It's simply a matter of heat. Too much heat and it's toast. The Davesport would get welded into whatever midpipe you select. Whatever midpipe you pick with whatever resonators won't make a difference in the amount of heat you are creating.
Keep calm with a low EGT tune and you too can make it last. It's just hamstringing you with a mental barrier knowing that going too high will shovel the money you spent down the drain.

Well i have no mods no upgrades its factory. I recently had to replace my engine, but the rotary mech told me my cat was good. It has 126k miles with about 90k i know on the original cat. On thing is i have a slight hesitation on take off at times like a delayed throttle response. New engine, plugs, wires, coils. I got a new air filter to intall cause mine has oil residue on it. The only code im throwing is a upstream 02. Would either of those cause it?

Post #18 in this very thread! Amazingly hidden isn't it.
The RB meets several of them, but certainly not all, namely not meeting the rasp and failure points, as well as changing the tone of your existing or selected cat-back.
This is one of the points that I fail to see the arguement of "cost" as why someone wouldn't pick BHR.
Why?
Lets go through a few scenarios:
A) Have an OEM cat, buy cheap $150 straight pipe, install in place of cat. Get sick of the rasp and ungoddly noise over a short period. Reinstall cat to make the problem stop. You have wasted $150 and gotten no where. Or buy a different midpipe. Still wasted $150 to learn how to get somewhere.
B) Buy highflow cat for $350, install. Cat blows out in 200 miles under the rotary's heat. No longer passes smog, noise is raspy and drones like crazy, unpleasant. Put OEM cat back on or go to a new pipe. $350 wasted.
C) Buy a glass packed generic midpipe for $250. Glass pack melts within 2,000 miles, noise uncontrolled now. Get sick of rasp and drone, replace with another option, $250 wasted.
D) Buy BHR midpipe for $500, install. 40,000 miles later, you still don't have any problems, still love the sound. $0 wasted.
For A, B, or C, if your 2nd choice isn't a BHR pipe, then it's either A, B, or C again, and you are continuing the money waste.
We see it time and time and friggin time again, where people opt for something else to "save money", and in the end, they either finally buy the BHR midpipe (spending the money anyway, plus the cost of the first and intermediate pipes, effectively increasing the cost to get to the BHR pipe by 50% - 200%), or even worse, they return to stock, flushing the cost of the other pipes down the drain with NOTHING to show for it.
Frankly, it's mind boggling why people do this to themselves.
I'm going to have to agree with this guy, I installed my AP midpipe days ago. I will attest to it's raspy-ness. It isn't terrible but it certainly isn't the sound I want. I did read an absolute crap load of threads(and continue to do so) before purchasing it, and it seemed to me that the sound was mild enough to justify the savings. Plus I wasn't in the same position I am now, financially speaking. Now I honestly do wish I had saved a little while longer and bought the BHR. My next one I will certainly be speaking to Charles, as I have a buddy who just bought one with a cat, and has nothing but good things to say.
I have a question regarding the AP, though. Why does it come out raspy like that? Is it just the stuff they put in it? You can clearly see the mesh in the resonators, is it just that crap rattling around? Or is it something I can't even fathom?

Missed this question.
It's because the resonators are just basically like cones or bells, and taken from piston powered resonator design. BHR could probably talk more about the technical side of it. Has largely to do with energy and wave resonances, etc... The piston designs simply don't cut it under the higher heat (meaning higher energy) and completely different pulse length and frequency.
It's like taking tweeter speakers and trying to pump deep bass at 400 watts through it. Simply not designed for it.
Have the TurboX catted mid pipe on my 06 Shinka with 4 k miles on it with no problems. No stink from the exhaust, no codes set, but I have no idea if it will pass a sniffer test. Very high quality construction. Very pleased with it.

was wondering cuz with a name like turboxs and their company description this cat would be made to handle a turbo engine. but i wanted to ask actual ppl and not just go by what description says. for less than $300 this cat seemed a too good to be true for a poor bolt on wonder boy like myself lol gonna do some custom werk this summer on the exhuast, gonna keep the stock 2.5" piping and weld in 2 twin loop mufflers, got one on my mx3 and with vibrant high flow it sounds beast mind you its a knock off twin loop but still sounds great.
