quietest muffler

that i can possibly fit right behind a O/R y-pipe?
right now it is longtubes, y-pipe, into an 18inch dynomax bullet muffler. i need something that is less obnoxious.
is there such thing as a quiet bullet muffler?
or are there any small rectangle ones?

thanks in advance

Re: quietest muffler

guess i need to rephrase this.
there is no catback on the car, so the muffler needs to be able to go underneath without causing clearance issues. directly behind the ypipe.

Re: quietest muffler

IMO any muffler behind the y pipe will not be quite you will have to run it back more.... why no catback?

Re: quietest muffler

was living in ND and due to there winters mine got all jammed up, so i either had to pay a muffler shop to repair it or rip it off. i chose to do the later.
when i moved down, i could not fit it in the car, so it was left behind
i just need a muffler that will not be so obnoxious.

Re: quietest muffler

You could put a cat in front of it. That's gonna quiet it down a bit more. Sure it'll introduce more restriction but any quiet exhuast is gonna be more restrictive.

Re: quietest muffler

Not a whole lot of room for a quiet muffler after the y-pipe or ORP. Replace the intermediate pipe; any decent muffler shop can make you one.

Re: quietest muffler

I thought that one of the main reasons to own a rear wheel drive, V8 powered muscle car was to be able to hear on the street? Stock muffler would be the quietest but why would you want that?

Not everyone wants to drive a ridiculously loud car every day. I for one like to get on it all the time, and I really don't like drawing unwanted attention from the police four blocks away. With that said, I run a 23" long(the big one) Dynomax bullet in place of the CAT and a single 3" in/out Hooker Aerochamber muffler. It's still too loud for my tastes, but there's not much else I can do that won't choke it to death.

And trust me, I know what loud is. My '85 Firebird had 2.5" true duals with two-chamber Flowmasters and turndowns, and my Z used to have a 3" Flowmaster with no CAT. It was cool for about a day and then I got sick of it. I finally put the Hooker on, which quieeted it down, but it was still pretty loud. I finally put the bullet on, which didn't quiet it down as much as I'd like, but it works. Remember, loud !=fast, especially on newer cars. Hell, you can't even tell my boss' CTS-V is running at WOT, but you can sure feel it!

Re: quietest muffler

it was cool or whatever for the last 2 years, now i am sick of it. just want something a lil milder. really just want to put something in the dynomax bullet place.
so a quiet bullet will work.
eventually i will get another catback for the car, but i have other places my money needs to go to at the moment.

Re: quietest muffler

I went for the Corsa. It too is too loud. Nicely built and engineered but too loud! I added a Moroso spiral-flow after the CAT through its still too loud. IF I had it to do over again it would be stock exhaust and an electric cutout. Ted

Re: quietest muffler

Try a noise reducing cone insert. They tend to help out.

Re: quietest muffler

They do make the Dynomax Ultraflo rounds. Basicly the same design as a bullet, but it has a larger diameter case for better sound control. The link below is for a 3".
