BHR Midpipe
Who else can say they can see them selves in their midpipe? Hmmm

Hey Ray---how close to the trans does the resonators get?
I have been running the mazsport midpipe for a couple years now and have been very pleased with it, but I did have to add shielding because it is really close to the trans.
Would yall consider selling a midpiple shield as a package deal?
The pipe would not have to be shielded all the way around--only on approx 50% of it.

Not yet sure but we have it as a high priority.
For now, we are working on a few other things that are pretty cool and we are opening our own "real" shop. As it stands, there are three things about MazdaManiac's car that (still) make him happy and giddy like a school-girl; 1) The engine we last built for him. 2) His new starter motor, 3) His BHR Midpipe and prototype BHR Cat-back.His happiness and input greatly influence what we develop and my happiness influences when it is we do them.[/

thanks Ray--been thinking about doing just that and getting the front part of my cat pipe weilded on so I can have a better gasket. Even with the carbon ones I can still get a very small leak.

. Don't get my hopes up haha
Aaargh! Poking around the BHR website looking at the fuel pump kit for a winter project, I came across http://blackhaloracing.com/2010/09/1...pe-came-to-be/ which shows you starting with the Moroso added to the midpipe. As perhaps proof of the saying, "(self-defined) great minds run in the same gutters", this is a similar arrangement I came up with this summer on my own. To whit, from my vGarage entry:
"rx7store 3" pipe with Magnaflow 59959 metalic substrate high-flow cat and Moroso 94051 spiral-flow muffler/resonator welded in". (The 92055 has become the 94055 and the 94051 is the non-polished version.)
The Dave Sport was out of stock when I ordered it, so I got the Magnaflow instead. Unfortunately, in the preceeding pages of discussion I didn't pick up that you were gonna offer a cat version (I won't run without one). I bought the pipe used for $100, so parts came to $250 plus about $75 for welding and fitting (not exact, I also had a port-matched manifold installed which I had them do at the same time (no engine lift in my humble garage)). I was a happy camper right up to the point that you tell me that this will fall apart (unless the 94-series is better than the 92-series was). Aaargh!
I first tried it with the stock muffler and was amazed that the sound was only slightly louder than with the stock midpipe. With the Greddy SP-2 on as well, the sound actually seems better-controlled and more tolerable to me, than with the stock + SP-2. I suspect the BHR version will be similar in that one now can "tune" the desired sound level over a range of near-stock to rather brutal by the choice of cat-back. Winter projects include "second skinning" the trunk and floor areas of the car with sound deadening material, which may give what I want without going to an OBX or RB cat-back.
How long before you saw the baffle failures in the "first 7" pipes? Probably need to save my Christmas money for the BHR ...

2) 30-90 days.
Further, I have heard from a few of those first 7 pipe owners and a very close customer here in PHX (who was in the video we shot) that they believe the new version to sound better than the previous version. The way they described it seems to logically coincide with the use of larger-gauge steel and more solid welds. It has been desrcibed as a deeper, more "solid" tone, than the previous resonators.
I am also about to re-check my DaveSport cat now that my bad MAF sensor has subjected the cat to completely random max-rich (11.0:1 type stuff) dumps of fuel during all driving modes since I installed it 3-4 months ago. So far, I STILL get no 420 CELs and, now that I have replaced my MAF sensor, the car sounds smooth, drive like a dream, and doesn't stink anymore. I still have the same mass-airflow as I did without the cat, too.
Yes, I think the no-cat thing is of marginal, if any, gain - especially considering that DaveSport survives a high level of abuse.
