Quieting down a loud PV muffler?

[Tone]

Mine is mounted in the middle of the space where the stock muffer went with almost identical lengths of pipe before and after the muffler. John has recommended it be closer to the front with the added pipe going aft of the muffler, i.e. cut off stock muffler, weld new muffler to where pipe was cut going into the stock muff, then add pipe from end of PV to beginning of pipe over axle.

Those who want bolt on could have the muffler shops add pipe and flanges to the PV so it could bolt on in place of the stock muffler.

Realize that the PV2 is significantly smaller and shorter than the PV1 or the stock muffler and as such is much easier to mount.

My PV2 is almost as close to the front as possible. Looks like only maybe 1" added to the front and a longer piece at the back.

Definitely sounds like having it mounted closer to the front tones down the resonance a bit. I am noticing with mine that the temp and/or humidity outside seems to make quite a bit of difference to the sound. When it is cooler and wetter it seems to be louder.

I just had mine installed yesterday. And my first impression was that I had a faulty exhuast. It sounded good at idle, but when I gave it some throttle, it was LOUD. Almost embarrassing. I even crawled under to look for leaks. At 1500-2000 RPM it resonates in the interior. Above 2000RPM at cruise, it is SILENT. Go figure. I really think it will mellow, because it does not sound like the PV that I had heard before, whether PV-1 or PV-2.
It is mounted with equal length extensions on both ends and welded.

I am looking at a resonator too. Am I correct when I measured a 2 inch diameter tailpipe?

Hey dude, you heard mine. Is it like that? because mine mellowed out a lot from my exhaust beginning to break off at manifold when you heard it in Moab.

Like I told you in those Pm's.....you will not be sneaking up on any one ever again!!!

It's louder. I have to admit, it seems like it's getting mellower, especially after it gets good and warm. Doesn't sound as brash. But the resonation at 1500-2000rpm is gonna take some getting used to or an exhaust resonator tip installed to take the edge off.

Nocturnal got really lucky...his sounds perfect!

I hate to say it but it's starting to sound like a quality control issue in production. A more noticeable note from outside of the vehicle is acceptable, but interior resonance can be extremely annoying on long trips.

Just installed mine yesterday and I really don't find it as loud as I thought it was going to be. It sounds a little more ricey than I thought, but it is definateley a lower pitch than a ricey one. Overall I think it sounds good, I think it will sound better later. The noise on mine is no louder than my tire noise (under normal driving, if you step on it it will get loud but not too loud). And if it hits that "beer bottle effect" then just let off the gas for a sec and reapply, it seems to go away 90% of the time. Of course I have only drove one day and I don't think the beer bottle effect happened inside my cab, but I could hear the tone of the muffler that you are describing (I just let off a bit and it went away) I had my muffler mounted up front due to Tones post

I love the sound of it when you start it up, it just puts a smile on your face. Track times with this mod coming Monday.

I really don't know what the deal is. It most definately gets a little quieter when it warms up. I am still looking for a tip.

Starting to sound like the Borla exhaust I had on my Jeep GC few years ago. Man did I get ricers come up and try to race. Funny the first few times but after that it got really annoying. Kinda like how you go camping and the mosquitos won't leave you alone? It's the same feeling.

I suppose from a performance stand point the pv is probably worth it. And the Borla for the Jeep did mellow out alot after a year or so. It also sounded quieter once it got hot. Come to think of it, the Neuspeed exhaust I had for my VW GTI was exactly the same way. Loud at first but mellowed out after a year.

I think I'll order one in two weeks or so... when I get hired. *cross fingers*

I can tell you, and I hope other PV1 owners feel the same, that the PV1 DEFINITELY quieted down after a few months. I've had mine installed for over a year and it is a LOT quieter than when I had it installed. In fact, at some points I wish it were a little louder... although it doesn't really matter. I love the hum it makes while cruising, and the growl it makes when reving.

Supposedly, the PV2 is a bit more open, so it may be a bit louder than the PV1 brand new, but I have no idea. I'm assuming they probably sound very similar and over time will, too.

It's was a little quieter than I expected, but a bit more than the neighbors were expecting (out of lil ol' humble moi).

To get the idea of how it sounds simply put you lips together and say PPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPower Vault!

I really hope it mellows out as much as everyone says it will. I have mixed emotions right now about it. I love the way it sounds while cruising. But the growl everyone talks about under acceleration sounds like a coffee can. I am going to Car-X tomorrow to discuss some resonator options. At this point if the tips are as expensive as everyone says they are, I could have bought a cat-back.

The shop that installed it ($40 cash) said that, as with all glass-packs, it should certainly mellow-out after a few weeks of use. Heck! I found that driving it through 6" of rushing water down rain-swollen Atlanta streets mellowed it out only minutes after I left the shop.

I am pretty pleased with how much this muffler has mellowed. I was searching the the old threads on Vmag and found this posted by FeatherFoot. I believe it is John from PV mufflers. I will share this with everyone here if anybody is looking to quiet it down futher.

"...loudness can be reduced by replacing the 3" tip on the stock exhaust with a 2-1/4 tailpipe. That tip actually acts like a megaphone which increases the sound level. Another option is a resonated tip which will reduce the sound even further. Do not go bigger than 3-1/2" for the resonated tip or you begin to megaphone again.

John"

The compliments are starting to roll in so I am going to leave it as is with the stock VX tip. Hope others find this info useful.

Mine has mellowed quite a bit. I have the first generation PV muffler. By listening to Tone's I think the second generation PV muffler is louder, but it supposedly is more efficiant and provides increased horse power. I would like to eventually Dynomat the whole vehicle, but summer temperatures have that delayed until late fall early winter. Until then I can put up with the low RPM grumble.
