My car never sounded like it until I had a spare cat modded into a straight pipe for occasional use. Obviously replacing the original cat will fix it, but I'm wondering if adding or changing a resonator for a bigger one will necessarily remove the bumble bee or not? TIA

 

I'm not too sure on it.. But I believe adding a resonator will take that noise away.. Or you could just add a glass pack..

 

i used to run gutted cat, and straight pipe, and just a muffler, and had SERIOUS bumble bee.

i then failed emissions miserably, so i got a catgo high flow cat, that eliminated a lil bumble bee, but not all of it.

i recently got a glass pack resonator and sounds VERY nice. motor is much louder than exhaust, and exhaust sounds clean and muscly, even coming out of a 1.6l d16z6 pos....can't wait for h22

 

run open header lol

 

A resonator will fix your problem.

 

Should I add a resonator, or replace the resonator in my stock midpipe?

 

my friend had that problem on his civic....he welded in a small glasspack as a resonator and it sounded MUCH better, sounded good actually. A nice thick deep sound with no buzzy annoying crap

 

i run open header, all i have is this whirrling noise... not sure what it is... makes this pshhh sound like a bird chirping when i let off the throttle though. kidna annoyin

 

replace the testpipe with a resonated testpipe.

worked for me... sounded incredibly deep and rumbly, not raspy at all. (with an Apexi N1)

 

Deng it, your car is broken!I hear that noise too all of the time, on Supra's, Z's, RX-7's, I think they all must have some major mechanical problems. Psshhhh.....(probably means the engine is going to die soon).

 

where can i get this resonnated test pipe ?

and does this resonnated test pipe have glass pack in it ?

 

buy my RS*R

 

isnt that a complete catback ? i dont need the whole exhaust man .. got a greddy evo (;

 

 

Well, my car is way too loud as is right now. I'd like to ideally get rid of the bumble bee & quiet it down at the same time. Now would adding a glasspack achieve this or should I consider adding a different type of resonator?

 

Amen to that!

 

 

I still have my buzzing like sound after installing my highflow cat ... the cat itself is resignator like shape ... but the Greddy Evo cat back pipe has a resignator as well ... should i just have that resignator (in the cat back pipe) cut and have a glass pack put in it ... will this defeat the performance increase from the highflow cat btw?

 

that is the answer. its really funny though...i have a test pipe non-resonated and have no bee probs. oh well, ill take it.

 

Thats cool man ... but i need to fixxxxxxxxxxx mineeeeeeeeeeeee (: please tell me someone sells the resignated test pipe with glass pack or somethinggggggg i need linkzz people ... need to bring my tegraaa back from Limpinnnn to Pimpinnnn

 

PLEASeeeeeeeeeeeeee help me kill these BEEZzzzzzzzzz hehe

i wanna keep a high flow style cat ... but need to muffle the beez nest! Straight Pipes less inclined to have the BEE tone then high flow cats ? i dont care.. ill put in a resignated straight pipe ... if you guys thing it will help .. i dont mind it being loud .. just the buzz kind of sounds raggidy at certain points

also as a side note .. ill do some of my own research... anyone know where i can find DIRECT fit straight pipes... i know http://www.testpipe.com anyone bought one of these and it fit perfect ? thanks fellas

I just fit a 24" glasspack in place of my stock midpipe.. here my conclusions.

- I need an aftermarket midpipe, because the stock one is a double piped piece of crap. The inside diameter of the actual pipe that flows exhaust gasses is probably 1 3/4 ID ...

- The glassback got rid of the bumble bee and made the car a CRAP LOAD quiter... But what I realized is that the bumble bee was actually caused from my motor. Ever since I swapped the head and put the header etc on, I noticed the intake had a mean growl from 2700-3200rpm, and since I put the gutted cat on, I couldn't hear it.. Well turns out I couldn't hear it because the exhaust was too loud. The bumble bee was actually that mean growl being audible on the exhaust side, which caused a bad vibration: bumble bee.

 

can you tell you lost any performance puttin the glass pack in ?

 

Hey neo, What all do you have on your car. what is the differnet between resonated and non resonated?
