In trying to decide if I want to go all-out sleeper or all-out shocker, I had this thought:

Would it be possible to do an electric cutout-type-thing, but instead of redirecting flow to a hole, redirecting to a different exhaust system? That way I could have a super-silent sleeper exhaust system, and when I wanted the GMMG style sound, I could press a button!

Thoughts? Doable?

Bring yourself a few bags of that good old american currency down to ontario, i'm sure for the right about of cash my mechanic can make that happen

Isn't ontario "up" from here?

So you guys think there'd be enough room? Maybe go with a quad setup, and one side would be the loud and the other the quiet.

Or even better, the inside two the loud ones and the outside two quiet... :evil2

My friend's dad had such a system on his "draggin wagon" (1996 impala wagon). I never got to look at that system, but I do remember seeing another system on the internet, which switched from an open side pipe to a muffled tailpipe system, but I don't remember where or which car.

I doubt there would be enough room; usually people just dump the exhaust after the cutouts. That way you have a quiet exhaust and a loud exhausts and it is simpler than trying to fit 2 complete systems under the car.

Look up the Volkswagen R32, I prefer the exhaust on a mk4, This has a 2 stage exhaust that opens the second bank with a vacumme operated butterfly valve, so the 1st and quiet side of the exhaust is always running but once the RPM gets up there the second bank opens up and makes it WAY louder its a really cool system.

Sounds like a great idea. Civilized when you wanna be, Wild, but still tuned, when ya wanna be, too.

I'm sure it's possible, the best prices will likely be at your local muffler shop after you have the engine in the car.

Possible drawbacks are weight and the possibility of failure at the wrong time (i.e. when being followed by a State Trooper curious about your car).

I've seen postings on LS1tech by vette guys who seem very happy with a "simple" electric cutout. I'd stick with that.

Just my $.02.

A bunch of hot rod guys have something kinda similar to this but it doesn't run full length...ie, they have their unmuffled pipes coming out behind the front wheels and then the full length exhaust also when they need it. What would be sick is if you had side exit exhaust in front of the rear wheels and then a single oval shaped "sane" exhaust out the back. Then you just need some kind of valve/diverter type thing wired up to close off the one your not using.

IMHO it's really not worth the time or money that your going to spend just to get a different sound out of your car...why not spend the money on FI or even engine internals. Guaranteed for that amount of money you could get some serious power out of the LS motors with just internals...

All right, so earlier I thought this was one of the most useless, cost wasting ideas I'd heard of (sorry) but then I was looking in my trusty Summit Racing Catalog and came across a really cool little piece of kit. Check this out, makes it so you can completely open up your exhaust via a cable and lever in the interior. Only 49.99 a piece!

My thoughts would be to run the exhaust through a presilencer or premuffler to get it to your "loud" exahust. Then to a cutout. One side of the cut out being open (or to a tail pipe) the other going to a secondary muffler to make her quiet. Could set it up a lot of ways I'd go with the quiet muffler on one side and the loud pipe on the other. The presilencer being in the middle where the catalyist normally is. Wouldn't add much hardware but could prove interesting.

Another though is if you are just wanting LOUD then put the cut out in ahead of the muffler and only open it enough to make it the loudness you want.

Personally I'm for quiet. It is possible to get good noise reduction and good performance. Just cost a little more $$ :)

That Mr. Gasket cutout you have pictured there will eventually leak and sounds like crap. I had one on my camaro before, and all it did was sound like an exhaust leak when it was closed. I've heard electric ones leaking also. Really not worth it in my opinion. If you are going to go with a cut out, make it a bolt on plate so if you wanna go to the track or somthin its simply 3 bolts to take it off one pipe. Not as easy, but they don't leak.
But yea trust me, last thing you want is that nasty leaking sound.

You should just go with a nice sounding exhaust thats inbetween. Where people know its a beast but makes it seem like ur tryin to hide it.

Or get some butterfly valves in the exhaust...popular as OEM nowadays (C6, Evo)

The R32 system is the same system that is used on the lamborgini gallardo. It is called a flapper valve. Many of the vw guys have tried some of these electonic closing valves but you have to think that with such heat passing by a cut-off that sooner or later it is going to seize and most companies don't warrenty for this. I know there is atleast one system out there for the 1.8t MK4. Just a thought

Yeah, a cutout with a lever in the cabin is the REAL old-school stuff. The new age spin is that they are now available with a remote acutator so that you can flick a switch in the cabin and the cutout opens, flick it again and it shuts.

The was an option on Porsche 996. Friend's got a C4S with this installed.

yea just get a cutout. my buddy had oneo his integra a long time ago and that thing was scary loud.

Really? A factory option? That is pretty darn cool. Those crazy Porsche guys...you never know what they're going to do next

Standard on Mitsubishi 3000GT VR4. Those cars had more toys than almost anything else.

The automatic flapper valve is also used on E36 328 models, has a vacuum-operated valve in the muffler.
