Default Resonator question...just a quicky

Does the resonator quite down the exhaust by only lowering the volume, or does it actually change the tone aswell?

it really doesnt change the tone, and it also really doesnt lower the volume "THAT" much. it does however slightly muffle/ take away the crackles and crisp sounds that the car makes during engine breaking, and acceleration. Its pretty hard to describe sounds! and im not sure if you know what i mean by crackles, and crispness!!!!! ha ha ha... im not talking about the popping that the subarus make though. oh well,, i hope this made sense!!!! uhhhhhh it muffles it slightly!

Ok then, what about installing an glasspack/cherry bomb? I don't want to replace anything for the glasspack, just place one in there to quite it down and hopefully get a bit of a lower tone going.

I'm trying to get my exhaust to sound meaner, I have Borla Headers, and a Stromung unresonated Catback. Does a high flow cat or running catless make it sound meaner?

I always thought of a resonator as making more sound because of the root word "resonate."

Not to highjack, but I want my car to sound like a WRC car. How can I do that? I'm thinkin Scoobysport muffler, and then when I swap in my v6 motor, scoobysport downpipe, and no cats anywhere!

I think the resonator is ment to reduce resonating.

Wanna sound like a rally car? Two words strait pipe.

straight pipe=LOUD and crackly
with resonator=loud no/or very few crackles
multiple resonators=much quieter and no crakles at all

I'm about to add a glasspack to mine to eliminate the crackles on it. If you do this though, make sure they put it in backwards. By doing this it won't change the tone or slow down the gasses. It will just reduc or eliminate the crackling and quiet it down a bit.

Just get a dynomax race muffler and put it inline...its pretty much a resonator without any flaps, so its reversable, and wont block the flow. Theyre also only about 35$ from www.Summitracing.com

I don't want to change my muffler. I have a Stromung SS Dual tip muffler that is the bizzomb. The exhaust is just a little loud and a little ricey for my tastes ever since I went with the MRT header back system. (with the extra power, this is the only regret)

It sounded wayy better when I was running the stock exhaust with only a Stromung axle back.

No, what I mean is put the dynomax race muffle in your midpipe, and make it like a resonator. It will do exactly what you want and is really small and cheap. I wouldnt give up a stromung either!

I too have a dynomax inline between the muffler and where the cats normally go. Seemed to help out a bit. And no cats does make it louder.

Trust / Greddy mufflers usually emit a very deep tone. I had an old Trust 'sport' muffler on my Impreza, it's a straight-through, but with a big chamber like a conventional muffler. Sorry if that's not the best description. It sounded great though, but was a little loud w/ no resonator.

But will I have to replace my Stromy for it, or could I place it in the mid-pipe somewhere?

No, you keep your Stromung muffler. You just integrate a resonator into the midpipe. Resonators are usually 14''-30" but more commonly between 18''-24." Take it to a muffler shop and they will cut out a piece of the midpipe and weld the resonator back in it's place. This should quiet the loudness and get rid of the crackles and pops. Some people use glasspacks for resonators, but whatever you get, you want it to be straight through.

Obyone, the reason the exhaust note changed is b/c you're now running an equal length header with a balance tube. A resonator will not give back that "boxer sound" Harley-like rumble, sorry.

NicGordon, to sound like a WRC car you need:

1. a turbo
2. launch control

I was thinking about adding a straight-thru perforated core glasspack to my custom exhaust. My question is, if you buy a straight-thru resonator/glasspack, what difference will it make if you mount it frontwards or backwards? It's still straight-thru regardless of how you mount. I don't know, maybe I'm about to learn something here.

I have a NEW Stock RS exhaut system sitting in my garage....


I have an idea and tell me if its smart

Slicing it open on top (muffler), welding a cherry bomb inside of it straight through... and rewelding it closed , then mounting it..

You think this would work ?
(stock look, better sound)

Its just sitting here, and I would hate not to use it.

If you look inside of a glasspack, there are little cup shaped fins. When mounted forward, these catch the air and will slightly reduce flow velocity. when mounted backwards they just disturb the airfolw enough to take out the crakles and pops.

I would keep it and when or if you ever get rid of your car, put it back on and sell your aftermarket exhaust.

I would let it sit in the garage since its only 1 7/8" piping.. My exhaust is 2.25" from my Borla Header through my trackpipe to my Stromung Catback.
