Well, that's for a glasspack, that you're referring to, I think. Morgan, thanks for that...
I'm looking for the best rasp reduction out there...if it's 1 huge long resonator, so be it, if I can achieve it by getting 2 of the same dynomax's great.
I actually saw a cherry bomb brand one that's only 12" long last night, not sure if that's a good idea or not though.

in my personal experience dynomax cleaned up the rasp better than magnaflow...

go through my exhaust thread, sonnick and IHC have mentioned how to calculate sound dampening quality of a muffler (not resonators as I wasnt going to use 1) but it will give you a general idea

I dont have much experience with killing rasp as I dont have any, even with my 3" exhaust. Im running Magnaflow everything.

Hmmmm...so is that the secret? magnaflow everything?!?!
Thanks Anil, I'll look into that...

From my friends with mustang days, this brand came to mind...I wonder!?!?
it's meant for imports

+1 for dynomax

iTrader: (6)

^^yeah, you think the 2nd dynomax will shut this fkn rasp up once and for all?!?!

Of course, the HUGE magnaflow, that's 30" long in one shot is $32 shipped
The Dynomax's are $52 shipped...

Not a big deal, but I'm thinking the 2 dynomax's together will work, of all the "stages" of exhaust we have...the Dynomax was the only one that added a tone that I liked...stage 4 with just the magnaflow added rasp by just replacing the OEM resonator.

That's the other thing, I could just have them weld my oem resonator back in, but if I'm not happy I'll be annoyed that I paid to have it welded in and have to cut it out.

Steven!!! I DID work and went jogging today and played a little call of duty...in reference to the car, alllz I did was research!

Andy, thank you so much for sharing. I'll do some research on that, but I'm guessing that this is meant to KILL any and all forms of rasp the best! Thanks man.

Now, to decide, ultra quiet resonator, or the traditional one?! Traditional one looks to have similar specs to the dynomax/magnaflow etc...

Also, do you recommend putting it in in addition TO my dynomax? or replace the dynomax with it?

I'll come back when I know what we're talking about.......

not knowing anything on subject stops very few people on AZ from posting incessantly on said subject. Just fyi in case you wanna keep your posts up in here!

J.

I think I've decided...I have crappy welds on my stock piping/dynomax resonator, further worsened by my self applied exhaust leak fixer stuff...looks like I have clay all over every seem. I'm going to have a shop cut me a new length of 2.25" pipe...with no reducers and/or collars...and weld in the vibrant ultra quiet resonator. If that works, great, if not, I'll immediately have the shop transfer over my dynomax resonator in addition to.

Undying Dreams

iTrader: (3)

I just have no idea what "Stages" mean or what causes rasp. From reading it looks like the PCD (and HFPC?) make rasp. Does the V3 J-Pipe add rasp on it's own?

When it comes time to do exhaust I want it to sound like yours but without the rasp lol

iTrader: (5)

I do agree with Andy as well....never used Vibrant resonators but heard they are pretty damn awesome and a tab bit pricey with a limited selection of everything....

J, the best way to buy is @ Summitracing dot com.....their search filter is just awesome !!!

rockstar143

iTrader: (6)

Hmmm...good tip, thanks Anil...I bought my old lug locks from there, actually.
I may end up jumping on it at amazon though...a bit cheaper and free shipping.

Undying Dreams

iTrader: (3)

Summit is expensive as F.

iTrader: (5)

^^^ they price match and have free shipping

just call them and tell them you are getting it for cheaper on Amazon and they will hook u up !!! i did that with my muffler.....was 110 shipped and i got it for 90 shipped

the reason i asked Jer to go to summit was for their filter search....the search is awesome....so you can pick the right product and then see where you get it cheaper and either order it from there or call summit and order it from them

iTrader: (6)

Gotcha, good tip! Thanks man!
Yeah, we have amazon prime so at $85 with free 2 day shipping...hard to compare!

NOW you got me thinking with this inner volume thingy...I wonder if it'll kill the rasp with JUST the ultra quiet vibrant...I would like to try and just run this, and no dynomax...and if need be, add it to it right away.

J.

ebelp

I'm a n00b on this also. It seems there is some ongoing debate as to what each "stage" consists of. Are there any threads that elaborate?

swoosh

iTrader: (5)

^^^ I think Mike from ATLP had an awesome post with vids....I havent been able to find that thread....

the stage mods is only for increase in sound and if i remember correctly this is how it goes:

Stage 1: replacing the stock resonator with a straight pipe and the mid muffler stays as is
Stage 2: replacing the stock mid muffler with a straight pipe and stock resonator stays as is
Stage 3: replacing the mid muffler with a straight pipe and resonator with a dynomax/magnaflow resonator
Stage 4: replacing the mid muffler and the resonator with a straight pipe

and recently people have been calling this the
Stage 5: replacing the mid muffler and resonator and both the mufflers with a straight pipe....so you have no mufflers and resonators but only the exhaust tip.....

rockstar143

iTrader: (6)

I was actually trying to find that thread today...
Didn't...
Submitted an "Offer" on ebay for that vibrant for $75 shipped...ends in 5 hours so we'll see! If not, I'll pay the extra 10 bucks and buy it on amazon. Whether I do just the vibrant or the vibrant AND the dynomax, I'm sold on giving the vibrant a try.

I'll have a stage 69...that's what I'll call it.

I think Anil is close, but I think stage III is dynomax and stage IV is magnaflow. And stage 1 I think is reversed...no mid muffler, but stock dynomax...something like that.

1 is the midmuffler delete
2 is resonator swap
3 is either the other resonator or 3rd cat delete or muffler swap
4 is removing all the sound cancelling for straight pipes and that sounds like assholes playing a bugle.

Undying Dreams

iTrader: (3)

Hahahaha thanks Anil and Sean!

veggiemonster

iTrader: (1)

we all slightly disagree, but I think thats actually a great rundown lol. there's different 'versions' and eveyrone seems to call them something different

swoosh

iTrader: (5)

^^^ true....also that is how i remember it....i might be wrong over mixing up stage 1 and 2....but the basic idea is:

Stage1/2: instead of having 2 muffling devices (resonator/mid muffler) in the down pipe you replace 1 with a straight pipe....so you have 1 stock muffling device and 1 straight "piped".....
Stage3: is like the stage 1/2 which is having 1 muffling device, but different as that device is not stock but instead a magnaflow/dynomax one
Stage4: is straight piped, so no muffling device
Stage5: no mufflers....so you not only straight pipe the downpipe but also the exits....

now someone will come up with a stage 6 which is having 1 muffling device in the downpipe and no mufflers and if it sounds really good, everyone will want a stage 6 LOL

Undying Dreams

Nobody answered the j-pipe question, does it alone cause rasp?

veggiemonster

iTrader: (1)

pulling cats will allow more rasp potential. always. they muffle just as much if not more than a stock resonator does. If you are running all cats and a resonator swap and a mid muffler delete, and you are close to rasp, the j-pipe will more than likely put you into 'rasp territory'

it's not a garuntee (that's not how you spell it is it?)

swoosh

iTrader: (5)

Yes and no....

when you have a free flowing exhaust rasp is created....as you are giving exhaust pulses more room in the exhaust pipe....hence the exhaust pipe diameter is so important....

when you have no backpressure, rasp is created....

so if you have your stock cats, aftermarket jpipe and stock exhaust, there will be NO RASP

if you have PCD's and stock jpipe and stock exhaust, there will be little rasp....
now if you open the exhaust up a little more, so PCD's, aftermarket jpipe and stock exhaust, a little more rasp
finally if you open it all the way, you will have more rasp....

but there is a solution, RESONATORS....hence you will see exhaust like RV6/XLR8/ATLP offering resonated and non resonated versions....so if you have stock cats, get the non resonated version....it wont have rasp and it have a deeper growl.....if you get the resonated version with the stock cats, you wont be able to hear the exhaust as much.....

and if you have the PCD's then get the resonated version so it will muffle some rasp.....

hope that makes sense....

Undying Dreams

iTrader: (3)

That makes a lot more sense than what I have read. How loud is the j-pipe? I don't want it to be obnoxious, just want a nice smooth tone when it's idling and normal driving.

As far as exhaust I just wanted to go with the j-pipe but if that isn;t enough I would consider PCD.

swoosh

iTrader: (5)

^^^ well i rode in Steven Bells Type S after I installed the RV6 V3 jpipe....all other exhaust components were stock....and damn it sounds awesome....

there was no sound change at normal cruising.....but when you hit WOT, it sounded just awesome, had a little growl but nothing too loud....

now if you add PCD's to this whole thing, hello RASP !!!

Undying Dreams

iTrader: (3)

So if I was looking to keep things stock except a j-pipe and PCD's then I would need a resonator? Correct?

swoosh

iTrader: (5)

keep the stock exhaust as is....and then you can replace the stock resonator with a vibrant/magnaflow/dynomax resonator to suit your sounds needs.....

Undying Dreams

iTrader: (3)

Thanks I'll probably just end up with a j-pipe. The other stuff is super expensive.

^^^ look into the stock type S primary cats....they are high flowing (than stock, not as high flowing as the RV6) but you can land a sweet deal on em....check out the BM, i know someone was selling it for 200 something....and then get the jpipe and you be in biznizzz

Undying Dreams

iTrader: (3)

Whaaa!! Thanks! I'll look into it, gonna ask the dealer a few questions coming up. They've sent me a coupon for the 105k service for like $400...gonna ask if that's IT or will I need more, gonna ask what the hell they detailed my car with too, it smelled so effing good when I picked it up.

veggiemonster

iTrader: (1)

on resonator vs muffler talks...what do you want it to sound like? each has a purpose to the end sound, both cut the nasty rasp. but resonators will 'smooth' the sound more than a muffler, a muffler will sort of just limit the high pitch shit, and leave the aggressive 'warble' that a v6 has.

then you decide if you want deep or a little more tenor and that's how you decide what brand/size/design of muffler and or resonator you want.

with cats, or say with turbos but no cats, you don't really need a resonator, since cats and turbos act like them already (in how they modify the sounds)

but if you go full catless you'll be using two mufflers and a resonator.

or gimme like 150, I'll send you mine, and you punch them. that would be better than type-s cats
