Last followup.

my issue has nothing, absolutely nothing, to do with the BHR midpipe

Thanks for bearing with me guys. Please see below:

Now to find out the best way to solve this issue lolol.

 

Exhaust hangers?

 

must have just been some tension in the catback? No joke since after i made the video... no more noise LOL.

 

Nice! I would have just sprayed everything down with WD-40. Don't mind the smoke. LOL

 

K just wanted to put the final result on here...the issue was the donut gasket (NOT the one provided by BHR)

Basically I had the TXS catback and had to use the large TXS donut gasket to mate the midpipe to it. When i sold my catback, i sold the large TXS gasket and the BHR oem gasket because i wanted to give a new gasket to the buyer. I ended up using the TXS 'small' donut gasket on the BHR pipe.

Long story short ... use the bhr provided/oem gasket. After close investigation, the TXS gasket is just slightly less dense that it collapses a bit when you tighten the spring bolts. This causes the flanges to touch and make squeaking noises as they flex against eachother. I ordered a new OEM donut and no noise whatsoever .. not even the slightest.

So for anyone who is experiencing this squeaking issue, check the gasket, make sure you are using the one Charles and co provided.

 

I apologize if this question has been asked. I searched before I posted this. Does the midpipe add any sort of a high pitch tone along with the bassier tone? I love the sound of a high pitched, high revving engine. From all the videos I have watched, it seems that only the bassier portion of the sound range is enhanced. Is this due to the microphone quality or is that all there is to the exhaust? I'm very interested in buying this product regardless of pitch, but I would appreciate if someone helped me out.

 

Compared to the oem car, the BHR midpipe enhances the bass side a bit, not much the high side. HOWEVER, it allows your catback to come through, rather than screwing with it like most of the midpipes. So don't listen to clips of the pipe you want, listen to clips of the catback you want, that are either on the OEM cat or the BHR pipe. Find a catback with the sound you like and it will stay true with the BHR pipe installed.

 

Your sounding like yoda on purpose right?

 

Thanks. I don't think that it'll sound like a fartcan so it'll be alright.

Has anyone had just the resonator welded to an existing MP? Specifically an exoticspeed midpipe....

Its a little too raspy for my taste.

Thanks.

 

I know the exoticspeed pipe is 3'', just wondering if anyone has had it done. I'm not to familiar with welding so not sure if the different metals will work together etc...

 

I took a straight midpipe and added a cat and the BHR resonator. Without the resonator, my older Greddy catback was brutal. The BHR resonator did a great job of taming the beast without a full castration. Count me very pleased.

 

Even the BHR midpipe is not a *true* 3" midpipe. The only true 3" midpipes are custom built without the less than 3" OE inlet and outlet connections. Otherwise all the 3" midpipes I'm aware of come with a 3" OD main pipe section fitted with 2.63" OE fitment end connections just like the BHR mp.

Apparently Moroso must have improved their Spiral-Flo resonator since mine hasn't failed or broken following two racing seasons. Pretty decent for $100 with easy slip-fit connections provided

There is also a 2.5" version for non-3" mp fitment

My BHR mid pipe + TXS catback sounds today exactly the same as it did when I installed it in 2011. I'd be curious to hear what the moroso one sounds like. The resonator TXS uses was murder on my ears.

 

Says the guy who flew all the way to Hawaii to rebuild my engine.....:Eyecrazy :

:P

 

It's very quiet, I was really surprised considering I have a full custom manifold with 3" outlet and true 3" system that splits into dual 2.5" tailpipes at the rear. I am always well below the 100 dB racing sound limit, like in the mid 80s to low 90 depending on conditions.

Not everyone is going to build or modify their own midpipe. The info is just there for those who will or do, or people who have a smaller near OE diameter midpipe and just want to improve it.

Calling BS on silly assertions and claims has nothing to do with whether or not I like the owner or the company products. If my postings either help BHR sell products or other people achieve their own purposeful goal then that's as much ok with me as the one's who don't know any better in either case.

 

For reference below...


Environment is a big factor. Having had one of those original 7 midpipes referenced by Ray on my 8 (Borrowed from Zelse when my OE cat clogged and I was waiting on a new one) for about 6 weeks and 3,000 miles, in the dead of new england winter with at least 2 daily pipe temperature swings from <20F to >1500F, that original resonator was breaking apart even within that time, leaving pieces of metal rattling around inside my exhaust can and the catback pipe before the bend.

How many miles have you put on yours? Or hours? or complete heat cycles? Not "seasons", since an autocross season might only have about an hour of driving total? (12 events, 5 minutes per event?) Saying "I've had it last 2 hours so far!" isn't really helping anyone achieve anything.

This is just another case of taking your single experience in a very very narrow view of operating environments and applying it to everyone else with all of their widely ranging operating environments. Hugely flawed. Just like someone buying a brand new car and a week later "It's hugely reliable! No problems yet!".

Having had both resonators on my 8, and experiencing significant failure on the standard moroso one in as short as 2,000 miles but having the BHR production one last 55,000 miles with zero problems under an even greater range of metal stressing conditions. I guess that doesn't mean anything, since I didn't drive it in your microcosm environment?

 

^ very good point...!

I trust and know that Charles is an honest guy. He goes through extensive research for all his products. The reliability of his products, unanimously agreed by most, if not all, customers proves and supports his credibility and business.

 

Its about 3000 miles of combined street use for data logging and more WOT use between maximum temperature followed by cooldown than the avg. street car will ever see. My only claim is that it has worked for me and I suppose every persons experience is their own microcosm. Apparently thanks are in order for all those extra words you're shoving in my e-mouth.

 

Not really, your history of attacks on BHR's products form all the words and claims that everyone sees you making. Continuing to repeat them maintains the claims for other application environments by implication if nothing else.

You aren't fooling anyone by asserting that it is all "only my car" when challenged. If you really only felt that it was only your car that it applies to, you would either not respond or include that clarifying information in your posts. But no, you leave that out and try to undermine BHR's products anyway.

There is plenty of evidence that the original Moroso resonator has durability problems, and there is plenty of evidence that Ray's solution to that works perfectly. Not a microcosm in either case, and perhaps recognizing that is what you really have trouble with here.

 

there's no attack, that again is just your own perceived microcosm. I suppose he meant "held" since the idea has been around forever and the patent ran out a long time ago.

If it breaks I'll come back here and say Ray told us so. Until then I can only report that it has worked fine so far.

Somebody else previously posted this alternative on the forum as well:

Spiral Turbo Specialties:

 

I'm at about 45k on my BHR pipe at this point.

My B&B pipe lasted maybe 15k with the stock catback before its note turned.

 

I have around 20k-25k on my BHR pipe. Still sounds the same

 

there's always the Helmholtz j-pipe approach as well
