Ya I figured that not being for FI or racing applications meant that it wasnt road race worthy but that it would hold up under the occasional autocross. Obviously I was wrong.

What is this legendary service you speak of? Fwiw, it's my birthday today.

 

FWIW, my Davesport cat has held up to three seasons of intensive, national-level autocrossing with multiple drivers on an '04 that clocks 210 hp on a Mustang dyno (custom tune). Not trying to pick a fight with Charles over his policies, just pointing out my experiences.

Are the newer cars known to run overly rich with factory tune?

 

Ok so I just got my mid pipe and now just before redline the rpm drop even under full throttle almost like a V8 missing...any ideas?

Mark

 

What does a V8 sound like when it's missing?

 

Are you hitting the gas cut...

 

Steady pressure on the gas pedal and then rpms fluctuate almost as ifI were pumping the gas pedal?

 

Weird, running fine now? sounds excellent Thanks BHR!

 

Finally took the plunge an put the order in. Can't wait to have more BHR items in my car

 

nicely done Figs!

 

Just dropping an update:
I pulled off the midpipe (as part of a clutch replacement) 23,000 miles, and about 1 year 2 months from installation. This pipe has been from RI to SS13 to OR and back, dealt with a pretty severe new england winter, and daily driving the entire time. My pipe has discolored to a dark gray, but not a single sign of rust. Still sounds and performs perfect.

 

Does the BHR mid-pipe mate up perfectly with the TurboXS cat-back without modification?

The stock mid-pipe that comes with the TXS doesn't dampen the sound much (way too loud at cruising speeds). Was thinking about getting the BHR if it's a direct fit.

 

The pipe does mate to the TurboXS without modification. Just be sure to use the rear gasket that TurboXS provides because their cat-back is 3 inch while the pipe is equipped for a stock cat-back size.

I do like the tones of the TurboXS with our midpipe as they are much lower more bass like tones with our midpipe.

 

I am interested in wanting to purchase this, but like to ask if it will fit my 2.5' Magnaflow catback?

 

If the Magnaflow is designed to connect to the stock midpipe. then yes BHR Midpipe will bolt directly to it.

 

First let me preface this by saying, Charles clearly stated his policy with regard to the DS cat, and I am quite happy with the quality of the BHR products and customer support. I did read where there hadn't been extensive track testing with a DS cat installed. Being hard headed, living on the bleeding edge, or whatever reason makes it clear that it was my choice, I installed the BHR midpipe with DS cat, then took it to the track.

FWIW I am driving an 09 model, and it seems there was one other 09 with the same type of issues. Perhaps its an overly rich factory tune, but I believe its more likely that the DS cat, while able to handle limited hard use in a rotary, i.e. AutoX, it is probably the sustained track use that killed it on my car.

This is what was left of the cat after roughly 6 30 minute sessions at Roebling last weekend. The cat/midpipe had seen approx 100 miles of street driving prior to this with no issues.



Again, to be clear, it was my choice to attempt this, and I am happy with the quality of the item I purchased from BHR. The only reason I post this is to save someone the trouble of trying this out on their own. DS cat + rotary + track = no good. I will be putting this midpipe back on minus the cat.

Chris

 

Good info.



The midpipe already looks pretty "minus the cat" in that pic

 

Yeah its seems the DS doesn't hold up any better than the others. Not a big surprise really.

 

My bhr balloons came in today two days early Thanks guys

 

I would disagree with this statement only because I burned through two RP cats with simple street driving and the occasional dyno day where as my DaveSport seems to be holding up just fine against everything I throw at it. (knocks on wood)

RX-8 + Cat + road course = dead cat. (the only exception here might be the HJS but have fun paying that kind of money)
That we already knew but I wouldn't want people to shy away from the catted version simply because guys who are on the track are burning them up.
The reality is, most people here will never see the track so I'd say the catted version is still a great choice for the vast majority of owners.

 

That's because what was left after the rotary assault and battery ended up further down the pipe lodged against the resonator, once I get that cleaned out, we should be good to go.

I'd agree with this for sure, there's a huge difference between running on the street even "spirited driving" vs sustained road course driving. I will just have to learn to live with checking the CEL status with my Ultraguage every startup.

 

Yes it bolts up to the stock midpipe just fine. Great will be ordering this soon

 

I took my ride in for service, and told them i noticed the car stuttering through acceleration. They told me I need to replace the cats, and parts and labor would be $1350. Does anyone have the midpipe hooked up to stock exhaust? If so, how does it sound?

 

Another member here (azlizard) has the BHR midpipe and stock catback, I've heard it and it sounds good. It's maybe a TAD louder than stock, not much at all. The tone is a little different as well, little deeper and sounds better than with the stock cat on for sure. No drone at all either. I say go for it.

 

I ran a SR motorsports catless midpipe with the stock exhaust for a long time. Eventually the packing burns out and it will sound like ****.

 

the right packing won't burn up, but a lot of people seem to be happy with the BHR one and that stands for something

don't be so hard on the HJS cat Jedi. Yes, it is expensive but it does flow like a catless midpipe without harmful emissions and smell. Somebody just dropped $3k on a pair of Bride Cuga seats/rails and everybody says "cool", somebody drops $1k on an ultra-high flow cat converter that lives on a rotary application and the same people thinks that's foolish, go figure ...

that said for a NA street car the DS cat is a great value, for FI or competition use then the HJS should be considered
