Chambered Muffler
whats the best way to get the old school muscle car sound outta my 3rd gen. it sounds so wimpy right now (stock). i heard the key to that sounds is chambered exhaust. is this true? and if so where can i find them. i've seen them on summit, maybe i'm totally going in the wrong direction. if so, someone please set me straight. i want a fairly cheap, good sounding exhaust (but doesn't everybody). thanks!

I sure wish somebody would define what "the old school muscle car sound" really is.
In my 30+ years of following this hobby, what that meant is either a deep-throated sound at idle and low RPM power due to a low-duration cam and restrictive exhaust that killed real-world performance, or a pair of glass packs that made a lot of noise but were still restrictive and still killed real-world performance. Either way, who cares what it "sounds" like? It's performance that matters.
Loud exhaust for daily commutes, late night returning to the neighborhood after an evening at the drag strip, or long interstate cruises just isn't very practical. What should really drive the decision is flow vs. noise control. For that, from the information I've been able to gather, it's hard to beat Borla and Dynomax. Too bad my budget doesn't support either.

Not really cheap but its an option. Ill get a sound/video clip as soon as mine goes on. Its been sitting in the living room for over 2 weeks now.

Check out bullet mufflers, they're cheap and sound nice.
Deep and bassy at low rpms (car alarms are very easy to set off, even at 1000 rpm moving through a parking lot) and it SCREEEEAAAMMMSSSS at high rpms. It sounds like a nascar, seriously. At 6K RPM it sounds EVIL!
And this was WITHOUT headers. Can't wait to hear it once I get my pacesetters on.

Check out these Chambered "Powersticks" from Classic Chambered..

Unfortunately, no CHEVY clips, but these give you an idea of what they sound like.

I'm going to take some measurements this weekend to see which length "Powerstick" fits best (yeah, of course the shortest will fit best, but according to Eric @ Classic Chambered, the longer the better, since more "tuning" of the sound takes place) There's only a few bucks difference in the sizes anyway, so he's not trying to make some quick cash by recommending the longest/most expensive.
For the SB2530 (2-1/2", 30" total lenth) it's approx $60.00/ea., and for a pair to ship from Mich to Fla $14.
The smaller ones were about $3 or so cheaper.
* Don't bother clicking on their "Vendors" links...they take forever to respond (or don't!) Go directly to Classic Chambered for any inquiries/price quotes.
LOVE that throaty gurgle W/O the resonance!

Quick6, that exhuat has so many uneccessary bends and extra piping, the most practical way to get dual tips from a y-pipe is something like this...
and this will cost you about half the price to get done at a quality custom exhaust shop... mine was 330 including the muffler.

The key to a muscle car sound, is a brawny engine with a big cam. Solid lifters help too
