I have decided to make the leap and have a custom exhaust fabbed up for the R. Gonna be 3" from the DP back, and using a Magnaflow Muffler.....I have 2 questions.<p>1. Sould I put in a resonator?? I DO NOT want it to be ORIGINAL Evolve or Svenske loud....I want it to have a nice cruising tone, and sound like a monster at WOT....and a small amount of interior resonance is ok.<p>2. From what I see, the Magnaflow P/N: 14219 is what most are using in their Svenkse system to take it down a notch....is this the correct P/N?? I just want to get these things right before I place the order.

Re: To Resonate or Not??? (s60rdood)

You probably will need one. That being said, as long as you have 18" of straight pipe left somewhere (and you will), you can always add it later

Re: To Resonate or Not??? (JRL)

I had a 3" from the D/P on back custom bent with the Magnaflow muffler in question. Yes it ias the right part #. I have a 10 month old son so being quiet when needed was a must. At idle it is not much louder than stock (with a burbling sound) and easy on the gas, it is quiet enough to not wake my sleeping son (with windows up or down). I have no res on. When I get on the gas, people can definately hear me coming. Is it loud under full pull? Yes! But only when you want the car to be loud. When I drive with my son (or my wife) the sound is perfect. Enough to know something was done. If the stock system was a 3 on a scale of 1-10 10 being the loudest. Then with conservative driving it is a 4. If you get on it, well then it is a 9. I hope this helps, Rick

Just ask Phuz! He just did something close...as did I.<p>If you ask me...put the rez in and don't think twice about it. Mine (C70) is just simply too loud with only one Magnaflow and cat...it takes all of the pleasure from the audio system...<p>Cheers,<br>Prospero

USE A RESONATOR!!!<p>that is...unless you want your car to sound ricey <IMG NAME="icon" SRC="http://www.vwvortex.com/zeroforum_graphics/screwy.gif" BORDER="0"><p>my system consists of this: 3" from the CAT back, and going through a very short 3.5" in/out glasspack muffler. For details, look for the thread called "Two volvos go exhausting! S60R and C70"<p>Despite the fact that most of my friends think its OK, I am NOT ok with it. It is too loud for daily driving. I go back on Monday to have a resonator installed.<p>

Nice, you all gave me VERY good responses, thank you!! I'll order the Resonator and Muffler tonight. My buddy works at Meinke, he's gonne be the one doing the work. I'll have him make an extra straight-pipe, and put flanges on everything so I can swap the sections out. Thanks again, these were the responses I was lookin for!! <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

I know we are talking about something a lot different than stock here, but, the other thread has so many people praising removal of the resonator and then in this thread it says it makes the car sound "ricey" Seems like if it makes a modified exhaust sound more ricey then removing the resonator would make the stock system sound more ricey.<p>Since we are talking about resonators. I can't remember if anyone provided conclusive evidence that removing the resonator from the stock system provided a performance improvement or does it just give the exhaust a throatier note and have a placebo effect on the driver?<p>Isn't the resonator just a bulged piece of pipe or does it some kind of baffling/restriction in it like a muffler?<p>Ya, I'm clueless.

Re: (jazee)

I could explain the difference between the resonator on stock or custom setup...but I'd go into too much detail, and it would just be confusing, so I'll let someone else chime in that can sum it up better.<p>Not sure of actual dyno numbers for JRL Mod....some have reported smoother shifts, snappier response on the highway, just little improvements....someone that has access to a dyno should give it a shot and see what it does if anything.<p>As for the resonator, it IS a bulged piece of metal, but has a "honeycomb" core in it with fiberglass mat or another sound absorbing material in it.

While I really don't know what a resonator looks like inside, I do know what they do. Remove RESONANCE. A muffler MUFFLES sound, as in, drops the volume by smothering it. Two reasons it doesn't sound ricey.<p>1) The 5 pot has a cool warble to it (just watch a classic rally rerun on speed on watch the old Audis to see what I mean) that sounds good. The warble helps to mask most of the unpleasantness.<p>2) The resonance that is heard when the exhaust is removed is not high pitched, metallic or tinny like a fart mobile. It is more like a burble or a growl, and turns into a kind of shriek when at WOT. I read people describe it like an old british sports car, and that hits it on the head. It's much deeper and pleasant than that twangy zing you hear from four pots. It's like the difference between James Earl Jones making car noises and Gilbert Godfried making them. <p>The stock muffler is VERY quiet. You can't hear squat with the stock muffler and resonator in place. It's still pretty quiet with the resonator off and muffler on, but a bit less restrained. Very classy.

Re: (needsdecaf)

The resonator is basically straight through under pressure. The interior wall is not perforated or anything.<p>There is a port at the front of the resonator that opens the inner path to the outer shell of the resonator.<p>This appears to be only a pressure chamber that mostly affects "feedback" under deceleration. I noticed more noise then than when accelerating in the brief period between removing the resonator and installing a DP and cat-back.<p>It was only mildly louder on throttle.
