I also bought the N11 system for my 69 from CC. Easy install and fit perfectly.
As I understand it, the N11 muffler was the same as stock except one baffle removed. Pipes are 2.5".
It is not loud, just a slight bit more rumble than stock. It does let you hear that great quadrajet sound!!!
I really like the system.
