I don't perceive that reading comprehension is strong with this one. There are recommendations already posted.

You want a real measure of a product? Don't look for people that just bought it. Do searches in the FS section. See why people get rid of what they buy, and how often. See how fast they are sold. BHR's products are sold faster that anything else in the used parts section for a reason. There are also not many people willing to part with them.

You can't waste money with a BHR midpipe, you probably will with the rest. It's entirely worth the money.

I really want to do some mods but a CAI would be pointless to me
Since the 8 has one of the best stock intakes.
I have the RR catback single(2hp), thats about it to the engine though :/ Every other mod necessitates more $$ to throw at it to become worth while.

I believe teamrx8 has a good highflow cat but it was well over $1500.

It really depends what you want to make a recommendation for you. Like i said before, if you want something insanely loud get turboxs, same sound as having a cat then get bhr, cant afford bhr then get RacingBeat, living off food stamps then get the AgencyPower.

And yes you get flames, but dont expect massive fuel dumping rx7 flames, we get more sudden bursts of sparky flames that shoot out. rx7 flames are much more.....elegant.

Wow s13torx8 you post insanely quick and it seems as if you're not even comprehending the responses. Let just say if your living off food stamps and dont mind an annoying rasp then you'll love that AP. I had the same pipe and removed/sold it a week later. If you want something more quality you have to pay up. You're driving an 8 now, not exactly cheap parts compared to a 240.

Which are the CEL codes that pop up when you install a catless midpipe ? I'm getting my BHR midpipe soon and will mask them with my AP.

My RP midpipe is garbage ... I believe the single resonator is toasted as you can hear something rattling around in it but nothing comes out.
I'm guessing the glass pack is all broken up?

I'm sooooo going to get a BHR midpipe.

Yeah I was on my phone because I was at school and then work. I wait til I get home to check back and check all the links and most of the comments because it is a lot easier on my computer. I'm not living off food stamps haha just on a college student budget. But my friend has the AP and he loves it and I have also heard it so I thought I'd give it a shot

The ap with the stock exhaust gets a bad resonance to it around 4k rpm for +/- 500 - 1000 rpm. The sound only gets worse as the midpipe ages and the packing gets eaten away. I have never looked in it since I installed it but you can tell somethings happening down there. I have noticed a difference in exhaust sound over the time I have owned it it just gets louder.

In think no matter what you are going to get a raspy sound with any exhaust and the ap midpipe. If you are ok with that then you should be happy with it when you get it on there.

I'm not aware of many street legal cars driving around without a 'full catback system'. Even a bone-stock car has exhaust routing hardware from the rear of the cat back to the tips.



Just make sure you eventually come back to these threads to apologize and admit you were wrong for ignoring the constant advice once you realize why people complain about them, and the only good reviews you are seeing are from people that JUST installed them (and they haven't had time to fail yet)

I just didn't want to spend 500 bucks on a midpipe, so I went with AP.
Maybe I'll be a lucky one. I didn't say anybody was wrong or anything do I don't see why you said that.

It's just as quiet while weighing less. Plus it has no exhaust packing to fail over time in the muffler\resonator.

Post #18 in this very thread! Amazingly hidden isn't it.

It addresses all of the shortcomings of the other pipes without creating any new drawbacks. Mine has ~40,000 fantastic and trouble free miles on it. Zero drone, zero rasp, zero fitment problems, zero hardware problems, and zero structural problems. And it keeps the natural tone of whatever cat-back you have. Have the stock? it sounds stock. Have the Borla? It sounds Borla. Have the Racing Beat? It sounds Racing Beat.

No other midpipe can make the same claim to all of these points simultaneously. None. Any other pipe is a complete waste of money.
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.

There's a reason there are so many "cheap" aftermarket parts for cars.. a few actually

1. Something can actually be made cheaply and work as intended. Sticker come to mind.
2. New car owners who get the modding bug come to forums like this and see some of the very awesome mods that have been done. They get the itch and decide to start modding their own cars. It's at this point one of two things happen:
a: These people don't have a lot of money and buy cheap aftermarket parts for the feel of the actual mod without the cost. They know what they have isnt they real thing but they're doing it for the look (good or bad, usually very very bad) and they're fine with it

b:These people just don't have a clue or even an idea how to buy one. They instantly go to google and type in "rx8 whips, rx8 street, rx8 turbonator, rx8 bling, etc" and then start shopping. They see things that kinda look like something they saw here but OMG it's like 50 bucks and that douche on the boards said it would be a G.... They slap on their sideways baseball cap and go about their business of running up mommy or daddy's credit card on just some pretty horrible stuff.

I honestly can't fault anyone in either situation as long as the end result is that they are happy in the end, the problem lies in the fact that most of the b group will come here to get some level of praise and simply get torn a new A.

I'm using my money and not my parents. And only have around a grand right now. I don't want to blow it all at once.. I'm a college student with a girlfriend ( yes she is VERY expensive ).
My thoughts are: buy the AP pipe for 215 now and once it poops out, if it even does. Then I will buy a better midpipe when I have more money. Everyone drives differently so there are probably causes to why they break or give out. My friends ap pipe, like I said, still has no problems after about a year or so.

You are reducing your "more money" point by $215... Now instead of having to save $285 more, you have to save $500.



Forget anything else. The mathematics of it is astoundingly poor. Yes, I know how expensive women are (my wife has cost me far more than my 8). You are wasting money in the name of "saving money". If you don't want to spend $500 now, then stay with the OEM cat.
