looking into a chambered exhaust. What a the pros and cons?

Hey gents, sorry to jump into this topic but I have a question. I currently have a 383 stroker on my 69 Z28 and looking for exhaust options. I currently have a set of 2 1/2 dual magna flow exhaust coming out of 3" headers on a budget but looking into a chambered exhaust. What a the pros and cons?

The chambered exhaust is actually more restrictive than the regular exhaust. The mufflers sound like glass packs. I would try to talk you out of it.

Re: looking into a chambered exhaust. What a the pros and cons?

My 68 has a chambered exhaust. Mufflers? What mufflers? There are none. Maybe I'm confused on the engineering, but I thought the chambered exhaust was less restrictive. In my opinion the sound is more like a side pipe Vette. Which, I think was the same design only obviously shorter.

Noise noise noise. You better take a ride in a car that has them first. You may also need Asperins.

I would agree with you. I used the chambered exhaust on my Model A Tudor (355 sbc LT1 with headers) and it sounds great. IMO

The saying "If it's Too Loud You're Too Old" comes to mind.

Having heard chambered Z28's, Rice Krispies comes to mind.

A whole lot of Snap, Crackle and Pop.

Re: Mid Year Vette Side Pipes

That second video is a hoot! It looks like the salesman wanted nothing to do with shooting it. Just get the darn thing over with in a hurry. I was getting dizzy just watching it.

Re: looking into a chambered exhaust. What a the pros and cons?

Chambered exhaust is very restrictive, as much as 20% loss over other quality exhaust if I remember what I was reading. It's been discussed a lot here and on other forums so there is a lot to back that up you just have to search for it.

As for the sound, the chambered exhaust needs the right compression and cam. Think DZ302 or solid lifter BBC like a 427 copo engine as examples that work if you want that snap, crackle & pop tone.

In the end you'll lose power and you may not get the note you really want out of the tail pipe depending on your combination!

Re: looking into a chambered exhaust. What a the pros and cons?

I have chambered exhaust paired with my 427 COPO engine. I personally don't like the sound, and it seems more restrictive to me as well. I will be changing out my chambered exhaust either this winter or next spring. Going to spend some time figuring out what I will be converting it to. I like loud exhaust, the chambered exhaust is a different kind of loud. Hard to explain. Snap, crackle, pop.

Re: looking into a chambered exhaust. What a the pros and cons?

I used chambered exhaust in my old 72 vette. ZZ4 crate engine, M20 4spd, Flowtech headers into 2 1/2 (undercar) chambered exhaust. I have read that it is more restrictive than other exhaust systems, but not sure how much hp you would actually lose. My car dyno'd 262 rwhp. Other vettes with the same running gear but with mufflers dyno'd about the same, 260rwhp-275rwhp. The vettes independent rear sucks up more power than just spinning a 10 bolt straight axle. I don't know what a 67-69 Camaro with that running gear would dyno at. Could search it. Anyhow, back to the sound. You either love it or hate it. Its Snap, Crackle, Pop meets a Rip Saw! I got many compliments on the exhaust sound. Open it up under a bridge or tunnel and you swore you at Daytona. The higher you rev it, the better the sound. The vettes fiberglass tub of a body does strange things to vibrations/sounds. Amplifies them. Personally, I like the distinct, rowdy sound. Mellow and soothing, ITS NOT. Ride in a buddys car first. It sounds different sitting in it than it does standing beside/behind it.

Re: looking into a chambered exhaust. What a the pros and cons?

I removed my chambered system after a long 4 hour drive with all the in-car noise...couldn't here yourself think after a while. I went with Walker Turbo's and it actually lowered the in-car noise, but retained the nice rumble outside. I can actually enjoy the music now with a more pleasurable drive.
