Just stock mufflers with be fine.

 

Tony got stock replacement mufflers for his sisters GTP and the car is quite is fuck.. and it;s a DOHC motor

Something i have heard from other folks with a 3.1/3100:

 

I have heard of people using the DOHC Mufflers on their 3.1's and it is almost silent exhaust.. (I dont know for sure as I have never done this..)

 

I will say the exhaust on my 94 w/ 3100 is pretty quiet (When the gasket at the flange off the manifolds isn;t cracked).. I can sit in the car with it running in park, and no music, and I cant tell its on.. Now, the growl the 3.1 has I dont think can be quieted down..

I know what you want, but I dunno if you'd ever get it that quiet...the motor itself is fairly loud (well, mine is anyway)...the 3L vulcan in my sister's Taurus on the other hand is not loud at all..the dying accessories make more noise...I love the exhaust on her car..so quiet lol..

 

i'm pretty sure stock replacmeent mufflers are not going to be enough for what "I" think you're trying to achieve..dunno if anything would be able to quiet the 3.1 down enough to heard the fuel pump running lol..

yeah i know it wont be completely silent, but i want it quiter than stock.. the thing is that people are 100% wrong on what the 3.1 is compared to a 3100, 3400, 3.4, or 3800.. the 3.1 shouldn't even be in the same group as tyhese engines. the 3.1 witch a stock exhaust sounds like an aftermarket xhaust no matter what. the thing i hate the most is how at 2000 rpms in drive, it makes that loud obnoxious rattling sound.. GRRRRRRRRRRRRRRR i hate that!! i'm gonna try some 3.8 mufflers i think...

what about some Buick mufflers? The newer regals are whisper quiet.

My old Lumi had the original muffler on it.. Growled reeeeal nice until about 4500, then it all but disappeared :willynilly:

When I got the lumina, there must have been a hole in the pipe before the muffler already because it was kinda loud. Then it broke and was extremely loud. I did a quick fix and it was as quiet as I ever heard it. I actually tried to start the car after I had already turned it on. When I got around to fixing it for real, I got a muffler from summit for $40 and it has a real nice growl to it.

 

Moral of the story: Stock is pretty quiet.

well, my car runs rich as hell so its gonna be loud... im gonna probably finally bring it into my friends shop and diagnose it and see what i get..

:thinking: i dunno bout that...my stock exhaust on my 3.1 was really quiet before it got a hole in it.

With a new stock muffler my 3.1 is extremely quiet out the exhaust pipe. The motor is not quite so quiet on the other hand.

mine has a tiny hole in it, it's for letting the water out so it won't rot out .... perfect circle .... :willynilly:

my 3.4 with stock exhaust to my knowledge is completely quite and I can't tell that it is running at idle.

basically the same here. I believe theyre stockers, only thing replaced (to my knowledge) was the cat that used to rattle from 2000-3000 :lol: it annoyed me for 3 years til I finally got it replaced

My Lumina (3.1) has stock exhaust, and I've had people ask me what model Flowmaster I was running... :lol:

yeah all the older 1st gen's were louder than the newer 1st gens. I believe that was because they added a resonator to the 93/94's?

I love the growl.

 

My exhuast is pretty quiet too.....specially for 12 yr old stock exhuast.

I think that they did, but I'm not sure. In fact, according to my RPO sheet, my car was originally spec'd for the "Exhaust system - sporty" package, so who knows... :lol:

 

Hell, I drove around a 92 Regal the other day that also had a 3.1 in it, and it was as quiet as a mouse! I said to my self, 'damn it, that ain't fair!' :lol:
