Muffler option

First know that the stock muffler is welded to the intermediate pipe from the factory, so cutting is involved.
The over the axle pipe is clamped to the muffler outlet.
I bought the Walker stock replacement mufflers and adapted them to the end of the intermediate pipe after I cut the stock muffler off. I kept the factory intermediate pipe because it is a type of stainless steel and I am still using it after 20 years .
This is on my 96 B4U Caprice which has the same exhaust as the Impala SS.

Complete SS exhaust systems seems to be out of the market........

The Dynomax 2 1/2" cat-back system is available from Summit racing....but you have to buy the pieces individually.

But you could buy all the pipes.....and then the muffler of your choice....because the Dynomax mufflers are NOT loud, versus other performance mufflers.

OR.....in a couple of months when I swap out the exhaust on my '95 SS.....you can buy my current system. It's the ATR 2 1/2" Stainless Steel exhaust with H-pipe.

Louder and higher performing than stock......

FWIW I just bought the Dynomax (walker) 54016 (PS over axle) pipe through Autozone for $29.99. The DS, 54017, is a few $ more but showing up as NA now.

Anyway cheaper than Summit.

 

Put a pair of original 40 series flowmasters #42443 on my ss about a week ago. Definitely louder than the stock mufflers, but not anywhere near loud enough to wake the neighbors. A low grumble at idle and a mild roar at WOT.

 

I did the same with Flowmaster 9424432s (their original part number sequence) in 2002, and left the stock resonators in place. It is satisfying, without severe drone. There have been no problems with the swap, but it's only been 19 years, so I'll have to reserve any commenting until some longer term experience is gathered.

 

Late to the party here but I used the Summit Racing stainless mufflers on mine.Straight through design such as magnaflow,etc.If you want a little more noise and a power bump remove the resonators in the puny 2" tail pipes or replace the tailpipes all together.

 

FYI, the size of the tailpipes does not need to be large as they are not a restriction. High school chemistry tells you why. Removing the resonators is also a bad idea unless you don't mind drone.

 

Not all systems/mufflers drone.I run resonators depending on the setup.Some of us do want to hear our mufflers.
As for 2 " tail pipes not being a restriction,yes and nn the stock 260HP motor that came in our cars probably not.On a hot/modified engine they will be.

 

Flowbastards will drone you right out of the car. Some don't care about it - I could not f-ing stand them. I like the sound of them, but the drone was ungodly. The best muffler I've found for this car and my tastes are Dynomax VT's. They're 100% drone-free (and I don't have resonators) and have a nice burble around town. Once you get on it, they open up and the car is LOUD. The downside to them is their price.

Just about any muffler can be added to any system. Its all about the skill of your installer.

"Burble" 😂...this is my new favorite word

 

One of my cars came no resonators and Thrush mufflers. Nice grumble at idle and kind of nasty when you get on it. Stock manifolds.

 

Any experience with Pypes Race and/or Street systems?

 

Looking to replace stock exhaust system

 

IDK about Pypes whole systems but their X pipe was a good fit on my Frankenstein system......although I always use a muffler shop to install/weld so they are able to "massage" anything as needed

 

Pypes "X" pipe ,nd a pair of Dynomax Ultra-Flo's

 

Damn dude so clean wtf lol

 

 

Exhaust note (sound) is subjective and what I like may not be what someone else does

With that said, regardless of what muffler you use, keeping resonators will/does reduce/eliminate "drone" which occurs in around 2k+ rpm cruising on Fwy

Like many I have a "Frankenstein" (different brand components) in my exhaust all 2 1/2". Edelbrock shorty headers, Magnaflo 2 1/2" CATS, Pypes X pipe, Spintech Sportsman XL, DynoMax OTA and their SS resonators. Mellow sound but does have a nice note to it.

The OTA/muffler connection blew out after 10 years with the then DynoMax mufflers and the sound was considerably louder with just exhaust ending after mufflers

If you like more of a rumble/louder sound than the dumps right after the muffler will give you that. If you want loud mufflers, SpinTech ProStreet are loud...to me they sound to raspy though
