Hi,

I have Stillen B, Y, RT cat and Stillen muffler, the sound is getting a bit loud for my quiet neighborhood. I called some muffler shop, some has resonator, some has glasspack. My question is are they the same? Which one muffles the sound more? I've been quoted a 24" resonator installed for $90 to 28" glasspack installed for $60. I know, it's an oxymoron to buy a Stillen B-pipe, but to cut it and put a resonator back in there. Before you suggest putting the stock stuff back on, the answer is no, I dont' have my stock B-pipe and stock muffler anymore, so I have to work with what I have now. Plus I love the look of the Stillen muffler!

Any suggestions would be greatly appreciated.

thanks,
Tifosi

 

Glass pack is an archaic term for a straight-through resonator. They were louvered-core, which is bad. They also used fiberglass packing, hence the name.

Any resonator you get, no matter what the moron at the shop calls it, should be a perforated core and use stainless steel packing. Accept nothing less. And if you are trying to stay quiet, get the longest one that will fit under there.

 

Thanks moderator!
I called and they have the "true" resonator in 12", 24", and 36". I'm just debating whether to go with 24" or 36".

Ahhhhhhhhh, this brings music to my ears! Sorry you have now found out what others are in denial about for so long. You could have bought the stock SE 00-02 muffler and have the sweetest sound you want(of course with a drop in panel K&N filter). What some people will do for sound!

 

"WHAT?? WHAT DID YOU SAY? I CAN'T HEAR YOU!"

So, anymore suggestions? If not, I'm going with the 24" resonator.

I used to drink Advils to prepare for my NY/Maryland trip, this was due to the $200 Naxos muffler that I had on my 3rd gen. I ripped it out after I accepted my screw -up and acknowledge to my wife , that I do not know **** about cars!
Good luck.

 

Back when I was jacking with my exhaust (4 revs in 2 years...now I'm stock again), I replaced my stock 2.25" resonator with a 24" long, 2.5" diam Magnaflow unit. The unit sounded nearly stock but did add a hair more noise to the exhaust sound. It was a good unit although only a thick-walled aluminized steel rather than stainless.

I think if you do what you propose you'll be happy with the sounds. Make sure they paint over all welds (adds some corrosion resistance) and use 2.5" piping. Chances are slim they'll have a mandrel bender but even the crush bends are pretty decent nowadays.

 

Does a resonator restrict the air flow any? I mean, do you have to give up a tiny bit of flow for sound quality is what I want to know.

 

Essentially none.

A resonator is literally a straight piece of pipe that has lots of holes in it. In between the pipe (where the gas flow is) and the outer case is a bunch of sound deadening material. The only restriction to flow is due to the increased surface roughness over a straight pipe. It's pretty much negligible for all intents and purposes. The restriction is orders of magnitude less than the restriction caused by a chambered muffler, which is basically a maze that the exhaust flow has to find its way out of.
