Exhaust resonator type choice

After installing the correct engine brackets for a manual trans my exhaust no longer fits. The down pipe bangs against the body. The way I see it I have two choices. I can cut the first hanger and flange off after the down pipe and reposition them or use this as an excuse to ad a resonator where the cat would normally reside.

If I Chose to add a resonator these seem like common choices:

#1142 Vibrant Performance Ultra Quiet Resonator 3" x 10"
or
#1794 Vibrant Performance Exhaust Resonator 3" x 12"

Has anyone installed an 1142 in the cat position that can tell me how it fits and sounds? It seems like it may be a tight fit and I might just go with the 1794 so I don't run in to further issues.

Are there any other inline resonators I should consider?

Re: Exhaust resonator type choice

It you are looking to quite it down i would go with a Magnaflow

Re: Exhaust resonator type choice

is there a specific type from Magnaflow, or your just loyal to that brand?

Re: Exhaust resonator type choice

On my vr4 i wanted it quite. I have tried Borla and vibrant but the magnaflow silence the beat , I am will be cutting my the apeni N1 of my Evo and replace it with a magnaflow very soon .
pick the size you need

Cool. Expert recomndation! Just to be clear can you recall which borla and vibrant resonators you used?

Re: Exhaust resonator type choice

This will make your car relatively quiet, maintain a burble at idle and sound deep enough to let you know it's installed when leaning into it; boost makes it a little bit louder.

These mufflers (you want a resonator and likley it's designed exactly the same way, just with less volume and sound deadening material/packing), use a straight pipe

with round holes/perforations in the internal section of the pipe.

The casing can rot out all it wants, the pipe will still be standing when it's all said and done. Ask me how I know ...

Just installed the muffler in this link (Colt w/4g63t, 264/272, Evo3 turbo, 2.5", 2x90 degree and an over axle section, catalytic installed).

Magnaflow mufflers - not GVR4 specific, 2.5" offset/offset, universal

Granted 2.5" piping is always quieter, so install a catalytic and 1 long or two short

resonators and call it a day. The more length and volume in the resonator, the more drone

you will help to cancel out.


You still need a better muffler to make the car liveable in my books, but 3" usually means

a high flow option and nothing but.

Try a pair of these on:

5" wide, 14" long universal satin finish Magnaflow

Re: Exhaust resonator type choice

I have this same magnaflow on my VR4, 3" from the o2 housing back with a high flow cat. Car is decently quiet but not super quiet. It can get loud when you get on it. I wish the sound had more character, not enough rumble and mostly just a deep tone. It has that typical 4g63 sound but I wish it had a little something more. No idea what I am looking for exactly or how to get it.

I have been considering redoing my setup and running just a resonator or two in line on the straight section of the exhaust: cat converter -> resonator -> resonator, and then just a straight pipe out the back, no muffler. I don't want it to be loud but I want a different sound and some more rumble.

Every 2 years, but 25 year old vehicles are exempt. I wold continue to run a cat however, personal ethics.

The vibrant one was the Ultra Quiet Resonator. i can't remember which one of the borla it was.

Re: Exhaust resonator type choice

Had a vibrant resonator installed today.

It had very little effect on reducing sound. I shoud have got a bigger one. Or just went with the magnaflow. Now I don't have as much boost creep. I had exhaust leaks fixed as well so that may of had something to do with it.

What size? I've been thinking about the vibrant 18" bottle resonator. I've got a 3" turbo-back system and I don't thing the ultra quiet would fit with the extra diameter.

That being said, if your didn't notice much of a difference in sound, that's something for me to consider.

Re: Exhaust resonator type choice

I know :'(

I'm ordering metal for subframe connectors tonight. Talked to the muffler guy about welding it on for me.

That's what your talking about right?

Re: Exhaust resonator type choice

No, he means because they didn't use the pads of the lift on the pinch welds/subframe/frame rail etc. Just swung the arms under there and let them touch the floor and pinch welds. I'm anal, so it bothers me, but I know a lot of quick shops do this. As long as you don't have side skirts lower than the pinch welds, it's probably not hurting anything. You'll never see me do it on my or a customers car at home though.

I think its the 12". I was thinking the same thing about the diameter but seeing this one installed there's room for a wider one.

Re: Exhaust resonator type choice

I did that to a cop car once at work, dodge charger. I positioned the pads under the frame rail and the arms caught the pinch weld before the pads contacted. I didn't notice until the car was already off the ground and figured it would be ok. It was.

On another note, at my old job I saw somebody lift a dodge sprinter by the pinch welds. It looked fine but I know those things are fairly heavy. After he lowered it the doors barely opened due to body deformation. The customer was so pissed. That's always been a good reminder for me to watch where I'm lifting from.

Evan's (EHMotorsports) advice to me regarding resonators was that I should get the absolute longest one I can fit on my car. Anyone here have an 18" resonator that can share their experiences?

Re: Exhaust resonator type choice

I have tried with a meganaflow 3 inch resonator, around 20-22 inch I think. Quiet down the idling and low rev range mostly, according to my neighbor it was quieter. Didn't do much with the high rpm range though. Gonna put on the vibrant flat black muffler later to see if it helps. Right now it has some cheap 4 inch outlet on, my garage door and wall are resonating when I park inside and idling, but not loud to the ear just a very deep rumble.
