that sounds mean to me...a little high pitched at high rpm but sounds great at idle...

vehigaz, do you have any type of soundclip for that exhaust??

[rowhard]

a little high pitched at high rpm

can you say RICEY

and that isn't even an American spec which means more power. My Morgan tech sounds as good

[pbkid]

agreed..i love the morgan tech stuff but i dont think he is making products anymore..

and i dont think 'infiniti' would agree with you much on the 'riceyness'

As it happens, I just tried to record my exhaust note for PittVX, but was unsatisfied with the results I got from the equipment I had to work with. An exhaust note has lots of highs and lots of lows, and a cell phone or camera just can't capture both ends of the sound - you need pro audio equipment to record it, and a very good sound system to replay it. By that same token, don't expect that your new muffler is going to sound just like a recording you hear on youtube.

The Dynomax has a very nice idle - not as deep and bellowy as a FlowMaster, but definitely aggressive without being ricey or raspy - for lack of a better description, it barks when you prod the gas pedal. I don't know what it sounds like from the outside at speed, though. Inside the cabin, you hear it a bit, but it seems somewhat distant even at full howl. By contrast, the FlowMaster was so loud inside that it sounded like it had been piped up into the cargo area.

My advice to you is to suck up the expense and hassle and try out different mufflers until you find one that you are happy with - but start with the Dynomax Super Turbo series. The fact is that there is just no other way to predict what any particular muffler is going to sound like on your particular exhaust set up while you are standing next to it or driving it.

Good luck!

on a similar note, does anyone have experience with intercooled exhaust tips?

im looking for a way to quiet the pv2 just a hair.. was thinking about an exhaust insert, but saw these tips from borla.. says they cool the exhaust air, mellowing sound, and i could lose the megaphone style stock exhaust tip.. anyone tried somethin like this? maybe that would help you too pb?

ya, i really like the PV2 at low RPM and when slowly accelerating, but driving 80 or 85 it gets really annoying... i was thinking of trying a silencer but i wasnt sure how well they worked...and they are kinda pricey..

Yeah, resonators/silencers are pretty uncommon, so they are mostly hand-made, which makes them cost 3-5x the price of a muffler from the same manufacturer. The effect of one is also unpredictable, and you have to find a highly-motivated exhaust guy to get it to fit underneath a VX along with that monster PV of yours. Even if you find the guy, he will probably have to rehang the PV as well, so you will be looking at a full-price installation... $250 or more for the install, plus $200 for the resonator, and no one knows what you will end up with.

I'll say with confidence that you will like the improvement of the Dynomax, PB, both in terms of sound quality and level, as well as vehicle performance. I'm not going to say it anymore, though - I'm just a guy with the same problem/complaint as you who was 100% happy with this solution, which also happens to be the cheapest. Clearly, that's not much reason to consider my advice...

Good luck!

vehigaz-
no, by no means am i saying that your suggestion is not any good...in fact its the most reasonably priced, and the most proven....so most likely that is the route i will go...i just want to explore all of my options before i decide on something..

kenny-
yes you are correct...the infinity has a 1-to-2 then 2 smaller mufflers after that...i found that out after i already suggested the idea...therefore its not very likely considering with that much muffler under my car, one of them would definately get ripped off while wheeling

If you have the money and a welder at hand, you can go down this route. I've thought about getting one installed. I know a couple of guys that have a similar one that is controlled by solenoid instead of wire cable. Keeps it nice and quiet till you really want the extra airflow/sound...

Fair enough PB. Sorry - I didn't mean to sound like I was insisting you follow my suggestion either! Just painting a picture...

And just so I'm really clear - the Dynomax still has plenty of sound to it, but it's like 70% of the volume the FlowMaster put out. What you said about the PV - (paraphrased) that it sounds great at idle but is just a loud, obnoxious drone at highway speeds - I said about the FM that I hated so much. The Dynomax still has a better-than-stock sound to it at idle, but it doesn't fill the entire cabin with exhaust roar at cruising speeds....

I also would kill (and I have a list) for an exhaust that sounds a bit electronic like an FX, but the challenges are numerous to match all the exact conditions.

I think the biggest challenge is fitting the entire FX system under our truck.
I'm not sure, but I would guess the infinity FX would have a 1-in-2-out muffler. Things get more crammed if it so happens to have two mufflers...

Also I think we would be taking a bit of a horsepower hit with a stock FX muffler system.

Jack, for a quick "easy" fix, see about throwing on a glasspack resonator after your PV if you have room. I had to to quiet my magnaflow down, worked quite well... see my gallery for how I had to stuff those glass packs in right before the tips. I'm probably going to also add resonator tips for a bit more of a tone down, sooner or later.

I had a MorganTec 1-in-2-out and it was an amazing growl, but with no glass packing or flow blending it developed a huge resonation at 50mph. At 65mph, it sounded a bit like you were in a small plane... Fun for a while, but attracted too much "attention".
