Big Big resonator will usually tone it down. I used 36" of resonator on my old car almost the whole length. It was decently quiet for a 2.5 single with a fart can in the back.

 

Yes. The resonator is on and I added the vibrant after it. The vibrant was added right at that bend before the Y-Pipe. Its where that hanger hook was located. They cut that bend and remodded the bend with the Vibrant Ultra Quiet resonator and welded the hanger hook on it so it stays tight. I have to say they did a good job. It may not be stainless tig welded but it was still a good job IMO.

 

The guys at the shop wanted me to replace the original resonator with a longer one. They told me it would be quieter than my setup with the Vibrant but I'm glad I didn't go that route. Any quieter than what I have now would be a complete waste. The vibrant is clear completely through the resonator so when I smash on the gas I don't loose much from what it originally sounded like. At idle it still has that distinct tone but it's not as loud and on acceleration its toned down a little bit. I can listen to music at 6 volume with no problem.

On another note when I roll my windows down it still has a sweet tone. It's as if not much has left from outside the car but inside its a complete change. The Vibrant achieved it with flying colors. Listening to the video clip I have to say it captured the sound very well. I hope this helps you guys in your search.

 

Guys,

help. I just got the Exlr8 exhaust installed and all that, but now when I first start the car, I get a water under the car. Yesterday, I started the car again and got under to find that the water is coming from the connection between the test pipe and the exhaust pipe. The gasket is there. What could it be. Should I try tighten it more and se if it works? Or could it be the gasket it self?

 

If there is condensation coming out of there that means the gasket is either shot or there is no gasket in there. You can try tightening it. It might cure it but if it doesnt you need a new gasket there.

 

the gasket is there. I am not sure if it is shut though.

In case I need new gasket, where should I look to buy one. lol

 

Any update on the cone? i am still waiting............

 

^ Still haven't gotten mine... It's killing me too because I am waiting to see how your magnaflow muffler works out. C'mon Billy Boat.

 

Cones shipped today.

 

Do you have tracking numbers?

 

surely you jest. billy boat's service on this whole matter is an embarrassment. josh is the guy getting kicked over it, but it is billy boat at the helm.

 

OK i got the cone today but im a bit disappoint. as soon as i got it i went to my garage and checked to see if it would fit into the 2.5" opening in the magnaflow resonator. it was not flush at all. its obvious from looking at ankurs pics of the cone that mine is missing the bottom.

take a look at the pics.

J1N - yes that is pretty pathetic, but it can be built up with welding rod to get it to 2.5" just have the welder make one pass around the circumference of the cone with 3/32" rod. if you just tell him what OD it needs to be, he will know how heavy of a weld to lay. if he overdoes it, he just grinds it down a little to fit. after that, it ought to fit more snug. of course that will cost you more welding labor $$. it is not going to be seal welded to the inside of the pipe anyway. it will just be tacked in 4 spots, so gasses can still squeeze by the outside.

in all honesty, you could just leave it as is. the welder can span that gap with no problem. it's just like doing a root pass on a full pen weld. very easy for anyone that welds. you would just have more gasses slipping past it.

if you lived close, i'd fix it for you.

 

yeah, it is pretty pathetic. i called the shop right after i got it and tried to see if i could get it done on Monday since i have off from work (federal holiday). he told me they might be too busy to do it but there is this other place that i can get it done that's pretty close to my house but the guy there seems like a douche from talking to him on the phone. i'll probably get it done there if the other guy is to busy.

thanks for the info bout the welding. it would be nice if we lived closer.

 

Best of luck. Be sure to let us know how it goes.

 

update?

 

Sorry dont have it in yet. called one shop and they didnt have time on monday (i had off from work) and they wont work with me on doing it later then 5pm and they are only open on weekdays.

other shop just got a huge project and are really busy so the guy said he will call me when they have time. im going to follow up today and see if i can get it done this weekend. they on the other hand will work with me and will do it after 5 on a weekday.

 

OK i got the cone and magnaflow res on.

Found out that the XLR8 cat back is 2.5" OD not ID. the magnaflow res is 2.5" ID and it slipped right over the XLR8 when we cut it.

Also i had a leak where the first pipe meets the one with the Y. so what we did was cut the XLR8 resonator out and part of the other pipe where it gets wider to meet the first pipe. put the cone in before the resonator and MIG welded the cone into the first pipe. Then we got the exhaust + mag res dry fitted it on, MIG welded it in a couple spots took it down then TIG Welded the whole thing. so now its all one pipe till it meets the mufflers so no leaks.

The cone actually fit right into the pipe since its really 2.5" OD. so my bad on thinking that the cone wasn't made correctly.


Results!

i have to say the amount of vibration that i was getting before has gone down ALOT. i think that its cause of the cone. before i had no rattles but after i put the cat back on the vibration off of it would cause random things to rattle. center console would rattle sometimes, glove box... etc.

The drone is still there but not as loud as it was before. i would say it went down about 50%.....

Here are the Audio clips of before and after. if it doesnt work then let me know. first time trying to use this site to share audio clips.

Before: http://www.filedropper.com/ds20009_1

After http://www.filedropper.com/ds20012

 

So you now have the Cone and the new Res in?

 

Yup. I put the cone + magnaflow resonator in. Were you able to hear the sound clips?

I have to say that almost all the drone is gone. I’m a little more sensitive to the drone early in the morning and my drive this morning was pretty droneless. Most of the noise i hear from the exhaust is coming from the rear and not really at all from under the car.

The exhaust still sounds great from the outside. When we got the thing off the lift and fired it up it wasn’t as loud but it still sounded great.

There is still a little bit of drone when I hold it at 2k rpm but just regular driving around is ALOT better.

Couple things I have noticed though.
1. The cone creates some back pressure so when I let go of the gas the car doesn’t slow down as fast as it did before. before in traffic i didnt even need to use the brakes alot cause it would slow down on its own.
2. I feel more low end torque but less at the higher end. Also I’m sure a lost a couple ponies with the restricted air flow from the cone.


Overall I am very happy with the drone level / exhaust note.

 

Good to hear. I'm installing my CC insert tomorrow with the hope of reducing my drone problems as well. I will post results when I'm done.

 

Got the Car Chemistry insert installed today. Drone is not completely eliminated but definitely more tolerable. I'd say drone is down about 50-60%. There is some restriction, I don't have the pick that I did before but truthfully I'm ok with that.

 

Can you give me the link you found on google? I want to purchase the resonator too. I think the drone for the atlp base exhaust is too loud.

 

Will this resonator works with the Atlp base exhaust? I have a 2007 TL with the atlp exhaust and atlp race pipe, the drone is killing me. I hope this resonator work with the atlp. I talking about the magnaflow 10426 resonator. Thank you

 

Yes it will work with the ATLP. the guy that suggested the magnaflow res did it on his ATLP.

i got the magnaflow res from amazon. just go on there and do a search


update on the cone: do not add the cone... drone is way lower but the power is gone. i got so used to the extra whp and now its kind of annoying to have less. im probably going to take it out and add the ultra vibrant res and put the magnaflow res right behind the test pipe.

 

So you have the res on your car? Does it helps with the drone? I hope it does because I just ordered the magnaflow res and paid for 1 day shipping too. Yep, I am desperate!! Hope it will greatly reduce the drone inside the cabin. Vvroooom .... Thank you guys

 

yes it helps alot but it doesnt completely kill it. i also have the cone in mine which helps reduce drone. im probably gonna take the cone out tho and have the magnaflow move up right behind the test pipe and add the vibrant res back where the mid muffler goes.

http://www.amazon.com/gp/product/B000E3VHWI this is the cheapeset i can find the vibrant res

 

How much does it costs you to have the res installed?

 

should be around 80$. shouldnt take more then an hour. make sure they do TIG welds.

if TIG welds werent nessesary i could get it done for 5$ lol

 

What if they don't do the TIG? Can regular weld be done? And what is TIG weld?

 

the magnaflow resonator is here! Going to install it on Monday and i really hope it'll kill the DRONE inside the cabin or greatly reduce it. I"ll keep update on the progress for those who are wondering if the magnaflow would help. I'll find out the answer on monday!!

 

J1N, I added the CC insert and it did a great job of reducing the drone, but like you said, it did rob the system of some power. It's still better than stock, but it just doesn't have that "burst" that it used to have. I figured I'd just leave it the way it is, but after reading your post about adding a Magnaflow Resonator and a Vibrant Resonator, my interest has been peaked again. Let us know how it goes when you add both, I'm waiting with abated breath to hear the results!

 

A MIG weld will be fine which is what most shops do. If its done correctly the weld will not fail. Go to a reputable shop, or find a pro welder on your own, anyone can lay a weld, but quality is what counts here. TIG welds are the best weld IMO. They are the strongest (when done right) and the most beautiful for sure. It costs more and I don't think a TIG is needed. I've seen gorgeous stick welds that will blow away most MIG welds I see so I don't think you need a TIG. It's all in how it's done, slag in any weld MIG, TIG or Stick = a weld that will eventually fail. Go with the MIG weld

 

yeah if i remember correctly XLR8 said the cone only takes away 1 or 2 whp which is total BS. i feel like the jpipe test pipe and catback gains are being totally negated by this cone. Ever since i put the cone in the power decrease has been bothering me. my plan now is to add the vibrant and move the magnaflow up right behind the test pipe and then add pre cat deletes. hopefully this setup will kill the drone and decrease the amount of rasp when i do the pre cats.

 

BB tested the resonator cones and they only showed a very minimal loss and in some systems no loss at all. The cones don't really impede flow.

 

I just don't want to be so concerned with killing the drone that I end up killing the exhaust note too. I wonder if using two resonators would make the car so quiet that it doesn't sound good anymore. Right now the drone is about 80-90% gone and the car sounds great. I can live with the loss of power if I have too. The car doesn't press me against the seat when I hit it anymore, but it's still decent.

 

Just had my Magnaflow Resonator installed on my ATLP exhaust-
For those who are concerned of completely loosing the 'wonderful' exhaust sounds of the ATLP - DONT WORRY, NOTHING TO BE CONCERNED ABOUT ! It didnt completely kill the drone BUT it reduced it to a level that -- i just LOVE IT sooo much! Now, this is how the ATLP suppose to sound like. . . VrooOooOmM .. VroOoOoM ! and Oh, did i mentioned that i didn't feel a different upon acceleration? It didn't kill any power :-D

 

My butt dyno is going to have to disagree.

The power loss is bothering me alot so thats why im doing precat deletes. the extra res should take care of the rasp that comes with the precats deletes.

im happy with the way it sounds right now but of course that isnt whats bothering me.

 

ATLP exhausts are very good. i know someone with the resonated quads and there is almost no drone. its on a 3.2 tho so a 3.5 might have some more drone.

the noise of the XLR8 is more comparable to the graddy evo 2 than the ATLP. ATLP isnt very loud at all.

 

same here too - almost no drone but still with that sexy sounds. I'm just loving it!!
