How to quiet down a mark?

[slowmark95]

I have been getting increasingly annoyed with how loud the old mark is. It has the stock base exhaust system on it with hallowed cats, resonator delete, and Thrush weld mufflers (flowmaster 40 clones) in place of the factory mufflers.

I was thinking of adding a thrush turbo muffler where the resonator used to be at, but they are not offered with a center inlet and outlet. I know this would quite it down, but I'm not sure if it will fit.

The other option was to add a straight through glass-pack type muffler, which I know will fit, but not sure will quite it down.

I would like to keep the thrush weld mufflers installed as they are because I no longer have access to a welder. I plan on just using clamps for what ever I add to the center.

What are your recommendations?

All the mods you've done to the exhaust have helped make it louder...

So ... undo it

Yeah I will simply hit the undo button.....should fix it rite?

But on a serious note, would a glass-pack type muffler even quiet it down?

Two options.

1: Change mufflers to lets say, stock.
2: Sound isolate the whole car (especially the trunk area and such).

Choose your weapon

This is why I wont change mufflers on mine. Even though I want the 4.6 to really growl as it can do without any problems, it's not suited for a luxurious ride

Glass packs?? How does the word "quiet" even enter your nugget when talking about glass.. yeah they're quieter than Satan screaming directly in your ear hole I recon

I would have done that, but I tossed the stock mufflers.

Option #1 would make it quiet again.

It looks like that's out of the question then. Is there a compact muffler that would fit where the resonator once resided? All I could find was a glass-pack.

I'll have all the stock stuff within the next week or two. Mufflers, resonator and all. Mine is coming off and being replaced with other stuff.

Option #1 would make it quiet again.

#2 would also work. But you probably need to put a lot of effort into it and in the end it would probably still not be as quiet inside as the original mufflers.

Let me know how quite it is and what you used. I need exhaust work soon and don't want loud, not for this car! Quite is the key!

if you want to go cheap, get some newer stock mustang GT mufflers..people usually throw them away after installing aftermarket exhaust..they have a nice rumble and flow pretty well..and deffinetly quieter than a chambered muffler.

If you want it more tame, put a resonator back in place and your problem will be solved.

I have something like what is pictured above on my blown97 with stock logs, gutted cats, and magnaflow mufflers and my car is super quiet but will growl at WOT.

A lot quieter compared to this. Lol

Lots of good ideas here! Im having a difficult time finding mufflers with the center inlet/outlet or off-set inlet/outlet configurations.
NoLimit was kind enough to offer me the stock parts from his car, so I may just go that route.

Back in 1999 I had a friend with an annoyingly loud fart box Honda. It had some type of Greddy exhaust system. After about 6 months of dealing with the noise he went to the muffler shop & asked how he could quiet it down. They added 2 glasspack mufflers to a section of straight pipe. The car went from an annoying fart box down to almost stock. Just a very low rumble.

If you swap your regular exhaust for glasspacks it's obviously louder but if you already have an aftermarket exhaust, the glass pack muffler does muffle the sound when you replace standard straight pipe for it.

These are the mufflers I run on my 98. You won't find a much better price anywhere for what you see here:

Cheap fix, get summit turbo 2.5 inch mufflers. Trust me...

He's going to get my resonator and stock mufflers when I remove them. I'm going to try and sell my third cat on eBay myself for a decent price. I wonder if it would be a good candidate for platinum scrap. Some people make good money on these on eBay. Just have to weigh them out and I guess the buyers do the research. Can't hurt to list it and give it a shot. I might recover some of the money I have put out on everything.

Not much of a description but look at what he's getting out of it.

I wouldn't go through the trouble of chopping off glasspacks to have stock heavy ass mufflers welded back on..just get cheap turbo mufflers that actually flow well still and put em in place of the glass packs.

I agree but if he wants to pay shipping for these, I got the boxes already for them. I think they weigh in at about 20 to 30 pounds each. I don't know about the resonator. He has plenty of time to think on it. My stuff hasn't even shipped out yet.
