this also explains why when i shot water in my exhaust it got much louder, i didnt think they had fiberglass packing in a stock muffler.

Great photo..I curious about what look like of Ls1 muffler..I think about make short muffler of ls1 cats. thanks

The only fiberglass was between the two layer of shell. It has an inner and outer shell and just a little fiberglass between.

Don't think it would be any different. According to my research the WS6 has the same exhaust. I am curious to see how much power I can muster out of mine with the stock manifolds and an NA set up.

Very cool. Thanks for posting this.

The tail pipe outlet size is bigger on the WS6/SS muffler, 2.5" vs. 2.25".

I also believe that the chambers may be a slightly differnet design, but I cannot confirm this as fact.

Overall, the difference in flow between the two will be marginal.

i was pretty set on the stock ws6 exhaust after most of whats posted here and the ancient article on the b&b triflow making 1hp more than a ws6exhaust. now after doing two days of searching through the archives this is the most confusing ****. Especially when someone like Damian is saying theres no difference between the std exhaust and ss/ws6. I love the sound of my stock exhaust with the cam, so my concern is power only.

sorry if this is not exciting for some of you, i just like the look and sound of my current setup, plus don't want to spend the money and chop my car up for no reason, this has been twistin my ***** up for two days now. lol

What my no.1 question is making 380rwhp(homeported heads and cam) with a ws6 exhaust how much of a increase would you guess I would get from going to a magnaflow catback?

I have been on this site since its first month of existence and this is the first I have seen this. This should be put in a sticky somewhere!

Look in my sig man. I have owned alot of F-bodies. I too agree that the stock WS6/SS exhaust sounds great but there is a reason the SLP offered the Dual Dual on the SS and the Firehawk. If you can try to find a SLP dual dual exhaust if you can. This is the closest sound you can get to a stock WS6/SS exhaust. I would put any amount of money you will see a nice gain. Remember the piping on your SS/WS6 exhaust is the same as the exhaust pictured. The only thing different is the muffler.

If you like the stock setup, why not just get a cutout for power gain when you want it? Or, if you like the look of the stock tailpipes but want a full-time power gain, just get a Magnaflow replacement muffler to weld in.

Overall, you would gain more than 1rwhp with a muffler/catback upgrade on your setup. I have no idea what the situation was with the dyno test you are referring to, but any decent catback will make more than 1hp over the stock WS6/SS system.

yeah i guess I'm going to have to do it. its perfect timing as my car is 2.5' in the air as my trans is at TDP for a freshening but I wanna run it with this exhaust first so I have a before after comparison. Last time I ran the stock clutch was bellowing smoke so I only got one run in. I would be happy to pick a mph or two.

I would like to see some cutaway photos of a WS6 or SS muffler just for comparison to see if there are any differences. Anybody?

That is interesting. Thanks!

Cut out would work but then he is still stuck with the 2.5" piping.

Discomonkey,

Sent you a PM I have the exhaust you need

RPM WS6

iTrader: (3)

Only the tail pipes. I pipe is 2.75".

MikeWS6

I could be wrong but I thought the base models were 2.5 and the I pipe for the ws6/ss cars were 2.75. Either way a 3" catback would help a bit especially if he were to mod his car later down the road.

RPM WS6

iTrader: (3)

All V8 models received 2.75" I-pipes. I have a WS6 catback and a Z28 catback in my basement, the only piping difference is the tailpipe diameter (2.5" vs 2.25").

MikeWS6

Cant wait to dyno my car again and see if I picked up any power going from 2.75 to a full 3".

wow pretty cool! I always wonder what it looked like inside one! Thanks!

I have a WS6 muffler that I'd be willing to cut open in the name of science, but I have a feeling that it would be identical to a stock muffler in its chamber design, and just has larger piping.
