I've recently installed the RV6 V3 PCD's and j-pipe. With the stock exhaust on my 2007 TL-S I get some rasp from around 3-4k rpm. Can I add another resonator in addition to the stock one to eliminate the rasp or should I replace the stock one with something bigger? Also, is a 4" diameter the max size that will fit on a 3G or would a 5" fit? Thanks.

 

keep the stock one and add an 18 inch resonator after.

ya know how I learned that?

I was wondering the same exact thing..Im almost considering ordering the 14" now but i am not 100% sure which one is best for sound

 

Interesting read but it doesn't answer the diameter question. Everyone just says "added a resonator" with only one part number given and no follow up as to whether it was tried and if there was any interference. It seems that the larger the resonator, diameter and housing length, the better but it would be nice to know how large of a diameter resonator will fit without hitting heat shields. It would also be nice to know how long of a resonator will fit downstream of the stock resonator. I live out in the sticks so the local exhaust shops don't stock stainless resonators which means I have to special order whatever I choose. Basically I get one shot at getting this right or have to eat the cost of my mistakes.

 

i was just going to ask the same question i am running rv6-v3 with pcd's and i hate the rasp i have the mid muffler delete and the magnafolw resonator, should i just add another resonator to the exahaust and if so which one do you think i should go with?

 

from that thread and from Richie himself.
and before you ask about the diameter, did you click these links?
if you have you would have saw this:



Also, Listen to Sonnick. As he plays around with exhaust all the time. He's constantly changing his set up to fit his needs.

 

ultimately, you shouldnt have removed the mid-muffler.
as you can run the resonators in series.
try out a long resonator.
if that doesnt muffle the sound to your liking add another.

 

I have rasp from my pcd+jpipe combo on stock exhaust but I barely drive.
I wont fix mine until I am ready to get a cat back.
but if I were to buy a resonator, today. I'd get an 18" magnaflow.

 

yea i was thinking about keeping my 14'' magnaflow and maybe just adding my stock one to it, but also like you said about wating till you get a catback exhaust because i mite do that and just get a res cat back and just add my mag to that one.....ill have to try something but i am one that hates rasp but i love the power gains

 

The factory resonator is a 4" diameter so everyone just runs a 4" aftermarket one. I guess nobody has tried a 5".
Is there such a thing as too much resonator? I had asked this in a different thread and nobody had an answer from experience, just guesses. I read on a different forum that too much resonator will take you from rasp, right through the sweet spot, and into drone. Is that true? My fear is that since I only have rasp from around 3200-4000 rpm that I'll wind up doing more harm than good if I put in too big of a resonator. I had my local shop put my car on the lift so I could get some measurements tonight. The stock resonator is roughly 18". It looks like there's just enough room for an 18" resonator just forward of the factory one. If we cut the factory one out there's room for one huge resonator (30"+) or we could move the factory resonator back a bit and fit in a 22" resonator upstream of it. If there's actually such a thing as too much resonator then the best bet might be to remove the stock one and upgrade to a Magnaflow 22". Decisions, decisions.

 

^its all trial and error.

in the thread I posted, they kept the stock and added an 18 inch res.
again, trial and error.
honestly, you guys are making it harder than what it really is.

PM Sonnick, He can help you. so can turbonut, opel, etc.

 

18" magnaflow is fine. it will fit perfectly on your exhaust. that's what i used and i'm very happy with it.

magnaflow#10426.

here's a link. send the seller a BIN offer of $59.99 shipped.

Thanks sharksbreath for helping these noobs.

 

are you running just the 18" or do you have the along with your stock? Also do you still have the mid-muffler in place

 

he has a catback.
i think the non-res atlp....brb let me check.

 

thanks i think instead of buying another resonator im just going to add my stock one back on with the 14" magnaflow that should take care of it

 

Im still not sure which one to order..should i do the 14" and keep my stock one or 18" and keep the stock one?

 

if you read this thread:
https://acurazine.com/forums/showthread.php?t=787693

it states that the stock midmuffler is retained while adding an 18 inch resonator.






really, how hard is this?

Richie recommended the magnaflow #10426.
Sharksbreath recommended the magnaflow #10426


do i need to hold your hands while you both cross the street?

 

This is why removing the mid-muffler is a cheap and worthless mod.
it might sound cool, but if you EVER decide to upgrade to PCD's or Jpipe, RASP city!


I am against doing the stage mods....dont do that stupid gay shit.

 

I have the same problem unfortunately... I did remove the mid muffler and have it in my garage but dont have the heat shiled anymore. My setup V3 PCD-V3Jpipe-midmuffler delete- stock exhaust.

What should i do to get rid of the rasp, put that recommended resonator in place where the mid muffler was, can it even fit....

just wondering....

 

i quit.

 

bukva, if you add 2 rubber duckies in place of the midmuffler, you'll get a quacking sound.
better yet, add some pizza with bacon.

you know what would make your car sound super sexy?
grab some whistles and line them up in series inside the exhaust piping.
as you accelerate, you'll hear all the whistles!

you will now be known as bukvathewhistleguy.

 

Go F. Y. S. wonder in what space u'll end up then

 

I contacted Magnaflow and here's what they had to say:
JP,
Since the resonator is a secondary muffler the larger the muffler the quieter the system will tone down. As far as to much resonator, it is a subjective. To much resonator may quiet the system down to much for you. The difference if you went with the 22” resonator would be a lot different because the mufflers is bigger. The rule of thumb is the larger the body of the muffler the quieter it is.

Thank you,

Based on this reply the only downside to adding a lager resonator is a quieter exhaust so the larger the better as long as we don't mind less exhaust noise. I'll probably go with an 18" and let everyone know how it works out.

 

i might do 18 as well..so would u keep the stock one in as well im confused?

 

no you would remove the stock one! the 18" magnaflow will take the place of the stock res

 

but what if you dont have the mid muffler anymore ??

 

from what i keep getting from all this is leave stock resonator and add another inline to relieve rasp... correct me if im wrong...

 

Yes, install an additional resonator in front of your stock one. My exhaust shop suggested moving the stock on back so that it's just in front of the bend and then adding an additional resonator. Or, if your welder is good they could just leave the stock resonator where it is and add an 18" resonator right between the stock resonator and the flange connecting to the third cat (or where the third cat used to be )

 

cool~cool... thanks...

 

^ are you getting alot of rasp with just the j-pipe with stock precat's?

 

I had zero rasp with just the RV6 V3 j-pipe and stock exhaust. Only when I installed the precat deletes did I get some rasp from 3-4k rpm.

 

^ Same here..let me know what you think of the 18" resonator because im still debating between that one and the 14"

 

for the love of god, just get the 18" one.

what is there to debate? the larger the resonator, the smaller amount of rasp.

what if you get the 14" one and you still have a bunch of rasp?

just get the 18" and you'll be cherry.

 

But what if I don't have the mid-muffler any moar?

:roflcopter:

 

gahhhhhh!!!!

 

i have 0 rasp now; and PCD's are sitting in my room waiting to be installed car is in body shop probably getting it on monday installing then... just for the record i have RV6 V1 j~pipe; 3rd cat delete and no mid muffler... so im pretty sure ill have some rasp once PCD's are installed... but every time i ask everyone seems to answer everything else but the question of will adding a second resonator take away any HP if so probably 1~2 right nothing significant?...

 

^it won't take away anything noticeable. don't worry about it.

 

just added my stock res back on inline with the magnaflow res and well it def took away that horrible rasp but it really quieted it down a little too much i wish i could have a little more growl but as for messing around with the exhaust im done putting money in messing around with the tone and just gonna wait till i can put some money aside for the true dual exhaust.......this stinks

 

do you have the mid muffler delete?... im assuming if you dont it might help (can someone confirm)at most another $50 mine was free and other shops told me $35...
