I have WorldTours old exhaust....
Trubenz w/ 18" Vibrant resonator and TPV mufflers....stock cat....manifolds...

all summer i loved the sound....but now that I am driving further and longer they start to drone massively when they heat up....i recently took a trip down to ohio and i had to keep it under 80 mph to keep the people in the backseat from complaining about the drone....

he mentioned adding a 12" resonator behind the gas tank before the y....and my debate is will that lessen the drone enough or do i (can i?) fit another 18"....

i want the sound in the high revs and some in the daily driving range....but less drone...

if you guys could comment or even if WorldTour could put in his opinion that would be great...

I have a similar problem with the Magnaflow muffler and dual resonators. As a temporary fix I used an exhaust pipe expanding tool in each tail pipe with 2 petals removed from each. Took a bit of tuning to do this. Actually runs better in the low/mid range with some loss up top. But you can drive !!! Advance auto parts carries these as loaner tools for $20. Need to replace the bolt that comes with it with a 3 1/2 inch 1/2 in bolt and nut. Final fix will be a restrictor from Staintune (motorcycle exhaust company from down under) to fit a 2 inch ID pipe. They say it drops the sound 10db with no performance loss. Good luck, Stan
 
I have headers, opt'd y pipe, magnaflow res and mufflers and I get drone at about 80 mph as well. It doesn't sound as bad as what you guys are getting, but its there.
 
Stan,

i'm curious as hell about the exhaust pipe expander....what is this...and how does it change the drone...i wouldn't mind a little more low-to-midrange...i haven't been using the high high ranges much lately in a daily driving...but the drone...

i ordered the 12" vibrant resonator...i'm going to get that on this weekend...
probably in the same spot that WorldTour had it on his black svt (after the gas tank and before the split out to the mufflers...he said he noticed about a 15-20% difference....but he had headers so i'm hoping it will be enough...besides his supercharged svt is unresonated so how much of his hearing is left....that thing was loud...

Usually used to expand exhaust or intake pipes so that it fits. Example, you need to connect a 2 inch diameter to 2.25 inch diameter pipe. You take the pipe expander to open up the 2 incher so that it fits the 2.25 diameter pipe.
 
Add a Vibrant 12" resonator behind the gas tank, Thats what I did on the replacement exhaust and it was way better. Vibrant also makes a SQ (Super quiet) resonator that would probably work even better.

I'll try to take some pics in place. Give me your e-mail. Go to the Advance Auto parts web site. Its the medium one for $15.88 + shipping. It works !. Another option is a motorcycle baffle made by Samson. PN A-152 for 2" ID and A-151 for 1 3/4 ID. $29 each at www.cycleshop.com. They have other sizes too. I may try these to. Probaly flow more and you can tune them better. The suystem I have is just to open, got to close it up a bit so I don't lose my hearing. Want to hear my home theater for a long time. Stan
 
I think all that autozone stuff is a step in the wrong direction. All that set up needs is another muffler up by the cat.
 
yeah...lets not make our own AutoZone silencers...the 12" Vibrant is already in the mail....so we will see if that does it....if it doesn't i'll probably bite the bullet and get the SQ version...thanks guys...

pudmunkie what exhaust are you doing on your svt..

Vibrant resonator is being installed right now hope it does what it's supposed to...

Alex and this one chick in his POM class were studying for a quiz and I was asking Alex questions about his car, fog light mods, exhaust, etc.,etc. and she said something along the lines of, "Geez!!!...what is with these 20 questions". I think she just got her panties all tangled up because she was nevrous about taking her quiz, which as Alex already mentioned was "hard as balls".
 
man...its still loud as **** all that changed was the drone at 80 is gone...

i'm debating on whether to get the Vibrant Ultra Quiet version to replace the 18" bottle resonator....but i don't want to spend $100 if its not going to lower the low end sound...any ideas...i want to lower the 1500-2500rpm sound just a little....
 
dude i'm at school tomorrow all day...i drive the thing to school...
if you are there and want to go take a test drive....lets do it...

the second resonator lowered the highway drone only....its pissing me off cuz it was like $65 for the resonator and $40 for the guy to weld it on...

if you would like you can not only try Hanzo, but Han Solo, Hanz & Franz, Hands, Hans that guy from that movie, and Hans that guy from that tv show that i forgot :) :) i have heard them all....jk
 
I like hanzo, it works well!

Ill probably be studying like a mofo all day. How late are you there? Maybe we a can do a highway rip from whitaker to mich ave after my laaaaate class
 
if i finish this paper tonight....i'm free from 12:45-2:30 and after 3:45....otherwise after 3:45...

haha....this kid i know named Reed calls me Hanzo....he got fired from SEEUS for harrassing this girl he was escorting back to her car....he's also 28 and still working on his undergrad....
