Great news! The vibration sounds I was experiencing with the new d-pipe have seemed to subside.

I think maybe the system just needed a day or two to settle in. Hopefully the noise will not come back....

Anyway, thank you keepingitclean for everything you have done.

MEGAN ROCKS!

Nice

soccerbenk

woo good news!

Dtls

Damn, wish I was as fortunate as you, I still hear that horrible rattling.

keepingitclean

DTLS,

I thought you were gonna send me the info so I can send you a new pipe

Elementz

Just an update on my new d-pipe. Still getting a slight tinny rattling noise when I accelerate and turn at the same time.

It went away for a day or two and now its back, although not as bad. Its not that noticeable but noticeable enough....

The saga continues...

Dtls

Sorry, got busy, but I talked to Calvin and he sent it to me.

Dtls

I did a search about removing the heat shield on the cat and could not find many tlers driving w/o it. However one person said he had a similar problem and an Acura dealer did some kind of mod on the cat heat shield itself, claiming that Acura cheapened the material some kind of way solving the problem. I am tempted to remove the shield just to test. Has anyone tried this?

MikePA

A catalytic converter generates a lot of heat hence the shields which prevent things from catching on fire. I suppose a test would be OK but I wouldn't leave them off for long.

BLaCk Acc

anyone else put there new downpipe on? Been too busy and havent had a chance to put mine on.

Dtls

You sir are correct, it would just be a test for sure. The reason I thought about testing it briefly, is it actually has 2 shields, one that is mounted directly underneath the area of the cat, then of course the one that physically surrounds the cat itself.

mikelee223

I've had my heat shield off the cat for about 6 months already.. I havent had any problems. I took it off cause it started to rattle.

Dtls

Have you noticed any major changes? Does your center console seem hotter to you or anything else for that matter.

MikePA

Just don't park where there's any high grass or combustibles that could catch fire if they came in contact with the converter.

mikelee223

I havent noticed any heat changes.. But I guess its because the weather isnt that warm yet.


I would figure the whole exhaust would have the same temperature as the Cat. How would that cause a fire.

MikePA

I've always heard the cat runs hotter than the rest of the exhaust system.

mikelee223

That can be true.. But you go figure that from the header to mufflers. The headers should be the hottest part of the exhaust.

Elementz

Well, Im back with bad news...

The vibration and rattling noises are getting much worse since installing the new d-pipe.

I get a loud tinny vibration noise from underneath the car (it sounds like the heat shield on the cat. is vibrating against something).

I'm also getting a low, bassy vibration noise when I accelerate. Kind of like when you hear a good system rattling shit in a P.O.S. car but not as pronounced.

Anyone else experiencing this with the new d-pipe installed?

Looks like I'm headed back to the dealership......

MikePA

Bummer. Are you considering installing your stock headers or getting Comptechs?

Elementz

Not yet. But if its not fixed next time I get it worked on, I will start to consider other brands of headers.

I've already spent entirely too much money and time during this process.

I wouldn't be all that upset, but the original set of Megans I pulled off the car didn't sound as bad as this set. Not to mention the problem is getting worse. My car now sounds like a real P.O.S. Its embarrasing really.

I am happy that Megan is trying to werk with us, but this 'redesigned' d-pipe leaves much to be desired.

MikePA

I forget, did you buy them new or used?

I just got my new downpipe installed today. No change whatsoever, my car still sounds like shit.

What the hell do I do now??

BLaCk Acc

r u guys fuking serious??
I'm glad i havent put my new downpipe on yet, I wont even bother if this is the same response everyone is getting. Is the leakage problem still there too or just the resonance??
why the hell is it so hard to make some good headers?

moahdriven

my new downpipe fixed the leaking i had out of one of the gaskets, i do get slight vibrations sometimes but i think if i jus went back and had the bolts retorqued itd be fine.

could be the installation. ive given my muffler guy alot of business so he took time in making sure he put it on perfectly.

Elementz

Same here. Leaking fixed but the vibration noises are awful.

Elementz

These goddamn vibration/rattling noises are getting rediculous. They are getting sooo bad, I'm embarrased to even drive my car.

I'm going to try and fix it myself this weekend. If I cant, I will try the dealer one more time. After that, I'm gonna try for a refund......

I have no other choice.

BLaCk Acc

daym dude that sucks, how the hell do we get rid of this prob? What causes this resonance/rattling noise?? Is it so damn hard to fix? I still havent put in my new downpipe due to hearing all this I dont think it'll be worth it, maybe to just fix the leak ill put it in.

Elementz

Well, i fixed one of the problems this weekend (temporarily). It turns out that the bolts on the heat shield around the catalytic converter rusted thru and the heat shield was flapping around under there causing the tinny rattling noise. So that noise was not header related.

I wrapped the heat shield with duct tape real tight and it seemed to do the job. I know its ghetto but I'll have the dealership replace it with a new one next time I'm in for service.

However, I still get the low, bassy resonance sounds when accelerating. It really sounds pretty bad. I will have the dealership retorque the bolts and see if that helps.

BLaCk Acc

damn these freaking headers!
I worked my ass off to put the new downpipe in, i was glad at first because there was no resonance, but the leakage problem was still there. so atleast one problem got solved right? WRONGG, about 4 days later, resonance is back, only good part this time is that it goes away but is louder then before!! After i drive the car for about 3-5minutes it goes away, but everytime u turn the car on and leave it's sounds horrible at like 2.2k rpm and then once again at 3.2rpm , i dont know wat to do man! Some peeps have no probs with it and some dont, i guess i got the bad apple off the tree!!
wat the hell causes resonance??
Does a leak in the headers cause a hp loss??

keepingitclean

I honestly believe its an installation issue. No offense honestly but take it to a shop

*Striving, not thriving

sorry, can't help myself

BLaCk Acc

u know wat, i actually thought about doing that, and im gonna take it to my mechanic! BUT if that shit still gives me the same problems, im gonna throw that damn downpipe in someones face for fucking with my time and money!

is there any more word on this issue right now? after reading this i realize i have the same problem, but if no one is getting the problem solved then i don't know if i want to go through the hassle of buying a new down pipe.

Ice Man

To be honest I think that you should just request a different set of headers. I have the new batch and its been about a month and I haven't had any probs.

soccerbenk

well ive had my new down pipe on for about a week and a half yet and absolutly no problems

Sust Man

Does anyone know if this guy is still honoring warranty work or not? I PM'd him and no reply.
