I am shopping for exhaust systems. Does anyone have any preferances? I have a set of headers on it but that is it. I have toyed with the idea of Hooker Headers and side pipes but the $$$ are kind of steep. What about the chambered exhaust behind headers, or just a factory replacement behind headers, and does anybody know what a stage 2 system is.
I need to make a dicision pretty soon, I think my neighbors are getting tired of the noise coming from my garage. By the way its a 454.
Thanks
Lonnie

On "The Toy" I upgraded to 2 1/2" from the stock 2" a few years ago. Went with a system from Corvette Central and have been happy with the sound (not too loud, not too quiet - just right).
On "BIGBRRD" the stock system was toast so it all got pulled off. The new system is Heddman 'shorty' headers into 3" Pypes X-pipe into Flowmaster Delta 50s. That produces some RUMBLE inside the car at 55/60 MPH but is nice and mellow at idle.
Lots of choices - HAVE FUN...!!!
I just had the 2 1/2 chambered installed, and it sounds oh so sweet. I cant believe ive been muffling my baby all these years. You also gain some work room with the mufflers being removed. I had an issue with the 255 60 r15 tires I have, but no more. Just remember to order the 2 1/2 transmission mount bracket.

Vette(s): 1972 conv., sunfire yellow, blk interior, blk vinyl and convertible top. Off frame restoration with American Speed 383 stroker engine producing 500hp plus a 200hp NOS system. MSD ignition. Hooker super competition headers with chambered exhaust.
I also went with the chambered exhaust, hooked to Hooker super competition headers. I love the sound and the appearance from the rear of the car.
Does the Chambered System use the same brackets, Mr Mako said something about a transmission bracket? I had a 68 435HP convertable in high school that had chambered side pipes, with them under the car will it sound about the same? That was such a sweet sound.

I can't tell you anything about the brackets but having had a couple of factory side pipe cars, I can tell you that the sound is the same at the rear of the car. It's sounds different to the driver because the exhaust isn't right at your left ear.

The transmission bracket on the original exhuast is for a 2 inch diameter pipe, while the chamber pipes are 2 and 1/2. I forgot to have mine changed. every thing bolted up fine, my only concern over time would be wear at the point of contact on the bracket. You probably can grind the original bracket to fit the new pipes better if you didnt want to buy a new one. The only other reused items are the muffler hanger mounts. I still use the stock exhuast manifolds. The kit I ordered from ecklers included new exhuast tips.
