BHR with DaveSport cat longevity?
So I have done a lot of research all over the web and discussed most details with my local forum but I am stuck between two choices on mid pipes. I turn to the larger group as there is a ton of info on sound and quality but I am interested in longevity of the BHR WITH cat. Here are my thoughts
- I like the idea of not throwing a CEL (have a series II so can't clear it) and limited smell so BHR gets a plus here
- I don't race it but may do a little track run here in there in the future. Should I be concerned with the cat blowing out?
- Its kinda pricy in comparison to the RB so the RB wins here.

Well, I read some more and found some good post. Only one guy appears to have had an issue with the DS cat and he ran nitrous which I will not do. Most seem to claim a lesser smell with the BHR with DS cat, no CEL, and no performance difference concerns. So all that is left is the money which I can figure out from here. Any input is still very much appreciated. Thanks

Um, perhaps there's some confusion. I don't see where RB offers a cat option at all. Their dual-resonated midpipe is catless. Besides being, IMO, irresponsible, catless rotaries smell bad which is for me a deal breaker by itself. I used a different metal-substrate cat, and so far, so good. The stock cat costs $1100. Even if the Davesport lives for a much shorter time, it's cheap to replace. The BHR resonator is sweet, btw.

I thought I covered that with this statement on our website;
The DaveSport Performace Catalyst has not yet been tested by BHR for long-term durability nor for use in racing or turbocharged/supercharged applications and no warranty other than that provided by DaveSport is expressed nor implied. BHR suggests the DaveSport Catalyst be used ONLY in naturally-aspirated, street-driven, RX-8s.

If the DS fails, I hereby release Charles R. Hill and BHR from any responsibility express or implied.
Looking forward to its arrival.

Yeah I am all sold on the BHR DS cat route. When I posted this I was just concerned about dropping so much money on the addition of a cat if people were having issues with it like some were with the RP super cat. The money becomes a factor when you start thinking 325 for the RB with no cat to 675 for the BHR (I speaking strictly numbers and not comparing the two). I agree its more responsible to have a cat and makes sense. I did read the disclaimer on the site and I think it will cover my needs, I was just curious if others had any time tested input on their experience that's all. Thanks for the replies. I will be sure to comment on my experience.

for what it's worth; I've been running a davesport cat in my custom midpipe for sometime now and so far it's held up great. (far better then my former RP cat)

Plenty of people have used it NA without issue, but it is not really high flow IMO. Even though it may be 100 cpi the overall flow area (diameter) is too small. The factory cat is big for this reason. It will however work well and meet the needs of most people short of a full out race NA motor.

The only catalyst currently thought able to unquestionably handle the rigors of the Renesis is the expensive HJS catalyst. With TeamRX8's help/encouragement I have been thinking about offering the HJS as an option, just as we do the DaveSport, but very few people seem interested in an $1,050 performance midpipe.
I'm already allowing for the header and matching mid pipe being up to $1725….
