is it normal to hear lot's of metel cracking sound after the new ypipe was put on so that the new ypipe can settle in it's new location?

 

Not on mine. You might wanna check and make sure everything is okay.

 

not good.... may be the word " cracking" is not good choice of word.... just metals rubbing each other once in a while... and at certain RPM giving gas make the pipe vibrate alot....

i guess i need to take it back to the place where it was install and recheck it out...

 

the vibration that you are most likely experiencing is an exhaust brace rubbing the y pipe. the aftermarket sits lower and hits the first brace. you can either remove it completely or go to a hardware store buy about a half inch longer bolt with about 5 washers per bolt and put the brace back up. taking it off completely wont hurt but i figured it was on for rigidity purposes so i lowered mine.

 

can u explain this in more detail? or PM plz thanks...

 

sure. if you look under the car in about the middle of the car, there is a black exhaust brace. its main job is to keep the pipe from hitting the road if it ever fell. there are four bolts on each side. if you arent lowered, you can actually take it off without jacking or ramping it. i think its a 12 or 14mm bolt. take it off completely and leave it off and the noise will go away. if you want, take one of the bolts to home depot, get the same grade of bolt just about 1/2 inch longer and about 5 flat washers per bolt. so 8 bolts, 40 washers later you put the bolt through the brace, put the washers between the brace and the body of the car. do the same on all sides and you should be all good.

 

hummm I hope I can explain that to the installer. but i'll go get those parts and try to explain best I can but those parts are not really needed right? because if we can't figure it out we might as well just take them out so it don't vibrabte teh whole car.

 

it would not take you longer than 10 mins to drop the brace. you dont need much. unless he would do it for free and you feel like bringing it in again, you should be able to it just about anywhere. very simple thing to do and you might feel better knowing you fixed the problem.

 

You guys are talking about 4th gens right? b/c I just installed a Warpspeed Y on my 5th, and I'm having the same noise/vibration issues...

 

i dont believe the 4th gens have this brace. i could be wrong though. we were talking about 5ths.

 

I didn't see a brace? The only one I saw (and removed) was the one which the stock Y was connected to, which was bolted to the tranny case. The only brace I see that goes across that "tunnel" or "channel" is much farther back?

 

that is what i thought to when i saw the y pipe that was taken out it has those heat shields and braces all welded to the y pipe and on the mid section where there is a metal that is suppose to hook up to the rubber housing. it is not bented and long enough to reach the rubber housing and it is only vibrating alot when at low speed and not at high speed also i'm hearing sounds like when you are grinding your teeth together kind of sound when turning and going over bumps and when i'm stopping.

 

there is a thin gray brace towards the rear, i think it has only has 2 bolts. if you dont have a black brace connecting both sides of the car, chances are they took it. mine was put back on and the pipe would slam into the brace and just vibrate like crazy. when the engine moves back it pushes the pipe down and it just sits on the brace and shakes.

 

finally got it to stop vibration. i just figured out what you were talking about but i just inserted some heat resistance material b/t the black exhaust brace and the pipe and it held the pipe nice and tight and the vibration is gone. but i'm still trying to figure out how to connect the y pipe to the rubber housing. other then that i'm just need to stop by the track and test it out and see if there are good improvement. since there is lot's of debate on 2k2 if y pipe is really benifical or is b pipe benifial

 

Do you feel noticable gains?

 

im not aware of a way to make the aftermarket y pipe fit to the stock hanger. the designs are just different.

 

I actually installed the Y-pipe myself (with help from some local .orgers). I followed the instructions, but didn't see the brace you're referring to. As for the bracket that goes to the rubber bushing, there's no way to bend it. That piece is welded on. I'm going to call Warpspeed about the problem tomorrow, and recommend that you guys do too...

I definitely feel a hp boost, but the noise/vibration doesn't seem worth it...

 

just looked outside and the brace sits right between the cat and the resonator. blubyu2k2 had the warpspeed y and b with the same vibration. i removed the brace and 95% of the noise went away, the rest was the b pipe tapping on a heat shield. if theres no brace between the cat and resonator and theres still a violent vibration then im at loss for what it could be.
