Still runnin long and strong here Ray... been about 2 years I'd say

Charles,

You and I go aways back and Im not bashing on BHR. BHR makes premium parts that are quality; theres no need to get defensive as your name and ethics stands by your products. You always stand behind your product and help your customers if they need anything. I guess Instead of "alot" I should of said several... Regardless I meant no disrespect as I drink the "BHR Kool-aid". Alot of my purchases are from you and my car has a few BHR products on it that perform flawlessly, but I felt it was appropriate to post my video because some fellow members have had the same problem. There is always going to be those that dont know how to tighten a gasket properly (i.e. even torque across both sides to ensure a proper seal, not talking about you Paimon) but us that actually know how to install something (a midpipe has to be one of the easiest things to install) and for us to still have the noise its a little frustrating considering this resonator should last forever due to its design; So I guess I too should apologize for my frustration.

Nonetheless my BHR midpipe has always made this noise and until recently hasn't been a problem, but its started to get worse. It used to only this this noise when RPMs fell from about 2-2.5K to idle, but now there is a consistent rattling noise at idle that others have described. If there truly is a problem and after meeting you and talking to you over the years on the phone I know you would want to get to the bottom of this, hence my post.

This midpipe has been fantastic; Craftsmanship is fantastic, the welds are quality... literally no major complaints but the rattling noise needs to be addressed (least on my car). I realize statistically speaking there will be a few with defects that you will have to assess and repair/ send back... Please let me know what you find out as Id like to find a way to fix this problem on mine... Im not worried though Charles and you always take care of me and your loyal BHR customers... Ill give you a text or a call in the next week or so and chat it up with you... :rolleyes:

Alright well i took off the midpipe yesterday and did some inspecting. The pipe itself has no visible wear, corrosion, or irregular discoloration. No cracks, no holes, nothing. Took a look inside, nothing loose, nothing broken, and the internal welds of the resonator are nice and clean and still rock solid (didn't really take time to look at them when i first got the pipe, but wow, what a stellar job on the internals).

Anyway. the rear donut gasket is still in good condition, no crushing, no fraying, nothing. And the front ring gasket was in good shape.

O2 sensor is in there nice and snug, and torqued to spec.

So I am back to square one in trying to pinpoint the source of the noise. I was VERY VERY meticulous this time around when installing the pipe to make sure that i torqued down the manifold flange to make sure the ring gasket was in place, and that it had a nice flat mating.

Will report back in a few days.

The verbosity is as exemplary as the customer service. Energy doesn't just disappear. My own experience is that one set of vibrations is exchanged for another and what you're likely hearing is something else vibrating as a result of the exhaust sound being mitigated.

Just out of curiosity, Charles, is there any particular reason that the manifold side of the midpipe doesn't have a lip for the ring gasket to seat on? I noticed the OEM one had a lip (similar to the one on the midpipe outlet end for the donut gasket) while the BHR one instead has an inset like that of the exhaust header. This is nothing more than curiosity, not an allusion to anything related to my noise 'issue'.

This is more likely my "issue". Basically working my way from front to back on the entire exhaust to locate the source of my noise. Probably a component that i forgot to torque down somewhere.

I recall a post a few years back about a guy that was trying to find this rattle. He could only hear it while no moving at a certain RPM above idle, and it was driving him nuts. Finally he had his son stand next to the engine in the garage, and told him to point at what is rattling. He fired up the engine and brought up the revs to the point he could hear it, and his son pointed at the cabinet on the wall. :D:


Not saying that's it's the cabinet, but make sure it IS the midpipe you are hearing. :)

HAHA that is great. Yea I need to get my gf to help me out on this one, I tried to be very careful in my posts here not to insinuate that it was the midpipe, but moreso just a 'i will start here first' type of thing.

Is this still a good midpipe even with the built in cat or would i be better off without the cat?

just as good with a built in cat for those with daily drivers. Just be aware that if you use the car for racing it isn't guaranteed that the catalyst won't break down.

or weak/failing BHR coils, or any weak/failing coils regardless

your point in life is to just aggravate people isn't it?
quit being such a child...
constantly imposing on other's to stray away from companies or products you personally don't like, gets real tiring.
If there's a market for the product they sell and it works, why is it your need to deteriorate the companies credibility?
Team, I may not know as much about you in any circumstance about cars and their dynamics, but I do know when someone is acting like a little bitch like you constantly do.
Quit making your mission in life to piss people off, there's a certain way to talk to people whether it be da interwebz or not.
go back to blowing transmission's, your e-penis isn't getting any bigger.

my post is entirely valid and makes perfect sense to anyone with a basic understanding of ignition coils

that might not be you though ...

I do understand it's valid, but everyone knows captain obvious, you don't have to to point it out, you post just undermine others.

any coils that are weak won't perform regardless, but you have to mention a company to deliberately annoy them. it's how you say things that makes you come off rude.

anyway fuck it, this is about a midpipe, not coils. forget it.

My post explains the not so obvious for people who don't know any better. It has nothing to with undermining anyone and it wasn't me who brought the subject up here. Your replies seem misguided in general, and your first reply violates the forum rules. If you think there's a problem then that's what PM and the Moderators are for.

:dunno:


however, I can always appreciate a good dose of irony. :)

Team's avatar does say he's the love king.

it has more than one meaning

That Ray thinks he controls anything here is the crux of the issue. This is an open forum area. For an area he can control he can buy a dedicated slot in the vendor area like all the others.

Well that didn't take long. It was a nice peaceful week, but like so many other things it didn't last or have the effect many hoped for.

Why are we even having this discussion? Because you can't let anything I say go without thinking you can some how "address it and make the situation better" or rather just try to pile it on more like the post above. I made a simple innocuous statement that could easily have been ignored rather than making your own childish post about how I'm a child or beating me up for the thread going off subject when I didn't take it there but you all did and still are. You're all your own worst enemies and Ray himself is the biggest instigator of the us vs them/him/her drama on this forum. Its funny how he wants to cuddle up and act friendly with me when it involves doing the same thing to someone else, like when he had his man-divorce from MM. He started with all that same vile hate stuff like I was somehow going to embrace that ridiculous BS and I told him to buzz off because regardless of what anyone else thinks about me, I don't think that way about anyone else. I kept the PMs because I still can't believe anyone is that whacked out about hating another person, just as he has openly shown against me across the forum these last several months. You people don't anything near what you think you do about him, me, or anyone else here. A difference of opinion is only that. Its not the end of the world or somebody out to get you or hate you over or any other such nonsense.

Don't want drama? Then don't dramatically go about creating it

Charles , you know I am a supporter of your fine poducts and your professionalism.

Perhaps if this group of owners who have brought the BHR midpipe are having problems, maybe you can install a few midpipes on your own test RX-8 or your own RX-8 and see if there is a problem or not. It could be a bad batch from your supplier, it could be the owners themselves installing the midpipe incorrectly, and it could be something totally unrelated, as the stock cat came apart and is stuck in the muffler system and is making this sound.

Before I installed my aftermarket RB exhaust , some chunks of cat that broke off, got stuck in the stock exhaust , and it too made similiar sounds that was presented in the video.

Heat making contact with metal will always create strange sounds too, I was thinking the resonator part may be weaker metal and with the extreme temps that the rotary produces , it could have broken the filament inside. Etc.

Just trying to throw out suggestions as to what it may be. Maybe you can track when people started to notice the sound, like I mentioned earlier a batch of midpipes that was manufactured poorly could of left your store unknowingly.

You might need to put up a DIY vid on your site too , to properly show people how to install the midpipe. Everybody is not seasoned on how to wrench like you and I.

All this ends now.

All future comments, will directly relate to a BHR Midpipe and only this midpipe.

back to the topic at hand... so I haven't had a chance to really sit down and investigate the noise by actually getting underneath it and listening while someone manipulates the throttle, but, looks like my meticulous reinstall didn't do much to remedy the noises. The crummy part is that now that the weather is nice and i have the windows down, i can actually hear the noises echoing off of cars as I approach a redlight or coast down the street towards a stop sign.

Again, for those who are tardy to the party, this is not an indication of a faulty midpipe or anything, it could very well be something else. Just leaving as much detail as possible here in case others look in the future.

Will report back once I get underneath the car and poke around tomorrow/saturday.

So i recently placed some window flashing on my heat shield above my midpipe because i noticed the stock material was missing. No more more noise for me...i believe my noise was in fact due to unrestricted exhaust and resonance changes. You may want to give it a try if you notice that insulating material is missing. Thanks again Charles for a great product. Don't become discouraged! Its hard to find reputable, honest people who make such outstanding products anymore.

Following up again on my previous posts. Looks like the noise I am experiencing could actually be a squeaking where the outlet of the midpipe and the inlet of the exhaust mate. I noticed this weekend that if i get under the car and wiggle the mp-exhaust flange side to side, i get some faint squeaking noises.... i can assume that this noise is further exasperated by a naturally vibrating exhaust system. The fasteners are all torqued down to spec, and I am using the OEM springs for the exhaust (since i am using OEM catback) ... hrmm.

Hi,
Old springs?
Maybe springs are fatiqued?
