Can anyone recommend a muffler for a 3.5 single exhaust that flows really well but isn't too loud? I'm trying to cut down on some of the drone without giving up too much performance? Thanx guys;).

I have Aerochambers as well. Not too loud but not exactly quiet either. It's supposedly a "chambered" muffler but you can see straight through it, flow isn't a problem.
 
Hmmm.... ok, I will look at those. Thanx. Went to the Hooker site and listened to them. Perfect! Exactly what im looking for. Should be even quieter then the car they displayed with a V8. Quiet at idle and throaty at WOT. Kool.
 
How soon are you going to be purchasing? If I can get my car running soon I will take video/audio of the exhaust.
 
Okay. Mainly need to order some silicone hoses to hook up my FullThrottle MAF pipe. Then I can get it running for a few minutes.
 
Quiet and 3.5" single do not fit into the same sentence. My spell check just started going NUTS on me.:biggrin:
 
I'll throw my .02 in on this. I think that you should go with the quietest muffler that you can, maybe even use 2 mufflers in series. You can always install a dump pipe if you need that extra couple of tenths at the track.

I've had both quiet and loud cars. Here's my reasoning:

1. There is minimal performance gain from a louder, less restrictive muffler. This is from personal experience, but I wish that someone would try several different mufflers at the track (not on a dyno!)

2. Quiet cars do not attract attention from the reckless driving ticket writers; a.k.a. the Police. Think about it, when you hear a loud exhaust, your head turns and you wonder if maybe they want to race. We all love to race our Buicks. Just admit it!

So, with a quiet exhaust system you get 98-99% of the performance, and you can have more fun because you can get into the boost more often because of the lack of attention.

Side note: My car is super quiet right now, and I love it when I take it to the track and line up next to some big-block muscle car and then have to look at my tach to make sure that my car has not stalled at the line. Then, when I cross through the traps first, I then wonder if I've blown a head gasket because I can't tell if my motor is running because the open exhaust and big cam of the other car makes it impossible to hear mine!

The most fun I have with my GN is always the look of surprise in defeat by other drivers who are not familiar with our cars. My quiet exhaust inevitably causes the other driver to underestimate my car. My car may not be the fastest GN, but my simple combo has been loads of fun for me and loads of disappointment for a certain Viper owner in my area.

The most important thing: Have FUN and enjoy your car the way that you like it. That's really what owning a Turbo Buick is all about.

Someone on this board posted a 3 muffler setup that was virtually silent in the past 12 months and I believe it was a 9 second car.
 
I built a 3.5 inch exhaust using a hooker areochamber muffler. It sounded really good. It had less drone than a singe 3 inch with a pit bull muffler. I am going to a dual 2.5 system to quiten down a bit. The 3.5 isnt really that loud though. I am going to sell the whole system. I made it out of mild steel mandrel bends welded together. It goes over the axle and clears stock rear control arms. I would be willing to sell the muffler or whole syetem if you are interested. Let me know. Jeremy:smile:

:eek: :eek: :eek: I wouldnt say much more about the police. You dont want to offend anyone;)
 
I want QUIET, my wife can come up behind me in the driveway in her
Avalon & I don't hear her comming. I have Pit Bulls on 2 1/2" & they are way too LOUD.

The electric cutout on the dump opens in less than 2 seconds.
 
Otto, I told him to put another inline right where the kitty would be...Come to think of it, he may have to install a kitty to pass smog. That would quieten it down considerably
 
Here goes AGAIN......;) Putting a muffler where the cat goes, does VERY little if anything. THe BEST and quietest system you can do (not buy) is to use 2.5" duals with two mufflers under the rear seat, and a third muffler behind the rear axle (stock location) Use two Dynomax Ultra-Flows (or Magnaflows) http://www.jegs.com/i/Dynomax/289/17283/10002/-1/744882|10265 and then use a cross flow Ultra-flow in the stock location Dynomax 17276 - JEGS Here's a picture of the exhaust system on Bob's car. http://www.turbobuick.com/forums/general-turbo-buick-tech/167389-3-mufflers-quiet-system.html A little history is due here. The system was deveoped by a local fabricator (Sean O'Brien) on D. Hogan's car. He runs mid 10's on this system, in 2.5" And has a similar system on his StageII car in 3" that runs 9.1's @149.8mph. The only draw back to the system, is that you can now here EVERY little engine noise. (ever hear a solid roller cam?:eek: ) He can drive up my driveway and I DON'T even hear him. I was expecting him last week and STILL didn't hear him.(and I was in my garage) It is church mouse quiet, and has NO drone and still performs like a 3" single. It IS very costly to build, though. You can save money and build it out of aluminized mild steel, and it should last MANY years. I am going to build one soon for my car. I have a single 3" that has dual 2.5" tail pipes, and I have too much drone drone. (I know, I'm too old) http://www.turbobuick.com/forums/turbo-lounge/194545-new-exhaust-system.html
